Gravity Sand Filters are fully automatic without mechanical componentry and operate on a combination of gravity and hydrostatic heads, capacities from 6.5 cu/mt/hr to 640 cu/mt/hr.
Pressurised machines are also fully automatic and employ electrical pressure monitoring and auto sequencing valves for backwash and rinse cycles, capacities up to 70 m2 in one unit.
Gravity Sand Filters are a cost effective way of improving final effluent quality. The filter requires no controls and has no moving parts such as pumps, valves, flowmeters or indicators, but can automatically backwash and rinse triggered on differential pressure alone.
They are supplied in varying diameters to suit required flowrate Filtration quality to 0-3mg/l SS Minimal head loss through filter bed 120-150 mbar
