Backwash Systems Provide Conservation and Treatment

Publication Date: 
August 26, 2015

H2Zero Backwash/Recycle Systems conserve water by storing and treating contaminated backwash water from filtration and treatment systems. Nearly all water filtration-related processes that remove target contaminants generate liquid or solid residuals that need to be subsequently managed. Increasingly stringent regulatory discharge standards and emphasis on sustainability are demanding more environmentally friendly solutions for these residuals.

CH2O Inc.
Deck: 

The new invention maintains free-flowing water in low-flow irrigation networks.

Low-flow irrigation networks have become more in demand as agriculturalists have been working toward sustainability and saving water. A disadvantage with these types of systems is that they are inclined to plugging. CH2O Inc.'s Chairman, Carl E. Iverson, has invented a water treatment method which promotes water flow in low-flow irrigation networks, and it has been issued U.S. Patent Number RE45,550 E. Fish & Richardson P.C. provided legal assistance during the patent issuing process.

The ion exchange system was designed, manufactured, installed and started up in less than 90 days

Envirogen Technologies Inc. has started up a high-efficiency ion exchange system for the treatment of hexavalent chromium in drinking water supplies for California Water Service (Cal Water) in Salinas, Calf.

This is the first permitted full-scale system to go online for treating hexavalent chromium since California's Division of Drinking Water (DDW) released a new maximum contaminant level (MCL) of 10 µg/L in July of 2014. The ion exchange system will treat groundwater sourced from a well in the Cal Water system to be more than 20% lower than the MCL.

Water Filter

Company Reference: 

The ChloraBlock cartridge filter provides four times the chloramine-reducing capacity and twice the chlorine-reducing capacity of standard carbon blocks. Key features include a large quantity of catalytically active nitrogen groups for effective chloramine reduction, a binder system that maximizes the availability of catalytic sites and 1-µ nominal filtration. The filter is suited for commercial, industrial and residential POU applications.

Keeping Up With the Times

Water quality—we use this term almost daily in the aquatics industry. It refers to the chemical, physical and biological characteristics of the water, and is the measure of the condition of the water relative to the requirements of one or more set of standards against which compliance can be determined.

Emergency Water

Company Reference: 

Blue Can manufactures pure water in sustainable aluminum packaging. The water has a 50-year shelf life and is targeted for the emergency and disaster preparation market, which commonly uses plastic bottles, packets or storage barrels, which have shorter shelf lives. The company uses a filtration and sterilization process, and when water is placed in the aluminum cans under pressure, it stays pure and fresh for decades.

The water treatment plants will use sodium hypochlorite for water disinfection

The cities of Groton and Norwich, Conn. will make significant upgrades to their drinking water treatment plants by eliminating the use of chlorine gas at these facilities. These actions settle claims by the U.S. Environmental Protection Agency (EPA) that the cities violated federal clean air laws meant to prevent chemical accidents.

Old Meets New

The design of water treatment systems often is based on the application of current solutions. Determining the best system at the time of installation can be done with information gained on site, or from experience harvested from other similar, successful applications.
