Cartridge system certified
Applied Process Equipment, Inc. announ-ced that its Applied Cartridge Systems, a commercial water treatment product line, has been fully NSF/ANSI/CAN 61-certified for potable water. These systems are installed in water utilities, RV parks, hotels, casinos and resorts, military bases, aquaculture and food processing applications, manufacturing plants, subdivisions and multi-user wells of all sizes across North America. Each cartridge system comes complete with 304 stainless steel housings, prefilters and cartridges, all NSF 61-certified together as a package.
Centennial celebration for MWWA announced
The Minnesota Water Well Association (MWWA) will celebrate 100 years of service to the groundwater industry this year, a milestone that is rare in the water industry. The organization, which was formed in 1922, represents Minnesota’s groundwater professionals including water well contractors, groundwater scientists, pump installers, and manufacturers of groundwater technology. The MWWA celebrated its anniversary as part of its annual trade show in late January. To further recognize MWWA’s 100 years of service to the State of Minnesota, Governor Tim Walz declared January 31 as ‘Minnesota Water Well Association Day’ through a state proclamation.
Resin price increases announced
According to PR Web, Dupont announced an up-to-15-percent price increase for products/across/its ion exchange resin portfolio, effective February 1, as local regulations and contracts allow. Account managers will provide customers with specific details for the products purchased from DuPont Water Solutions. All new orders will be confirmed at the new price. In some cases, existing orders confirmed at previous pricing but invoicing on or after the effective date will be reconfirmed at the higher price if permitted under the specific legal framework in the country the sales transaction is conducted.
Should other DBPs be considered for regulation?
According to a paper in Environmental Science & Technology, researchers surveyed both conventional and advanced disinfection processes in the US, testing the quality of their drinking waters. Treatment plants with advanced removal technologies (such as activated carbon) formed fewer types and lower levels of DBPs in their water. Based on the prevalence and cytotoxicity of haloacetonitriles and iodoacetic acids within some of the treated waters, the researchers recommend that these two groups be considered when forming future water quality regulations.
Pentair residential water treatment offerings expanded

Research announced: kombaucha for membrane filtration
According to a recent paper published in the ACS journal ES&T Water, kombucha tea might also hold the key to affordable, environmentally sustainable living membranes for water filtration. Experiments by researchers at Montana Technological University and Arizona State University showed that membranes grown from kombucha (symbiotic culture of bacteria and yeast or SCOBY) cultures were better at preventing the formation of biofilms, a significant challenge in water filtration, than current commercial membranes. That team was able to engineer the cells in the yeast to produce glow-in-the-dark enzymes that could sense pollutants and then break them down after detection. One of their prototype materials senses the pollutant estradiol, while another could detect luciferase, a bioluminescent protein. Any number of other strains can be swapped out to achieve different functional properties.
New DBP standard proposed
ASTM International’s water committee (D19) is developing a proposed standard that water quality laboratories will use to help ensure that environmental regulations for water are met. The proposed standard will provide an early warning prediction from raw source water of DBPs that are formed when natural organic matter in water reacts with disinfectants added to kill bacteria in water treatment plants. Drinking water treatment plant operators, managers and water quality laboratories will find the proposed standard useful, as it will help mitigate the risk of DBP compliance violations in a forward manner and help to minimize public exposure to contaminants. The proposed standard will help raise public awareness on DBP contamination issues and it will expand the service capabilities and/or reduce turnaround time for laboratory analysis.
Grundfos agreement announced
EKF (Denmark’s Export Credit Agency) and Grundfos and have entered into an agreement, enabling the latter to finance projects globally for private commercial and public customers with limited funds available. The agreement is the first of its kind in the pump solutions industry and creates new opportunities for Grundfos to finance projects that will further access to water and optimized use of water resources. Moreover, it can help customers meeting their ambitions for reduced carbon emissions. Under the agreement, private commercial and public customers can receive financing on projects above 0.5 million EUR ($0.57 million USD) for up to five years directly through Grundfos. EKF will provide the company with a credit guarantee covering 50 percent of the credit exposure significantly reducing the risk in financing such projects.
