The winning project introduced a filter that removes toxic heavy metals from drinking water and industrial wastewater
Perry Alagappan from Houston has won the 2015 Stockholm Junior Water Prize (SJWP)—an international competition for water-related research. The Prize Patron, H.R.H. Crown Princess Victoria of Sweden, presented him with the award at an Aug. 25 ceremony during World Water Week in Stockholm.
CMF charged membrane filtration for microbial retention is a viable alternative to standard membrane technology at higher flow and less pressure drop. The membrane is designed with a non-woven electroadsorptive media with strong positive zeta potential for net retention efficiency of 0.002 μ, with low psid (less than 3 clean) and change out up to 35 psid at 160°F. These pleated cartridges are entirely sonic welded and do not use potted end caps or solvents. Applications include drinking water, bottled water, food and beverage, showers, process water, misting systems and more.
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.
Home and business owners face a variety of challenges in maintaining a high level of water quality for their families and customers. Every municipality is subject to common contaminants that are found in its tap water.
H2O International’s Inline (IL) Whole-House series of water filters is the ideal filtration solution for a business or large home. Instead of filtering water at the faucet or another point of use, the IL whole-house systems filter water at the point of entry, ensuring that all the water entering the home or building is safe and clean.
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.
The water filtration system began providing water to villagers in early March
A Pall Aria water filtration system is providing clean drinking water to residents of Grande-Saline, a remote village in northwest Haiti. The system was donated by Pall Corp.
Customized solution eliminates taste and odor issues in drinking water
Xylem Inc. unveiled a new drinking water treatment solution that removes challenging contaminants, including contaminants of emerging concern, at ACE15, the American Water Works Ass.’s annual conference and exposition, which took place in Anaheim, Calif., June 7 to 10. Xylem’s Leopold Oxelia is a multi-barrier solution; an oxidation-enhanced, biologically active filtration system that enables the production of a safe and reliable supply of clear and biologically stable, treated water with no taste or odor issues.
The distillation process runs on energy-efficient fuels such as waste heat and solar energy
Somenath Mitra, professor of chemistry and environmental science at the New Jersey Institute of Technology, was awarded a patent last month for a next-generation water desalination and purification technology that uses carbon nanotubes to remove salt and pollutants from brackish water and industrial effluent for reuse by businesses and households.
