	The Shape of Things to Come Flow and level experts Krohne have released a white paper detailing results from laboratory testing that show how the company's Waterflux magnetic flow meter is able to perform without any upstream or downstream straight run requirements -- at normal AND low velocities.
	With Thermo Scientific Masterflex Pumps Wastewater Treatment Plants Can Finally Optimize NaOCl Feed Handling chemical oxidants such as sodium hypochlorite or hydrogen peroxide often causes pumping system failures when diaphragm pump technology is used. These failures include vapor-lock, system leaks, unscheduled downtime and poor process performance. These can all lead to expensive overtime r...
	Weigh Scales for Monitoring Chemical Feed in Water & Wastewater Treatment Knowing exactly how much chemical has been fed into your treatment process can help you comply with regulations, run a more efficient chemical feed system and improve operator safety. This white paper discusses the different traditional ways of monitoring the amount of chemical used, why to...
	Lean Water Operations: Controlling the Cost and Pricing of Water While Improving Efficiency. A Real World View From United Water In today’s environment, we all need to find ways to do more with less. We need to be more efficient and accountable. One way the water and wastewater industries have achieved that is by adopting lean principles – leveraging new technology and processes to modernize the industry. United Water has ...
	Reducing electrical grid-powered aeration use and costs in reactor basins Electrical aeration is used intensively in reactor basins at activated-sludge wastewater treatment plants to supply the mixing and oxygenation needed for digestion. Officials at Eden, North Carolina, investigated the ability of solar-powered circulation technology (SPC) to reduce their operationa...
	Economical, efficient and effective mixing: Three approaches to controlling odor in wastewater treatment ponds Long-distance circulators (or mixers) have emerged as an economical, effective solution for controlling odors in many wastewater ponds. Long distance circulators are different from any other reservoir equipment: The adjustable intake takes advantage of the manner in which water forms thin horizon...
	ANDalyze - A Breakthrough in Water Testing Technology - Powered by DNA ANDalyze has developed a series of products for testing water contamination using catalytic DNA technologies. This technology and product is a universal platform that offers simple, fast, inexpensive and reliable detection of trace metals and other target chemicals. This whitepaper co...
	Quality of Washed & Compacted Screenings The finer the screens, the more screenings and organics are removed from wastewater. Typical solids content of raw screenings ranges from 10 to 15 % DS. Fecal matter in the screenings is odorous, attracts pathogen vectors and contains much water. Fecal matter should be washed out of the screening...
