Abstract

The coffee effluent was collected from the dumping site of coffee effluent from the coffee industry to analyze the physico-chemical parameters of effluent using standard methods. The effluent from coffee industry had high value of the physical parameters such as total hardness, turbidity and electrical conductivity. The chemical parameters such as calcium, potassium, nitrate, dissolved oxygen were higher in effluent before and lowered after the treatment. The effluent from the coffee industry was the major source of pollution which will affect the flora and fauna existing in that dumping environment. Tomato plant growth signifies the dilution of effluent promotes the growth of the stem. Hence, a special care is needed for complete treatment of coffee effluent before they are discharged into the environment.
