Description

​The Hydro-Clear® pulsed-bed sand filtration system is an excellent solution when gravity filtration is needed. It features a unique underdrain system and a shallow bed of mono-media, fine-grained sand, a design which permits the filter media to be “pulsed” periodically as solids build up. Filter runs are extended and the filter is automatically kept on-line, despite varying loads, and changing water characteristics

The pulsed bed, gravity flow Hydro-Clear filter was designed specifically to remove suspended particles and turbidity from wastewater treatment plant effluent. Designed to work around the clock, the Hydro-Clear filter provides unequaled efficiency, combined with the experience to keep your plant compliant 24/7/365.

Hydro-Clear® Sand Filtration Systems

Evoqua's Hydro-Clear® Sand Filter is a pulsed-bed filtration process designed to remove suspended solids (TSS) and turbidity (NTU) from municipal and industrial wastewater effluent. The long-term reliability of this process is evident in the hundreds of systems in operation for more than 40 years with treatment capacities from 10 gallons per day (GPD) to 130 million gallons per day (MGD).
