Spectrus TD1100E is a non-oxidizing microbiological control agent used to kill or control growth of microbial populations in open evaporative cooling systems. It is designed to reduce microbiologically influenced corrosion and the potential risk of Legionella bacteria, helping avoid damage to equipment and keeping system inefficiencies at bay. A decreased use of chemicals lowers environmental impact.

Tackling Arsenic With Adsorption

Supai, Ariz., is the capital of the Havasupai Indian Reservation in the western Grand Canyon. The reservation is the site of some of the country’s most beautiful waterfalls and is a popular destination for hikers and backpackers. In fact, hiking is one of the few ways to reach Supai, which is the only place in the U.S. where mail is still delivered by mules. The nearest surfaced road is 9 miles away.

Heavy Paper

The pulp and paper industry is one of the heaviest users of water within the North American industrial economy, requiring an average of 54 cu meters of water per metric ton of finished product. As water is used in nearly every part of the manufacturing process, accumulation of scale is a phenomenon that can occur in all pulp and paper making processes. This occurs even with the purest water and state-of-the art water treatment.

A Ph.D. student's research may save lives

A "super detector" that can track the traces of a lump of sugar in the Baltic Sea was the starting point for a potentially life-saving technique developed at Lund University in Sweden. The method detects toxic algae blooms in drinking water.

A biosensor recently developed at Lund University can detect substances at 10,000 times lower concentrations than what is currently possible. PhD student Lesedi Lebogang found a practical application that could be particularly helpful in warm climates such as Africa, Australia and the southern U.S.
