A screw press is a mechanical device used for dewatering and extracting liquids from solid materials. In brief, its working involves feeding a mixture of solids and liquids into a cylindrical screw or auger. As the screw rotates, it applies pressure to the material,
compressing it and separating the liquid phase from the solid phase. The compressed material moves along the screw, and as it progresses, the pressure increases, leading to further dewatering. Eventually, the separated liquid is expelled through openings in the
press, leaving behind drier solids. Screw presses find applications in various industries, including wastewater treatment,
food processing, and more.
