With respect to TSS remained in wastewater effluents, several methods can be recommended for treatment. Natural processes are specifically recommended for algae removal from the effluents of stabilization ponds and lagoons. Examples are:
Rock filter, intermittent sand filter, floating aquatic plants (Eichhornia crassipes), constructed wetlands subsurface flow system (Typha Sp.), overland flow and electrolytic method (1, 2). The use of electro-coagulation techniques is also developed for final polishing of effluents from these systems and it may be proposed for removal of algae too
