Low pressure, high output Aquaray SLP-WW UV systems from Degremont Technologies offer compact and high-efficiency disinfection for wastewater plants with flows from 44 mgd to 615 mgd. Units have computational fluid dynamics (CFD) to ensure accurate flow distribution and minimize head loss. Electronic ballasts power the low-pressure amalgam lamps. Isolated in pure quartz sleeves, the lamps are easily changed when the computer notifies the operator that their 16,000-hour life is over. A sensor monitors UV intensity. An automatic wiper on the reactor cleans the quartz sleeves. The entire lamp assembly removes for maintenance. 804/756-7600; www.degremont-technologies.com.Gas ChlorinatorThe REGAL gas chlorinator from
