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.
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.
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.
As recreational water technologies advance, so must codes & training
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.
The company added sales managers for the Northeast and central regions
HaloSource, parent company of the HaloKlear brand of environmental water treatment products, has expanded its sales team and added two new regional sales managers for the Northeast and central regions of the U.S.
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.
Process water system combines traditional & next-generation technologies
The research will be done in the university’s Water Quality Center
A group of professors in the Opus College of Engineering at Marquette University has received a $199,679 grant from the National Science Foundation to study drinking water treatment.
The research will be done in Marquette’s Water Quality Center, housed in the college’s Department of Civil, Construction and Environmental Engineering and led by Dr. Brooke Mayer, assistant professor. She will collaborate with Dr. Daniel Zitomer, professor and director of the Water Quality Center, and Dr. Patrick McNamara, assistant professor.
The facility is the only Pennsylvania facility to earn the Presidents Award this year
Pennsylvania American Water’s Norristown Water Treatment Plant, which serves approximately 32,000 customers in Montgomery County, has received the Presidents Award from the Partnership for Safe Water. The program is a volunteer initiative developed by the U.S. Environmental Protection Agency, Pennsylvania Department of Environmental Protection, American Water Works Assn. and other organizations representing water suppliers that continuously provide water quality that surpasses regulatory standards.
Despite global progress on drinking water, gains not trickling down to the most marginalized
Access to drinking water has been one of the biggest successes of the Millennium Development Goals, UNICEF said ahead of World Water Day, but for 748 million people around the world, just obtaining this essential service remains a challenge.
