A water-filtering method has effectiveness and reduced contamination, and is in particular an ultrafiltration method, and a filtration system contains a plurality of individual filtration modules, each of which is supplied with untreated water via at least one untreated water inlet, and whose filtrate is removed via a filtrate outlet. The filtration modules are backwashed with filtrate, and are divided into groups, wherein during backwashing, each group is individually separated from the untreated water inflow and rinsed with the filtrate that is produced by the remaining groups and fed back during the backwashing.
