Trojan Technologies has introduced drinking water UV systems validated to fully comply with U.S. federal regulations for delivering 4-log inactivation of viruses, including the highly resistant adenovirus. Four units from the expanded TrojanUVSwift ™ SC product line, including the new D03 and D18 models, now offer third-party-witnessed validation to meet all the recommendations of the EPA UV Disinfection Guidance Manual and, for the first time, allows water providers to implement a fully compliant single-unit UV solution for the maximum required treatment of viruses. Designed to meet the needs of large and small communities, the system incorporates energy-efficient, low-pressure high-output UV lamps.

SolarBee was selected to demonstrate its new THM Removal System at the New Product Technology Showcase during the American Water Works Association’s 2011 Annual Conference and Exhibition. The system combines the latest mixing and air-stripping technologies to remove all four types of regulated trihalomethanes (THMs) from potable-water storage tanks. It helps municipalities comply with the 80 µg/L locational running annual average limit specified in the EPA Stage 2 Disinfectants and Disinfection Byproducts Rule.

Compressible media filter

Pennwell web 250 188

The WWETCO FlexFilter™ is suited for use in CSO, primary treatment, tertiary treatment and industrial water pretreatment. The system uses a synthetic compressible media to capture solids in a high rate filtration process. The influent liquid applies a hydrostatic force to a flexible bladder causing the media to compress. The tapered compression provides for a densely compacted media bed at the bottom of the filter that graduates to an expanded bed toward the surface. The simple gravity system has no moving parts.

Stormwater management

Pennwell web 250 73

Oldcastle Precast’s patent pending Storm Capture modular stormwater detention system is an underground structural precast concrete system for stormwater management. It can be used for infiltration, detention, or retention and reuse, as well as for treatment-train systems. The system features a stand-alone, traffic bearing design which does not rely on final paving and associated stone underlayment, or on specific stone backfill for structural capacity and storage. The modules are constructed of high-strength concrete and are installed on a simple setting bed of stone that is up to 20% less than other systems.
