FIELD: module-type filtering systems. SUBSTANCE: filtering system includes technological modules 305 mechanically interconnected and provided with filters hydraulically interconnected in parallel. Each technological module may contain not only filter 314 but flow-through passages 334A, 334B and 334C for starting liquid, waste liquid and product respectively so that several interconnected modules may be mounted and dismantle as single unit which is easy-to-get-at. It is supposed that interconnected modules may be located at rational use of space, for example, by introducing into deep or not so deep well, column, along surface of ground. Adjacent technological modules may be interconnected by means of telescopic joint or may be kept in connected position by connecting them to ropes or rods. EFFECT: rational use of space; enhanced efficiency of filtering. 10 cl, 4 dwg
