A screw press inlet section comprises a housing defining a radial inlet opening leading to an axially extending chamber through which a screw is rotatably mounted for conveying and dewatering a solid-liquid mixture fed into the chamber through the inlet opening. The housing has an end wall extending in a plane normal to the screw and to which a perforated plate is integrated to provide the additional surface available for drainage at the inlet section. A pulsator is provided within the housing to generate hydraulic pulses against the perforated plate so as to prevent plugging thereof.
