HydroGlobe offers the ActivMet™ system, a proprietary, mechanically activated filtration system that provides a continuous source of active iron reaction sites for adsorbing and/or reacting with arsenic and other heavy metals including lead, copper, chromium, mercury, depleted uranium, and others. The system was installed in Hopewell, NJ. In tests completed in January, the system, which consists of filtration tanks, pumps and an iron-based chemical added to the water stream, cut arsenic at a local well from more than 40 ppb to fewer than five.

The Leopold Type S® Technology Underdrains are the latest in the company's line of filter equipment for the water treatment industry. Both the Type S® and Type SL® Underdrain employ a unique water recovery channel for enhanced air scouring and water backwash performance. Other results of Type S technology are broader air flow range, improved air stability under all operating conditions and lower water maldistribution. The Type S underdrain is ideal for installations requiring longer laterals, while the Type SL Underdrain features a lower profile (4'' lower) making it ideal for shallow filters where greater filter media depth is desired.

Mixed oxidants

Th 149614

TTHM and HAA5 regulatory limits are driving water treatment facilities to look for alternative means of disinfection that avoid the production of disinfection by-products (DBPs). Replacing chlorine with MIOX mixed oxidants can reduce DBP formation by up to 50%, while still leaving a durable free chlorine residual, even when long detention times are an issue. TTHM reductions tied to MIOX systems are three-fold.

USFilter has expanded the offering for their its GFH™ arsenic removal systems. Communities now have the option of media change out services, equipment leasing or capital purchase. The systems remove arsenic through an adsorption process. Operated as fixed-bed absorbers, operator attention is minimized through infrequent need for backwash and elimination of pre-oxidation. Once the adsorption capacity is reached, the media is removed and replaced with new media.

The U.S. EPA recently released data generated during a third-party evaluation of eight commercially available rapid toxicology technologies. The data, posted to www.epa.gov/evt, confirm that the ToxTrak™ Toxicity Test from Hach yields screening performance that can be effective and practical in early warning water surveillance for chemical contaminants. Battelle and the Environmental Technology Verification Program completed this evaluation under a cooperative agreement with the USEPA.

The new Omexell™ double-walled, PVDF hollow fiber UF membrane has a nominal pore diameter of 0.01µm, allowing for the removal of all particulate matter, bacteria (9-log reduction) and most viruses and colloids and is resistant to strong levels of disinfectants (up to 2000 ppm NaOCl). Despite the small pore diameter, the membrane has a very high porosity resulting in a flux similar to that of microfiltration (MF) and can effectively replace MF in most cases.

Bermad manufactures a wide range of control valves that can be readily applied to filter control and backwash operations. Included in this range is the 3-ported 350 Series specifically designed for filter backwash applications. The heart of the series is a diaphragm actuated plug assembly that keeps the supply port closed until the backwash port is opened and vice-versa. This prevents the mixing of supply and wastewater.
