  • Residential water treatment - the next big class action litigation

    TTHM, MTBE, and Perchlorate. Mention these potential water contaminants around municipal water and wastewater supervisors, the Department of Defense, or the major U.S. oil producers, and see how fast the room clears! The major oil companies are back in litigation after the failure of current treatment technologies to remove MTBE contamination in residential drinking water supplies, the Department ...


  • The Use Of UV For Dechlorination

    For many years chemical disinfection techniques have been used to provide microbiologically pure water for industrial and domestic use. Free chlorine, typically introduced by municipal water treatment plants in gaseous form, has been employed for many decades as a primary oxidising agent for the control of microbiological growth. Free chlorine can also be introduced through the injection of ...

  • A Comparison of Operating Strategies – Chlorine vs UV

    ABSTRACTCity of Scott’s Valley owns and operates a 1.5 mgd activated sludge wastewater treatment plant. Currently about 0.3 mgd of the secondary effluent is diverted to the recycled water facility. Two chlorine disinfection alternatives (both using liquid sodium hypochlorite) and UV disinfection were considered to all the facility to achieve high level (Title 22) disinfection requirements from ...

  • 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 ...

  • Chemistries of Ozone for Municipal Pool and Spa Water Treatment

    Ozone generated by ultraviolet (UV) radiation is used in North America for treating (mostly residential) spa and pool waters almost exclusively, while only a handful of North American municipal pools and spas are using ozone generated by corona discharge technology in accordance with well–established German teachings. On the other hand, several thousand European municipal swimming pools and ...

  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...

  • 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 ...

  • 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 ...

  • The The `Design for Autonomous Net-Zero Water Buildings` Project Funded By NSF

    The students at the University of Miami will know firsthand the importance of rethinking the way we handle wastewater and water with a Net-Zero water treatment system on site.   The project showed the viability and feasibility to take buildings off the water grid to provide water recycling and how it can be achieved without raising the cost of high quality water. The research team ...

  • Rainwater recycling for HM Aylesbury Prison

    Rainwater recycling system for Aylesbury prison Aylesbury Prison, in Buckinghamshire, will cut its mains water usage in its new block by up to 50%, thanks to its new Aquaco rainwater recycling system. The rainwater recycling system will include 2 X 6,750 litre GRP collection tanks, water filtration and UV disinfection units. The recycling system is controlled by an Aquaco ...

  • Sanitation Using Ozone & Chlorine

    For nearly 100 years, ozone has been used all over the world for water sanitation. It is nature’s strongest oxidizer and has a byproduct of pure oxygen. Chlorine, on the other hand, is a very effective, time-proven chemical, but is ineffective against hard-to-kill microorganisms such as cryptosporidium. It also has some unpleasant byproducts. Together, however, these two substances can ...

  • Inetgrated Planning for Wastewater Treatment and Recycling for a Small Community Development

    ABSTRACTIntegrated water resources planning was conducted for Olowalu Town, a proposed development in western Maui, Hawaii. Total water needs, which can be supplied by a combination of diverted surface water, well water, recycled water and captured stormwater, are estimated at between 1 and 2 mgd. The Olowalu development will generate approximately 0.5 million gallons per day (mgd) of municipal ...

  • Wastewater Plant Relies on Thermal Flow Meter for Co-Gen Power Gas Blending Process

    The Rahway Valley Sewerage Authority (RVSA), which operates a large wastewater treatment plant in New Jersey, embarked on a green co-generation waste-to-energy project to power a portion of its operations. The plant performs primary, secondary, tertiary and sludge treatment processes in serving over 250,000 residential customers and 3000 industrial and commercial customers in a 40-plus square ...
