A solids separator provides a filter in bag form (10) fitted at a tank (11) inlet (14) to pass water, effective to hold sludge pending replacement or cleaning. The bag (10) provides sufficient filter material above a full water line (15) to the storage vessel to enable flow therethrough without unacceptable impedance and sufficient of the solids separator to store build up of sludge to enable a useful period of time between replacement or cleaning. It can be adapted to be removably hung beneath a coarse mesh separator (21) at the inlet (14) to the storage vessel. It can have an outlet to enable cleaning by flushing (41). It may be dimensioned with a length greater than the height of the storage vessel and a substantially uniform diameter there-along. It may comprise a number of separating bags (16, 18, 20) of increasing separative ability, nested, in use, one inside the other.
