This work attempted to determine the optimum conditions required for the coagulation and ,flocculation process, as an essential stage of the ,ceramic wastewater, treatment. Coagulation and ,flocculation, is a very necessary step in industries as it lessens turbidity, color, and odor of ,wastewater,. The experimental work was performed in several runs.

Among these technologies, flocculation that includes coagulation/flocculation, and direct flocculation is an effective and easily applied method in the removal of insoluble particles from wastewaters (Bolto and Gregory 2007; Teh et al. 2016). Flocculation removes organic compounds along with suspended solids and also decolorizes waste streams.
