Naturalcoagulants can be used in wastewatertreatment for % removal of BOD and %removal of COD. By using moringa seedcoagulant, it showed % removal of BOD of90.12% and % removal of COD in thepharmaceutical industry waste a maximum of71.23%. Through the use of tapioca starchcoagulants, % removal of BOD and CODwas 95.25% and 94.63%. The use of smallcrab chitosan coagulant showed % removalof both BOD and COD’s results was 32%and 31%.
