  • Methods of Water Purification

    This article is excerpted from 'Pure Water Handbook' published by Osmonics®, Inc. of Minnetonka, Minnesota USA and is printed with permission of Osmonics, Inc. Water treatment can be defined as any procedure or method used to alter the chemical composition or natural 'behavior' of a water supply. Water supplies are classified as either surface water or groundwater. The majority of public or ...

  • Methods of Purification

    Water Innovations Water Systems Carbon Filtration is used for several reasons. Its primary purpose is the reduction of chlorine to less than 0.1 ppm. Chorine can damage softener resins, reverse osmosis membranes, and mixed bed deionization resins. Activated carbon will also help control tastes and odors, provide organic and hazardous organic chemical ...

  • How LEDs Will Change Water Purification

    Ultraviolet (UV) light has been naturally purifying water for centuries. With clear skies, our sun can inactivate water-based pathogens in six hours minimum. Cloudy skies or unclear water causes imperfect conditions. These conditions allow for bacteria to grow and make natural water sources unsafe to use. Fortunately, we have developed several types of water disinfection, ranging from chemicals ...

  • Wastewater sterilization (purification): completely new method “vortex layer machine”

    The purification and safe disposal (neutralization) of industrial waste water effluents represent a very important ecological problem. The principal problem or requirement involves reducing the concentration of harmful impurities to concentration levels below their maximum allowable concentration limits. In fulfilling this requirement the amount of fresh water consumption needed to maintain the ...

  • Steel coating mill saves $450k. with fluid purification program

    The Problem: A leading manufacturer of electro-galvanized and aluminized steel coil products, used as body panels in the automotive industry, was experiencing quality defect issues due to residual surface oil left on the parts after cleaning operation. In order to meet the surface finish specifications of the finished sheet, the mill requires all incoming steel coil stock to be pickled and oiled ...

  • Evaluation of a silver-ion based purification system for rainwater harvesting at a small-scale community level

    Silver has been known for centuries to be a powerful disinfectant, with no known harmful effects to humans if applied in adequate doses. Although its use was partially discontinued with the advent of chlorination and modern antibiotics, the discovery of bacterial resistance and disinfection by-products has enabled its re-emergence as a viable water purification option. On the other hand, ...

  • Amine Purification System (AmiPur®) – Continuous Heat Stable Salts Removal from Amine Solutions

    1.Introduction Amine scrubbing solutions are used to remove hydrogen sulfide (H2S) and carbon dioxide (CO2) from gas streams and LPG in many oil refineries and natural gas conditioning plants. Due to its high selectivity to H2S, Methyldiethanolamine (MDEA) is most commonly used to remove H2S in the presence of CO2 from gas streams and LPG. Amine plant operational problems, such as ...

  • Membrane cleaning skids prolong operating life of costly membrane filtration units

    Considered one of the most important and costly components of a reverse osmosis purification system, membrane filtration elements (a thin semi-permeable layer which desalinates seawater) collect mineral buildup, organic materials and bacterial agents. The Lifestream Membrane Cleaning Skid cleans, flushes out and preserves the membrane, reviving efficiency and prolonging membrane life.Designing a ...

  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

  • Membrane Distillation and Applications for Water

    SummaryWater treatment is an important auxiliary process in all thermal cogeneration plants. In this context membrane distillation (MD) is a novel technology that is potentially advantageous to technologies like reverse osmosis in the following ways: ability to utilize low-grade heat, reduced sensitivity to fluctuations in pH or salt concentrations, and lower capital and O&M costs. This ...

  • Carlos Perea`83 `Water is life.`

    Incorporated in 1994, MIOX uses mixed-oxidant technology, originally developed in 1982 by Los Alamos Technical Associates (LATA), to purify water. At the time, LATA was under contract to the U.S. Army to create a portable unit to disinfect water anywhere in the world without requiring dangerous or difficult-to-obtain chemicals. The first patent for the MIOX technology was issued in 1988, and the ...

  • Seawater Biotoxicity monitoring to protect the coastal waters of Italy

    The recorded death of fish in the river that flows out of the industrial zone of Scarlino has created the need of the installation of a biological alarm system. The decision was made to work with an automatic system, iTOXcontrol created by microLAN-The Netherlands represented in Italy by Ecotox Lds, which uses marine bacteria. The system compares the values of the light emission from these ...

  • Ultraviolet Light Oxidation of Free-Chlorine in Water

    Chlorine is the most frequently used chemical for water disinfection. Many industrial and commercial manufacturing facilities cannot tolerate the introduction of chlorine into the process because of contamination and unwanted chemical reactions. Chlorine affects the flavour and odour of drinks and fluids, accelerates corrosion on process vessels and piping, and can also damage delicate process ...

  • Water glycol recovery saves over $20,000

    The Problem: At a mid-Michigan automotive supplier, a shutdown was imminent. Accidental cross-contamination between fire-resistant and oil-based hydraulic fluids in a bulk tank left the plant vulnerable to fire. If plant employees topped off or filled their reservoirs from the direct-fill system available at each machine, the risk of a fire propagating in the plant would greatly increase. ...
