  • Pure oxygen makes the grade

    The Bryn Posteg landfill site, which opened in 1982, is owned and run by Potters Waste Management and is located close to Llanidloes in mid Wales. Licensed for the disposal and treatment of household waste, the site is set in a remote area. The site has always been a full ‘containment’ site, which utilises natural impermeability and engineered systems to prevent leachate from being discharged ...

  • HF Pure Water visits the Middle East

    HF Pure Water recently participated in the Water, Energy, Technology and Environment Exhibition held in Dubai, UAE. In speaking with numerous people that visited the HF Pure Water booth, it became apparent that there were limited opportunities for waste water treatment as many manufacturers simply dumped their wastewater into the ocean. This was confirmed in a meeting held with the Dubai ...

  • HF Pure Water VS. The Coffee Borer Beetle

    Recently, HF Pure Water successfully installed a Chlorine Removal System at a small coffee farm on the big island of Hawaii. Like many coffee farms in the area and around the world, the coffee bean crop had been devastated by the Coffee Borer Beetle. An all-out effort was needed to rid the farm’s crops of this beetle as many small farms has had their entire crop destroyed, resulting in ...

  • Microbial Control and Sanitization of Membrane-Based Pure Water Treatment Systems

    Introduction Today's high technology water purification systems are designed to remove many types of impurities. One of the most difficult to deal with is microbiological contamination. Microbial growth in a water system presents two problems: it not only reduces water quality, but if left unattended, the problem can 'grow' to reduce system performance and life. Biofouling can cause a decrease ...


  • Electrolytic Ozone Generation And Its Application In Pure Water Systems

    Over the years manufacturers have become increasingly aware of the importance of water purity and its effect on the quality of the final product. One of the largest problems that confronts pure water system operators is bacterial recontamination shortly after the water purification equipment. There are several ...

  • Pure water from Kinetico at the Worcestershire Royal Hospital case study

    When the Worcestershire Royal Hospital opened, it had been equipped with a Kinetico water treatment system to supply pure hot water to its theatre areas and to washer disinfector units used for cleaning and disinfecting medical devices. In recent years, partly in response to concerns about the transmission of variant CJD via reusable surgical instruments; and also with regard to the risk ...

  • Counting the whole life cycle cost of pure water production

    In this article we define various grades of pure water, review technologies available for its production, and describe two systems where various process combinations have been used to generate pure water for pharmaceutical and power generation applications. We ask Dr John Hutcheson, a specialist consultant in pure water systems, what costs are involved in pure water production and what ...

  • Case study - Pure oxygen injection pilot test

    Introduction: The Moccasin Bend WWTP uses pure oxygen produced by a cryogenic oxygen plant for activated sludge treatment of the influent waste stream, which consists of municipal and industrial wastes. The waste stream contains a high proportion of high strength industrial waste, which results in a typical COD loading of about 2000 mg/L, which is approximately four times the strength ...

  • Energy and exergy analysis of a novel multigeneration system producing cooling, heating, power and pure water

    A novel multi–generation system producing power, pure water, cooling and heating is proposed and analysed in detail. The system comprises a hybrid generator-absorber heat exchanger (GAX), the Organic Rankine Cycle (ORC), the absorption heat transformer (AHT) and a desalination system. For comparison purposes, three working fluids, including R123, Isopentane and n–butane are considered in the ORC. ...

  • Pure Oxygen Plus Nitrification? Biowin Modeling Plus Full-Scale Experience

    ABSTRACT High Purity Oxygen (HPO) activated sludge treatment and nitrogen removal do not have to be mutually exclusive. Some HPO activated sludge treatment facilities in relatively warm climates must address recently implemented or upcoming regulatory changes that require reduction of effluent nitrogen discharge levels. The 48.75 mgd capacity (annual average) Hollywood Southern Regional ...

  • True Partnership: “It’s like pure is a true extension of our staff team—that’s what makes their relationship with WSSC work so well”

    The best relationships are built on trust and responsiveness. Collaboration between The Washington Suburban Sanitary Commission (WSSC) and Pure Technologies began in earnest nearly a decade ago, and continues today as the two partners work together as one unified team to ensure the overall health of ...

  • Water Purification Challenges: ZLD, EDI, COP systems

    Applied Water Solutions was contacted by a client who planned to move their manufacturing facility to an area where there is strict limitations on water discharge. Working close with the client we created a process flow diagram (PFD) using multiple water purification technologies that provided pure water generation, water recycling capabilities and offsite disposal of solids. From the PFD we then ...

  • High purify water systems for utility use

    Companies in the utility business have a need for high purity water for their operations such as in diesel generator cooling systems and in turbine generator makeup water. Often, utilities can not depend on the city water as the quality is not pure enough and purchasing local water may be expensive. To gain operational and economic advantages, water purification equipment can be added. These ...

  • A Case for Point-of-Use RO Ultrapure Water Systems

    ULTRAPURE WATER CRITERIA - AN OVERVIEW 'Pure water' is a relative term. Practically speaking, no water, naturally occurring or treated by man, consists solely of H2O molecules. Forever in pursuit of achieving equilibrium with its surroundings, water has unique characteristics that result in its ability to dissolve most matter. This property of water to dissolve and transport materials is ...

  • Continuous nonlinear model predictive control of a hybrid water system

    Incorporating weather forecasts in the control of land surface water levels requires predictions of the net inflow to the water system. This net inflow is the combined flow of an incoming load (rain, evaporation, etc.) and outgoing pump rates. Because the pump costs are considerable, optimal pump schedules have minimal energy consumption. Model predictive control (MPC) is able to compute, revise ...
