  • 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 ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • 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 ...

  • Case study - Purification of biogas in EDAR Mapocho

    BIOCONSERVACION: Integral solution for biogas purification in WWTPs Biogas is mainly composed by methane and carbon dioxide as a result of organic matter fermentation in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of biogas depends entirely on the nature of the waste processed and the conditions under which takes place the anaerobic digestion. ...

  • Lifestream watersystems provides water purification systems for new oil production facility and its community

    Lifestream Watersystems Inc. has provided three brackish water desalination syslems to a major oil producing company to yield 255,000 gallons per day of high qualify water for a new community of up to 3000 people to support a decade long project of oil production in a remote area. These systems will also provide a reliable supply of high purity industrial process water to the operations of the ...

  • 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, ...

  • 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 ...

  • Alternative water supply and treatment solutions in Durban (SA)

    As a result of persistent drought conditions in South Africa a customer (an international consumer goods producer with a production facility in Durban) experiences the pressure of limited availability of water. The ever dropping dam levels currently result in higher risk for intermittent water supply resulting in unplanned and forced production stops in case no water is available. Aquest Colsen ...

  • 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. ...

  • Crossflow Membrane Filtration High-Purity Water Systems

    INTRODUCTION As the electronics industry continues to provide us with such products as high resolution television, notebook size portable computers and cars with automatic navigation systems, it becomes necessary to produce semiconductors with finer device geometries to allow for efficient placement of more circuits per a given area. This requires increased control of a semiconductor's material ...

  • Theoretical operation of high-efficiency ultraviolet water treatment chamber
