  • 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 ...


  • EM Pure Reverse Osmosis Systems

    The Problem More Dissolved Solids Than Desired In A Water Source Water is never completely free of dissolved solids. It contains varying amounts of impurities which are identified as hardness, alkalinity, minerals, inorganic salts, total dissolved solids or other items. Removal Of Unwanted Solids Suspended solids may be removed by ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Process Water Treatment – Challenges and Solutions

    Untitled Document Clean water is needed by chemical-process plants for a wide range of process-related and auxiliary uses. Likewise wide is the range of options available to the ...


  • What Is a Boiler Feed Water Treatment System and How Does It Work?

    For industrial companies using a boiler for its facility, some type of boiler feed water treatment system is usually necessary to ensure an efficient process and quality steam generation. The most appropriate boiler feed water treatment system will help the facility avoid costly plant downtime, expensive maintenance fees, and boiler failure as a result of scaling, ...

  • Preventing Rust Formation with Electronic Water Treatment

    The growing demand for water for industrial applications, power production and water supply has resulted in an increasing need for water treatment. The water used in industry comes from a range of sources such as rivers, lakes, wells and oceans and contains dissolved and suspended solids.  In addition the industrial world has to reuse water which in turn causes it to be highly concentrated ...

  • Membrane processing for water treatment in the semiconductor industry

    It is the aim of high-purity water production to either fully eliminate organic and ¡florganic compounds, particles, and microorganisms from the water or to reduce their concentrations to values below the detection limits of the most advanced analysis methods. Currently, this problem is solved by means of a multi-stage process chain, in which membrane technology ...

  • Electronic Water Treatment Reduces Fouling In Reverse Osmosis

    Reverse Osmosis (RO) is used in processes requiring high-quality, purified water, such in semi-conductor processing or biochemical applications and can be used to treat boiler feed water, industrial wastewater or process water. A water purification technique, it reduces the quantity of dissolved solids in solution. RO uses waterline pressure together with energy consuming pressurizing pumps that ...

  • Loading of an Anaerobic Packed Bed for Treatment of a High Strength Gray Water

    ABSTRACTIn preparation of long-duration manned space flight, biological treatment systems have been evaluated for mission specific waste streams consisting of a high-strength gray water. The purpose of the work was to determine the appropriateness of using nitrification and denitrification to treat the urine-humidity condensate waste stream and to determine the optimal loading rate for the bench ...

  • How to Choose the Best Boiler Feed Water Treatment Technologies for Your Plant

    When it comes to choosing technology for boiler feed water treatment, knowing the feed water source quality in relation to the water quality required for your specific boiler is essential, as inadequate water treatment can lead to the scaling, corrosion, and fouling of the boiler and downstream equipment. We’ve mentioned this before in some of our previous boiler feed water treatment ...
