Before waste water can be recycled it must be appropriately treated for be compatible with the environmental concern s(soil, plants, natural water effuents etc.).  This paper presents a new solution for chemical waste water treatment. This solution is based on the controlled addition of two components during wastewater treatment (Waste Water Clarifleir - WWC and Waste Water Intensifier - WWI). These components neither water soluble nor hazardous and serves as a nucleating site to create larger and denser flocons. Through careful dosage study in relation to the influent wastewater flow rate, pH and demand biological oxygen levels (BOD), optium usage amounts were established. Since every influent stream is unique, the end user was ultimately determined the best dosage of WWC and WWI for that facility. The new solution does not result in any toxic waste or hazardous clean up. The resulting sludge has no residual toxic by-products and can be spread back into the soil as a fertilizer.
