Water filtration in public swimming pools: ANSES publishes its recommendations on membrane processes
There are several techniques for filtering pool water, including diatomite filters, glass bead filters, sand filters or membrane processes.
Sand filtration is currently the most widely used water filtration process in French public swimming pools. However, when used alone, this technique cannot always meet the regulatory limits for water quality. To achieve this, therefore, operators increase the rate of water renewal in the pools.
Membrane filtration is a physical separation process using a membrane that is both permeable and selective. Depending on its intrinsic characteristics and the way in which it is used, the membrane constitutes a barrier allowing the transfer or retention of certain compounds.
