Grit removal, processing and handling is another area where wastewater treatment plants can improve savings. If allowed to enter the plant, grit will clog systems – reducing efficiency and cause abrasion damage which can prematurely wear down pumps and valves. This all adds to operations and maintenance overhead. Choosing the correct grit trap, classifier and washer can considerably cut down on costs.
Hydro-Dyne’s grit dewatering equipment, the Sand Shark Grit Classifier and Sand Shark Hydro-Cyclone have been specifically designed to dewater grit slurry from wastewater. This grit removal and dewatering technology is compact, flexible, has a small footprint and can be retrofitted and customised to site conditions.
Features
Mounted directly over the Sand Shark Grit Classifier inlet hopper, the Sand Shark Hydro-Cyclone has replaceable wear liner and no moving parts. This grit removal and dewatering technology features:
High capture efficiency — lamella trays and centrifugal force handle peak grit events
Grit removal capacity of 95% of 75 micron particles (2.65 g/cc) at average flow
Durable 304 or 316 stainless steel.
Lower bearing fully protected against ingress of abrasive particles
Dewatered grit is deposited directly into the receptacle.
