The health of the environment is an issue that no one person can solve alone. But thanks to engineering professors Mihri and Cengiz Ozkan of the University of California, Riverside, people will soon be able to make their own small impact on the world’s water quality simply by taking a swim. The Ozkans’ “Sponge” material is designed to remove toxins from water, and in the near future it may be a part of the swimsuit you wear when you go for a dip. WQP Associate Editor Michael Meyer spoke with the Ozkans about this new technology.
According to the U.S. Geological Survey, more than 85% of the U.S. has hard water. In plumbing, hard water leaves calcite deposits, commonly known as scale, that restrict water flow by occluding pipe. In water heaters, calcite coats heating elements, causing them to overheat and eventually fail. Standard approaches to calcite mitigation rely on chemicals (salts) or ultra-fine membrane filtration.

For decades, reverse osmosis (RO) has been a key player in the point-of-use (POU) and point-of-entry water quality improvement market. Natural osmosis results in the passage of a fluid from a solution with a low concentration to a solution with a higher concentration until equilibrium is achieved. Reversing this process, RO uses pressure, whether from the influent water supply or a booster pump, to overcome the natural osmosis process and force the opposite transition of high-concentrate solution to low concentrate.

The PureChill line of PureWaterCoolers are two-temperature dispensers that use PureChill technology to eliminate the need for an open reservoir for coldwater storage. Three models offer filtered water that is chilled on demand when it passes through the cooling chamber to the faucet. The closed system keeps contaminants out so there is no need for costly in-tank sanitization.
Funds will be provided with an emphasis on small and disadvantaged communities
The U.S. Environmental Protection Agency (EPA) announced $44 million in funding to Arizona and Nevada for investment in statewide improvements in local drinking water and wastewater infrastructure and the reduction of water pollution.
“This substantial investment at the federal level helps communities develop the infrastructure needed for clean, safe drinking water and proper wastewater treatment,” said Jared Blumenfeld, regional administrator for the Pacific Southwest for EPA. “EPA is committed to protecting the water resources so important to public health and local economies.”
Contract awarded to help Aguas Andinas bring arsenic levels into compliance with new national standard
In 2005, Chile’s Superintendence of Sanitary Services implemented a new arsenic standard for drinking water, giving the country’s water treatment companies 10 years to accomplish it. Many of the companies, which are privately held, sought solutions for their arsenic issues and help coming into compliance with the new standard. Aguas Andinas, the largest water company in Chile with a customer base of more than 20,000 people, was one of them, putting out a solicitation for technology innovators to provide turnkey proposals for its Lo Pinto well site in the Santiago metropolitan area.
Integrated treatment system helps quickly reduce arsenic levels for Nevada utility
After discovering its three wells contained excessive levels of arsenic, the Spring Creek Utilities Co. hired Sunrise Eng. to help develop a solution. The engineering firm contracted with AdEdge Water Technologies in June 2011 after a competitive bidding process, to design, manufacture and start up an arsenic treatment solution as quickly and economically as possible.
The acquisition enhances the company's food service water treatment offerings
In a strategic move to strengthen and diversify its water treatment brand portfolio, Aquion Inc. announced that it is acquiring Plano, Texas-based Procam Controls Inc., including the OptiPure line of commercial food service products.
It is just unfair to be a germ these days. I hear they have protested on the White House lawn for years, but news crews—citing employer refusal to buy expensive, new magnification lenses—gave no coverage to the microscopic events.
The germs’ issue is that manufacturers have made it way too simple to purify household water, making just about any liquid slurry drinkable. Oh, to be a germ.
