Suspended solids including fine particles and colloids cannot be removed efficiently with gravitation sedimentation ; they are removed using centrifuge , dissolved air flotation , diatomaceous earth filtration , coagulation sedimentation plus rapid sand filtration while dissolved solids are removed with ion exchange , ultrafiltration , activated carbon adsorption and chemical oxidation 悬浮固体之去除包括微颗粒及胶体物，无法以重力沉淀之物质，可采用离心分离机、空气浮除法、矽藻土过滤法、混凝沉淀加快滤池等去除之。而溶解性固体去除则采用离子交换法、微细孔滤膜过滤、活性碳吸附以及化学氧化等去除之。
