The core benefit of HYBACS™（Hybrid Active Sluge） is that it enables an existing activated sludge process to be swiftly upgraded for increased capacity or performance, by simple offline installation of SMARTTM units. Without increasing the volume of the aeration tank, the existing capacity can be increased by 50-150%, the total investment can be saved by 30%, and the sludge settling performance can be significantly improved.

Especially suitable for deep phosphorus removal in sewage treatment. The total phosphorus content of effluent can reach 0.5mg/l with single point dosing, and the total phosphorus content of effluent can reach 0.1mg/l with multi-point dosing. The suspended solids concentration can be under 5mg/l.

Purac air flotation filter is a mature technology that can be used for surface water treatment and sewage deep treatment. Flofilter is a compact and efficient plant as it combines flotation and filtration in one treatment basin.

Purac Dissolved Air Flotation technique is an effective and rapid method for separation of particles from water and wastewater, developed and refined since 1950s.
