SANDFILTER BACKWASH WATER RECOVERY

To maintain design capacity of Sand filters, they need to be backwashed periodically with treated water. Globally, upwards of 10% of all treated water is used for backwashing.

This water contains high amounts of suspended solids, bacteria, parasites & heavy metals and is typically sent wholly or partly to the raw water intake of the plant. This creates risk of upsetting treatment process and affecting the final water quality.

Although filter backwash wastewater contains suspended solids in the hundreds of mg/l and turbidities exceeding 1000 NTU, our SiCBlox modules can directly treat and reuse the wastewater for potable reuse.
