Abstract :
This design case presents a conceptual effluent treatment plant (ETP) for a facility that combines edible-oil
refining, soap and detergent manufacture, margarine or shortening production, and personal-care formulation. A nominal
wastewater flow of 60 kL/d is used as the project basis. The proposed configuration is source segregation; screening and oil
separation; equalization and pH control; coagulation-flocculation and dissolved-air flotation (DAF); biological treatment;
clarification and filtration; and, where a validated reuse case exists, membrane polishing or reverse osmosis (RO). The
design is deliberately presented as conceptual. The values in this document are assumptions for feasibility assessment, not
guaranteed performance values or construction dimensions. Final design requires site sampling, treatability trials, hydraulic
profiling, civil design, equipment-vendor data and approval by the relevant regulatory authority.
