The Neptune Benson family of ultraviolet (UV) systems has been third-party tested at a California wastewater plant in accordance with the Ultraviolet Disinfection Guidelines for Water Reuse Third Edition (National Water Research Institute/Water Research Foundation, August 2012). The units were designed using a variety of CFD emulation tools and are 800-watt, low-pressure, high-output, closed-vessel systems designed for high-level reuse water disinfection. The NWRI standard allows municipal wastewater to be treated and reused for various applications.

The Cretex PRO-RING™ manhole grade adjustment system is a lightweight alternative to concrete grade rings or brick and mortar used in the construction of manholes and other utility structures. PRO-RING is made from expanded polypropylene, a high-strength, impact-absorbing plastic that meets AASHTO HS-25 load requirements. PRO-RING also meets the requirements of ASTM C969 (exfiltration test) and C1244 (vacuum test), has excellent chemical resistance, and is approximately 1/20th the weight of concrete grade rings.

With Mazzei's patented AirJection® Wastewater Aeration technology, wastewater is recirculated from activated sludge or sludge digester basins through high-efficiency Mazzei injectors to draw in air or concentrated oxygen and dissolve it into the wastewater. No blowers are required. The resulting gas-water mixture is returned to the basin through Mazzei Mass Transfer Multiplier™ (MTM) Nozzles for greater oxygen transfer and basin mixing.
