EN 16713-1:2016 (E) 5 Introduction The filtration system in any swimming pool is there to remove the suspended matter from the pool water. Filtration is achieved by passing the water through a suitable medium contained in a filter body. It is generally accepted that there are four types of filters associated with swimming pools: a) pre-coat filtration/diatomaceous earth (DE); b) disposable cartridge or filter bag; c) graded aggregate (single/multi-layer-filter); d) other filters (e.g. membrane systems).
