Sureflo design and manufacture
siphon filters (AVGF / SSF) for various water treatment application like
drinking water treatment and water polishing, water treatment for cooling towers.
Sureflo siphon filter uses sand as filtering media and works on the principal of gravity filtration without any valve, pilot mechanisms, rate controllers, gauges and air compressors. The filter has two compartments, filtering section and wash water storage compartment. During normal operation water gets filtered while traveling across the sand bed. During filtration suspended solids gets accumulated in the filter bed and differential pressure start increasing which causes the water level to rise in the backwash pipe. When the water level reaches the top of the loop, siphon action is activated, and the backwashing begins. Wash water flows from the storage compartment through the sand bed and is discharged through the back-wash pipe. A siphon breaker ends the wash cycle.
