What is Solid Liquid Separation

Solid-liquid separation is the process of separating two phases, solid and liquid, from a mixture. This separation is typically performed in order to recover the solid phase for further processing or reuse, or to clarify the liquid phase for discharge or reuse.

There are several methods of solid-liquid separation, including filtration, settling, centrifugation, and evaporation. Filtration involves passing a mixture through a filter medium that retains the solid phase while allowing the liquid phase to pass through. Settling involves allowing the mixture to stand undisturbed, causing the solid phase to settle to the bottom, while the liquid phase remains on top. Centrifugation involves spinning the mixture in a centrifuge, resulting in the solid phase settling to the bottom due to centrifugal force. Evaporation involves heating the mixture to evaporate the liquid phase, leaving behind the solid phase.

Solid-liquid separation is used in many industries, including wastewater treatment, mining, food and beverage processing, pharmaceuticals, and many others.
