  • Dissolved Solids and Water Purification

    To make drinking water palatable, the level of dissolved substances (TDS) can’t be too high, but it also can’t be too low Water quality metrics are needed to ensure that surface and groundwater – common sources of water for human consumption – are free from contaminants and pollutants. The level of dissolved solids, also commonly referred to as total ...

  • Measurement of oxygen during the purification of glycerin – Case Study

    Background information Glycerin is a basic chemical which is used in creams and ointments, in antifreeze and brake fluid for vehicles, as a plasticizer, and as a base for paints and lacquers. Glycerin is produced as a by-product during the manufacture of soap. This was the main source of glycerin for many years. However, the production of biodiesel has increased greatly in the last ...

  • Why is drinking water treatment necessary?

    Water is found in ample amount almost everywhere on earth. The natural water resources such as lakes, rivers, etc. that provide water contain a lot of pollution, garbage which is unfit for human consumption. To clean the water, it should undergo numerous water treatment media procedures that make it suitable to drink. The water ...

  • How to Deal with Arsenic in Drinking Water

    Thanks to recent developments in technology, daily drinking water undergoes a rigorous treatment process for water to be consumable. This is because most ground and natural river waters have a chemical in them called arsenic. Arsenic is a metallic chemical element that is found commonly among rocks and sulfur in the Earth’s crust. Arsenic is known for getting into your drinking water from ...

  • Methods of Purification by Water Innovations, Inc.

    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 reduction, and some particulate reduction. ...

  • What is an Ion Exchange System and How Does it Work?

    Ion exchange (IX) systems are used across a variety of industries for water softening, purification, and separation purposes. While the chemistry of individual ion exchange reactions vary from one application to the next, IX is a treatment process where dissolved ions are replaced by other, more desirable, ions of a similar electrical charge. If you’re wondering whether IX is right for your ...

  • MBBR Wastewater Treatment - 5 Top Advantages

    Modular wastewater treatment solutions have become very important to treat waste water. Water scarcity has become an important issue worldwide, requiring strategies for both water conservation and effective water and wastewater treatment. Several technologies have been in practice for generations including the conventional activated sludge process.  ...

  • Solar Tech could provide clean water in rural india

    University of Edinburgh researchers are working on low-cost, low-energy technologies to simply and effectively treat wastewater, which could provide clean drinking water to residents in rural, remote areas of India and also stem the spread of diseases. The central material is an inexpensive, coated plastic that relies on light to create a chemical reaction. It absorbs sunlight, then activates ...

  • Case Study - Wiggins Road Water Purification Works

    ASW Engineering, a supplier of water treatment systems in southern Africa, was awarded the contract by Umgeni Water to refurbish 12 twin-cell rapid gravity sand filters. The company’s initial assessment of the problem was that the sealing between the filter nozzle sleeves and the concrete panels, and the sealant used in between the precast slabs of the filter floor, had deteriorated due to ...

  • Comparison of the water purification efficiency of two different flocculation-sediment-filtration (FSF) processes in Chaohu Lake in China

    A novel biofilter (BF) with the potential to improve pollutant removal when used as a substitute for sand filters in water purification processes is presented. To investigate BF's pollutant removal performance, a flocculation-sediment-biofiltration (FSBF) process was compared with a flocculation-sediment-sand filtration (FSSF) process on a lab scale, with water collected from Chaohu Lake. The ...

  • Case study - Filtralite in London

    World best filter material for purification of drinking When algal blooms put the sand filters under pressure, Thames Water started its own in-house research into new filter materials. Not only did the effort cure the constraint, the use of new filter materials has saved millions in investments. Fast Cleaning To purify water with sand takes a long ...

  • Novel thermoresponsive assemblies of co-grafted natural and synthetic polymers for water purification

    Water contamination and its purification are a global problem. The current approach to purify water is reduction of impurities to acceptable levels. One of the ways to achieve this is by use of water-soluble polymers that extract organic and metallic contaminants, from water. This paper presents a blend of composite polymers that eliminates both the contaminants simultaneously by the principle ...

  • We purify our waste­ water optimally

    Holzkirchen wastewater treatment plant achieves a new milestone in energy efficiency with AERsmart The Holzkirchen wastewater treatment plant has a clearly stated objective: “We purify our wastewater optimally.” For the municipal wastewater treatment plant, located 40 kilometres south of Munich, there is a requirement to operate in a way that is as resource-efficient as ...

  • 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 ...
