To separate solid particles from liquids or gas, the liquid or the gas is passed through a coil, formed from one or more threads wound on a carrier. After subsequent washing and drying, the solid which has been filtered out during the filtration process is removed by unwinding the coil from the carrier, the latter consisting of a permeable hollow cylinder closed at both end faces by means of end plates, and provided with a feed orifice.
