Water recovery system reduces soft drink manufacturers water waste by 35%

The filtration and water treatment specialist Puresep provide leading soft drinks manufacturer with a state of the art system to reduce their water usage


Puresep were contacted to look at ways the soft drinks manufacturer could reduce the amount of rinse water sent to drain – in order to help them achieve their water reduction targets

Following an onsite review of the current rinse water configuration, Puresep made recommendations as to what improvements could be made to reduce the amount ofwater going to waste. The current situation involved four rinsing lines that washed bottles prior to being filled with product. The rinse water was then disposed of down the drain. This was a costly exercise as this waste was of high specification having been de-alkalised, UV sterilised and filtered.

Puresep looked at how this water could be re-used onsite. Each of the four rinsing production lines was fitted with a tank and a submersible pump system. The water from each production line fed into a single common recapture water line that filled a central storage tank.

Inline instrumentation was fitted to ensure the water was of the required specification prior to filling the storage tank. This is controlled using valves and a central PLC. Any out of specification water was sent to waste. The central storage tank was fitted with monitoring equipment to ensure the water continues to remain at the required specification. If the quality of this water degrades it is disposed of and the tank is re-filled with beverage line product make up water to bring the water back into specification.

Variable frequency drive pumps maintain the pressure within the ring main to feed the rinsers. The pressure in the ring main is adjusted by set points in the HMI system.

The return water is fed through a UV sterilisation system and through 10um and 1um absolute cartridge filtration. There are then take-off points to each of the four rinsers. If there is no demand for the water, it continually circulates around the ring main; flowing through the UV and Cartridge filtration systems to maintain sterility.

The environmental KPI goal for the site was to reduce water waste by 2.5%. Following the installation and commissioning by Puresep of the new recovery system the water wastage was reduced by 35%. This amounts to huge cost savings across the production line and a major achievement in meeting the manufacturer’s environmental.

Engineering Manager says:“….Puresep’s expertise and knowledge enabled them to see how modifications to an existing system couldbring major benefits. Puresep project managed the whole process from design, installation to commissioning. The attention to detail and onsite work is outstanding”


Envirogen Launches EnviroHPA™

Envirogen Launches EnviroHPA™ Service Program as  High-Performance, Cost-Effective Alternative to Activated Carbon Systems in Hydrocarbon & Chemical Processing Industries

Advanced Adsorbent Media and Custom Designed Systems Deliver Guaranteed Performance with Low- to No-Capital Investment and 20-50% Savings
versus Carbon Systems

Kingwood, TX, 14 November 2012 — Envirogen Technologies, Inc. (Envirogen) announced that it has launched a service program that represents a 21st Century alternative to environmental treatment applications that might otherwise feature activated carbon as an adsorption medium. Called EnviroHPA™ Systems, the offering features a range of ultra-high performing adsorbent media in systems designed, guaranteed and operated by Envirogen under multi-year agreements. Improved performance is seen in smaller footprint systems that can handle a wide variety of organic contaminants with excellent control and a minimum of system upsets. Envirogen offers EnviroHPA Systems as a service in which system design and installation, media costs, regeneration and disposal are charged as an operating fee over the life of the system. They can be offered with low- to no-capital investment, guaranteed performance and predictable costs over the service life of the installation. Savings with EnviroHPA Systems can approach 50% when compared with traditional activated carbon systems in high volume applications. An additional benefit of an EnviroHPA System is the substantially smaller carbon footprint of this approach compared to activated carbon systems. The initial applications for EnviroHPA Systems will be in the hydrocarbon processing and chemical processing industries for removal and recovery of select organics from wastewater, groundwater and vapor phase streams. Envirogen expects to have similar offerings for potable groundwater treatment, municipal wastewater treatment and other applications in the near future.

According to Robert Stark, Vice President, Southern Region for Envirogen, the synergistic combination of process expertise, high-tech media and service program is key to the dramatic cost-reductions available with EnviroHPA Systems. “Activated carbon has been an excellent tool in environmental treatment for decades for its low cost and adaptability into different applications. However, advances in material science have given us a whole new range of adsorbing media, which when expertly applied, have incredible performance characteristics and offer significant improvements in both treatment efficiency and cost performance. With EnviroHPA Systems, we can achieve both,” he said. “In the past, the high initial costs and the complexities of working with these high performance media have been considered, by some, to present risk that would not justify moving away from dated activated carbon systems. Because of our thirty-plus years of experience with adsorptive media and our system design capabilities, Envirogen has been able to eliminate the risk to customers and to guarantee performance and costs over the life of an installation. This sets the stage for the dramatic cost and carbon footprint reductions we can now offer,” he added. 

Advanced media technology key to performance and costs


For industrial aqueous and vapor phase treatment applications, Envirogen employs synthetic adsorbents manufactured by The Dow Chemical Company (DOW). These adsorbents offer a very high surface area and optimized pore size distribution – characteristics that offer substantially increased absorption capacity, rapid adsorption kinetics, a range of desorption options and excellent physical and chemical stability. Faster kinetics and higher contaminant loading can translate into higher hydraulic rates with a smaller system footprint – decreasing operations and maintenance costs for the treatment process and lowering initial capital expenditures for overall site improvements and utilities that accompany an adsorbent installation.


Enhanced desorption characteristics allow media to be regenerated in place with heat, steam, aqueous acids or bases – leading to an extended media bed life in use. The extended bed life of EnviroHPA System media is critical to a number of advantages over activated carbon. These include substantially lower lifecycle media costs when activated carbon must be reactivated or disposed off-site when it is spent, because of the energy that is required to conduct the reactivate or transportation and disposal costs. In-place reactivation eliminates the transportation associated with supply and removal of activated carbon from the site, and can offer significant reduction in the scale of site improvements and truck traffic. Regeneration of the EnviroHPA System media provides a more predictable, lower cost for operation and maintenance over the life of the project – especially when fluctuating prices for activated carbon are factored in. It is also a more sustainable solution with lower energy consumption and CO2 emissions.


According to Dr. Bob Goltz, a 30-year Separation Scientist and DOW veteran, with proper system design, operations and management, DOW synthetic media has the potential to substantially reduce lifecycle costs and treat difficult waste streams. “DOW is pleased to be working with Envirogen and stands ready to assist with decades of product and application development expertise for use of our products in aqueous and vapor phase applications,” he said.


Bob Stark agrees that the performance and economics of the EnviroHPA Systems merit a long look by environmental facility managers and consulting engineers who are considering or using activated carbon as a treatment technology. “We’re very excited about the opportunity EnviroHPA Systems represent as a high-performing, cost-effective alternative to activated carbon installations – and to working with DOW to optimize this technology for the market. In many instances, we are able to offer predictable, lower operating costs, and guaranteed performance for the life of these installations. And, we’re doing it in a way that is better for the environment – by lowering the overall carbon footprint,” he said. “While certain applications and contaminant types are a better fit for EnviroHPA Systems, today, we feel that anyone who is looking at activated carbon should consider the EnviroHPA Systems approach,” he added.

Envirogen Awarded Contract for Odor Control Systems

Envirogen Awarded Contract for Two Odor Control Systems at Central North Carolina Wastewater Utility

Project will feature two different biofilter designs to deliver best-cost, long-term solution

Kingwood, TX, 21 August 2012 — Envirogen Technologies, Inc. (Envirogen) announced today that it has been awarded a contract to supply two biological odor control systems as part of a Western Wake Regional Wastewater Management Facility (WWRWMF) construction initiative, managed by the Town of Cary, NC and its municipal partners (the towns of Apex, Morrisville and Holly Springs, NC). The two systems will utilize Envirogen’s proven biofiltration technology to remove odors and 99% of hydrogen sulfide (H2S) from air at the wastewater operation’s West Cary and Beaver Creek pump stations. The West Cary site will feature Envirogen’s new BTF-4500 modular vessel design, while the Beaver Creek site will receive a custom-designed built-in-place biofilter. Envirogen will also provide on-site customer support and training to assist in start-up, and a 10-year warranty covering media life.


According to Robert L. Loken, Vice President, Product Management and Great Lakes Region for Envirogen, the two systems illustrate the company’s ability to design and build high-performance, low-cost systems that are tailored to specific customer needs. “We’ve long offered a full range of system sizes and options, from smaller modular systems up to large, custom built-in-place installations,” Loken said. “The introduction of the BTF-4500 to our odor control product line allows us to offer the functionality of two treatment systems – biotrickling for H2S and biofilter for further odor reduction – in a pre-fabricated fiberglass vessel that provides the same reliable, low-cost performance and design excellence that Envirogen is known for. As always, the customer wins by getting just the right system to best meet all their requirements,” he added.

The new odor control systems at West Cary and Beaver Creek will handle H2S concentrations of 20-40 parts per million by volume (ppmv) at respective air flow rates of 6,700 and 8,250 cubic feet per meter (cfm). Both will achieve 99% H2S removal along with control of total odor. The Beaver Creek system will consist of a covered, poured-in-place concrete treatment vessel, while the BTF-4500 system at West Cary will be a pre-fabricated corrosion-resistant fiberglass treatment vessel ready for placement on a simple, compacted stone foundation. Envirogen’s new BTF odor control series features the benefits of a high efficiency biotrickling system for H2S removal and humidification in a short empty bed reaction time (EBRT) (7-10 sec.) The second stage biofilter is designed to work on mercaptans and tough-to-treat odors such as dimethyl sulfide. The biotrickling portion operates at a low pH of 1-2 with the appropriate bacteria, and has a continuous recirculation system. The biofilter portion of the design operates at a neutral pH with the appropriate media and bacteria for digestion of mercaptans and other organic odors (20-40 sec. EBRT). This represents the “state of the art” in packaged designed systems. Envirogen will also provide on-site customer support and training to assist in start-up. Long-term lifecycle costs are addressed via a 10-year warranty covering media life. Both systems are currently in the design phase, with equipment delivery anticipated by the end of 2012.

Envirogen’s biofilter product line features a set of engineered media matched to each specific application, ensuring high performance and a long media service life. Naturally occurring microorganisms residing on the media consume odor-causing compounds, requiring only irrigation water and small amounts of nutrients to operate. The systems use minimal energy, and little or no chemicals, cutting operating costs and eliminating the need for chemical storage and handling. Envirogen’s biofiltration is a sustainable “green” technology, providing long-term trouble-free service with little or no operator attention and minimal chemical and energy usage.

According to Loken, the design flexibility of Envirogen’s biofilter and biotower product line allows the company to design systems precisely matched to customer requirements and also to develop synergistic options and opportunities for improved performance. “Even when faced with rigorous performance standards, our engineers can develop a treatment scheme that delivers the best solution at the lowest cost,” Loken explained. “For this latest project, we went with two different system designs in order to address various factors affecting the two sites, including construction conditions. In the process, we were able to achieve significant cost savings for the client compared to taking a ‘one-size-fits-all’ approach to their specifications. At Envirogen, we’re always eager to bring our full range of technology and expertise to bear on helping the customer meet their treatment goals reliably and economically,” he concluded.

EcoSave Range of cost efficient and environmentally friendly water softeners

Environmental Water Systems (UK), launches the EcoSave Range of cost efficient and environmentally friendly water softeners

Environmental Water Systems UK, (EWS (UK)) today announced the launch of the new volume controlled counter current range of EcoSave Water Softeners offering reliable and economical operation, along with significant cost savings and reduced negative impact on the environment.

The softeners are volume-controlled plants and therefore extremely economical, allowing the plant to reach its full capacity before an automatic regeneration and exchange between filter tanks takes place. The plant supplies soft water during regeneration enabling con­tinuous operation. The unit runs in reverse flow, i.e. operation and regeneration flow in opposing directions. This results in extremely low salt and water consumption and minimal “leakage” during operation.

Plant is simple in design and configuration can be flexible to suit the plant area available.

The unit is con­trolled by a PLC making it possible to alter the operating conditions. This is connected to a monitor at the front of the panel so that all operating parameters can be monitored.  

There is the additional option of installing a conductivity meter to monitor the rinse stages – allowing potential water wastage reduction by 25-35 %. The conductivity meter will measure the rinse water quality and will halt the rinse cycle when the conductivity meter reaches a pre-set value, normally set at worst case inlet water quality. To measure the quality of the soft water, a Testomat can be installed. This can be set to trigger an alarm if the water hardness increases above a pre-set value. In addition the read out on the monitor will indicate the hardness of the water in the display of the control panel.

Advantages the EcoSave softeners bring to the end user include:

  • Reduction in water consumption by as much as 80% when compared with conventional water softeners
  • Significant cost savings
  • Simple design resulting in less maintenance
  • reliable and safe
  • Typical pay back can be 12 – 18months

EWS(UK) have devised a simple to use cost benefit analysis tool that can give end users a clear idea of the cost savings when comparing to the existing installation or a new softener. As well as giving the expect payback timeframe.

Dave Hayes, Sales Director says “this is a key product for our end users at a time when water shortages are rife. To enable our customers to clearly see the cost and water savings they could be making and over what time frame is an invaluable tool”



New Small-Scale Fluidized Bed Reactor Systems

Compact, Containerizable Systems Suited for Remote, Small Flows and Can be “Networked” for Cost-Effective Treatment of Multiple Outfalls

Envirogen Technologies, Inc. (Envirogen) announced today that it has introduced a new small-footprint fluidized bed reactor (FBR) system designed to treat low flows of selenium-laden coal mining waters economically and efficiently. The new systems will allow coal mine operators to treat flows that start at less than 100 gallons per minute (gpm) to lower than 5 μg/L selenium at discharge – even in the presence of high levels of nitrate. These systems can be automated and delivered in standard-sized ISO containers to difficult-to-reach locations that require minimal site preparation and engineering, and can be monitored remotely. The new small system FBR approach offers coal mine operators the ability to treat selected mining water outfalls with a relatively low initial capital expenditure and the flexibility to relocate the systems to meet changing treatment goals.

Envirogen entered the coal mining selenium treatment business in 2011 with its FBR technology that has been deemed ‘best-in-class’ for performance and cost effectiveness by an independent study developed for the North American Metals Council. The company now offers containerized and built-in-place FBR systems that can be sized to treat a wide range of flows and influent water compositions, ranging from under 100 gpm to well over 3,000 gpm. Envirogen has recently completed several long-term operational studies with FBR systems in coal mining operations in Appalachia and Western Canada, demonstrating the effectiveness of the technology in the field.

According to David Enegess, Vice President, East Region for Envirogen, the move to develop small FBR systems was motivated by the realities of treating selenium-containing wastewaters in coal mining operations that have multiple outfalls – often in remote locations – as opposed to a single option that would require the construction of a large, centralized facility. “Coal mining is a very dynamic activity, often conducted in rough, remote terrain. Sometimes it is impractical to pipe all the selenium-containing mining waters to a single, centralized facility from both cost and logistics standpoints. The smaller-sized FBR can meet the treatment and discharge requirements of low-flow outfalls. It can be rapidly implemented with a minimal amount of civil engineering, automated and remotely monitored. These systems become an asset that may be relocated if treatment locations vary on one site, or across multiple sites, through time,” he said. “For mines that have multiple outfalls, we envision these being treated by individual small FBRs, with other activities – such as solids treatment and disposal, chemical supply and spare parts serviced from a lower cost centralized location,” he added.

The Fluidized Bed Reactor – “Best-in-Class” Technology

Envirogen’s FBR is an active, fixed-film bioreactor that fosters the growth of microorganisms on a hydraulically fluidized bed of specified media. FBRs have been shown to have some significant advantages over other biological systems in coal mining environments in treating selenium to less than 5 μg/L. First, they operate in a steady-state ‘plug flow’ manner that avoids channeling, upsets in the controlled growth of organisms and gas binding. This ensures that the microorganisms in the system are optimally utilized. Also, they do not require periodic backwash, as do packed bed reactors, for example. These features allow for significantly higher treatment efficiency, resulting in much lower hydraulic residence times (1/5 to 1/10 as long as packed bed). This efficiency results in smaller overall systems and a smaller system footprint – both of which contribute to the dramatically lower capital and installation costs of the FBR compared to other biological treatment systems. Its flexibility in the choice of electron donor chemicals can translate into capital and operating cost savings with reduced solids generation. It also responds well to changes in feed flow and composition, consistently achieving discharge limit conditions.

With a team that has more than 20 years of experience operating the FBR treating similar inorganic compounds like nitrate and perchlorate, Envirogen has the expertise and the ability to offer performance, cost and asset life guarantees in conjunction with these small FBR installations. According to Mr. Enegess, the focus with any solution development will be low lifecycle cost. “As we look around the coal mining industry today, we see the need for high-performing treatment solutions that are flexible enough to meet each coal mine’s approach to handling selenium abatement. But we also understand that cost is a major issue,” he said. “With our FBR technology, we start with the most robust, cost-effective technology on the market. In partnering with the coal mining industry, we can help design and implement technology and long-term operating solutions that will deliver the lowest lifecycle cost over the course of the treatment program,” he added. Mr. Enegess went on to point out that the company is involved in using FBR technology to treat selenium-laden waters in other industries and applications – including other mining industries, power generation, refinery wastewaters and in agricultural and groundwater remediation applications.
