The researchers tested a system using membranes to clean water from swimming pool backwash. They used two ultrafiltration stages and a nanofiltration stage. The first stage reduced pollutants before the second stage, which kept the water clear and low in organic carbon. The nanofiltration stage further cleaned the water, making it safe to return to the pool.
