Effluent decolorizing flocculent is used for effective removal of colors for waste water produced in dyestuff plants. Cationic by nature, offered flocculent promotes sediment formation of suspended color and solids from handled waste water. Offered flocculent is also effective in supporting chemical oxygen demand of treated waste water. Its dosage depends on the quantity of treated effluent. Available in liquid form, effluent decolorizing flocculent is non toxic by composition and it readily dissolves in water. Before its application, ph value of waste water needs to be adjusted to get the desired result.
