  • 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 ...

  • Electrocoagulation and nanofiltration integrated process application in purification of bilge water using response surface methodology

    Marine pollution has been considered an increasing problem because of the increase in sea transportation day by day. Therefore, a large volume of bilge water which contains petroleum, oil and hydrocarbons in high concentrations is generated from all types of ships. In this study, treatment of bilge water by electrocoagulation/electroflotation and nanofiltration integrated process is ...

  • Electrochemical degradation of PAH compounds in process water: a kinetic study on model solutions and a proof of concept study on runoff water from harbour sediment purification

    The present study has investigated the possibility to apply electrochemical oxidation in the treatment of polycyclic aromatic hydrocarbon (PAHs) pollutants in water. The reaction kinetics of naphthalene, fluoranthene, and pyrene oxidation have been studied in a batch recirculation experimental setup applying a commercial one-compartment cell of tubular design with Ti/Pt90-Ir10 anode. The rate of ...

  • The importance of Water Treatment in industry

    Water treatment is an important industry requirement and comes under 4 main branches which include boiler water treatment, cooling water treatment, water purification and the treatment of wastewater effluent. It is considered that these cover the majority of Water treatment processes in the UK and Internationally. Water treatment is often seen as an additional cost on top of an already very ...

  • City Water International explains The Basics of Water Filtration

    The Basics of Water Filtration Most of us know that filtered water is healthier than tap water because of its purity, but how does water filtration work? The basic principle is that filtered water has passed through a filter which removes contaminants through one of several methods, depending on the type of filter. Most water purification systems work in one of three ways ­ by running water ...

  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Sea Water Desalination - Technical Article

    Sea Water Desalination is a specific process involving molecular separation via membrane technology to reduce the dissolved salt and mineral content of sea water to a level suitable for human and animal consumption, commercial/industrial and irrigation uses. This process involves three water streams namely sea water as the intake source, Product / Permeate water of potable drinking water quality ...

  • Water Treatment in Microbrewery application - Case Study

    Point-of-Entry (POE) Water Treatment Used for Chlorine Removal in Microbrewery Application Summary: RO is the preferred technology for many commercial/light industrial applications where feed water purification and final product water consistency are essential. Growth of U.S. microbreweries has created an opportunity for this application. The following case study offers an additional area of ...

  • 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 ...

  • Ozone is Not Just for Residential Potable Water Treatment

    It has been over 170 years since the d iscovery of the ozone (O3) molecule. Since that time, scientists and engineers have been testing and evaluating ways to use ozone in many different processes, from water and air treatment to surface and food sanitation. The evolution was somewhat slow in the early days, taking nearly 50 years before Europeans found, in 1886, that ozone could be used for ...

  • Spiral-Wound Elements for Potable Water Treatment

    Introduction Any new technology must overcome perceptions of the marketplace, which are not accurate. As a technology moves into new areas of application, new misconceptions also arise. Crossflow membrane technology is no exception. The first man-made, pressure-driven 'crossflow' membranes were made in flat sheet form. This membrane had to be configured in a device, and was first made in ...


  • Immersed Membrane Technology for Advanced Wastewater Treatment & Water Reuse

    A significant segment of the North American population is unserviced by municipal wastewater systems and, with the seemingly, unending growth of residential communities, commercial complexes, industrial parks and support infrastructure, this situation is unlikely to change in the foreseeable future. Traditionally serviced by on-site wastewater treatment units, and often relying on groundwater ...


  • Application of Membrane Technology for the Recovery and Reuse of Water

    Abstract As water and sewer costs are expected to increase over the next decade, membrane technology will continue to be a viable and economical option in the recovery and reuse of water. This paper describes the mechanism of membrane effected separation (specifically reverse osmosis, ultrafiltration and microfiltration), membranes commercially available, membrane element configurations, and how ...


  • Natural clinoptilolite composite membranes on tubular stainless steel supports for water softening

    Disk membranes generated from high-purity natural clinoptilolite mineral rock have shown promising water desalination and de-oiling performance. In order to scale up production of these types of membranes for industrial wastewater treatment applications, a coating strategy was devised. A composite mixture of natural clinoptilolite from St. Cloud (Winston, NM, USA) and aluminum phosphate was ...

  • In the World: Small Mexican village produces clean water with solar-powered system

    MIT-developed system runs autonomously, producing 1,000 liters per day. In a small village deep in the jungles of the Yucatan Peninsula — a day’s drive from any source of clean, drinkable water — researchers from MIT are testing a system that purifies water with the help of the sun. The relatively inexpensive system consists of several modest photovoltaic panels, a large ...
