The process of removing suspended solids from water or waste water.
 
Generally, sieving or sedimentation method is used to remove solids from wastewater. Sludge treatment The separation methods used in are sludge gravity concentration, sludge flotation or sludge mechanical dewatering. Water treatment includes microfiltration, clarification and deep bed filtration.
 
The process of separating solid from liquid is Solid-liquid separation , many methods, sedimentation, filtration, membrane filtration, pressure filtration, vacuum, Centrifuge ......
 
　　 Solid liquid separator It is a machine that uses centrifugal force to separate solid particles and flocs in liquid.
 
essential information
 
, mainly introduces the properties of solid particles, liquid and solid-liquid suspension system; Filtration theory and practice, sedimentation separation theory and practice; Hydrocyclone, liquid-solid fluidized bed, etc Solid liquid separation equipment The theory and practice of; Amplification rules and methods of solid-liquid separation.
 
The content of this book collects the author's experience in the design, production and experiment of solid-liquid separation in the field of hydrometallurgy for many years, as well as in the solid-liquid separation work in the fields of chemical industry, light industry and biochemical industry, and also absorbs the latest achievements in this field made by experts at home and abroad in recent years.
 
This book can be used as a reference book for hydrometallurgy workers, as well as for scientific and technological personnel engaged in metallurgy, chemical industry, light industry, biochemistry and other fields, and teachers and students of relevant majors in colleges and universities.
