The hydraulic differential approach is the key to the success of Enviroquip''''s SS Series clarifiers. This process assures that activated sludge is dense, fresh and spends minimum time outside of the aeration process.
Sludge is drawn from the floor of the basin to a suspended trough for removal by an artificially create hydraulic differential. Since the trough is open, it allows visual inspection of the sludge from all pickup locations. The tubes can be cleaned with a straight rod or hose from above without exposing the operator to danger or removing the unit from service. A low head loss transfer of return activated sludge is provided.
Truly non-clogging
Eliminates bent tubes or underwater orifices
Same length draw tubes eliminate flow control devices and provides balanced sludge removal
Open troughs allow viewing of sludge return from each tube to ensure required pumping rates
95% of scum is removed inside the influent well. SS3.5 with optional ScumTrappR
Center pier design provides versatility
Flocculating inlet wells improve clarifier performance
Available in galvanized mild steel or type 316 stainless steel
The sludge suction tubes are large, typically four inches in diameter, with no orifices. Since the tubes are large and straight, the potential for clogging is minimized.
Squeegees rake sludge to each riser tube location. Their raking pattern is designed to cover any given part of the floor twice per revolution.
All models are fitted with spray scum traps which improve the full surface skimming ability of the units. Scum ports situated within the influent well remove a major portion of the scum before it enters the clarifier. Additional ports at intervals across the clarifier scum trough remove the remainder of the scum. All units are built with access bridges, which make it easy to maintain the drive assembly and allow easier cleaning of the return trough, and pickup tubes.
