Turning Backwash into a Recovery Engine
The challenge
Backwash from groundwater treatment is typically dischargedvas waste. It carries high loads of iron, manganese, andvsuspended solids that rapidly foul conventional polymeric UF, driving down recovery, increasing liquid waste volumes, and keeping utilities from closing the water loop.
The solution
At Vitens, a compact ceramic UF system turns backwash water into a recoverable resource. Built to tolerate dense, metalladen streams and frequent cleaning, it delivers consistently clear filtrate with low energy and maintenance – enabling a near-ZLD recovery loop within the utility.
