Filtration is the primary process used for the removal of suspended solids in wastewater. This technique involves passing wastewater through a porous material or medium that allows water to flow while trapping particles, solid debris, and other contaminants. This is essential for improving water quality and ensuring that harmful substances are removed before the water is treated further or discharged.

While coagulation is often a prior step in the treatment process, it primarily alters the characteristics of suspended solids to facilitate their removal by sedimentation or filtration. Centrifugation can also be employed to separate solids from liquids based on density; however, it is less commonly used in conventional wastewater treatment compared to filtration. Disinfection is associated with eliminating pathogens and does not target suspended solids specifically. Therefore, filtration stands out as the most direct and commonly applied method for effectively removing suspended solids in wastewater treatment.
