Silicon Carbide Ceramic (SIC) Flat Sheet Membrane & Modules for Sandfilter Backwash Water Recovery - Water and Wastewater - Water Treatment

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. 

Key highlights for recovery of Sand filter backwash water using Cembrane:

• No pre-treatment
• 95% recovery rate
• TREATED WATER SUITABLE FOR POTABLE REUSE
• ENERGY CONSUMPTION OF 15-40 WATTS PR. M3
• COMPACT DESIGN BUILT INTO EXISTING CONCRETE STRUCTURE OR IN SKID OR CONTAINERIZED UNIT
