Abstract

Tofu is a food that is often consumed in Indonesia. Every 100 g of tofu contains macronutrients such as 7.8 g protein, 4.6 g fat, and 1.6 g carbohydrates. Tofu also contains micronutrients like phosphorus, potassium, calcium, vitamin B, and vitamin E. The process of making tofu produces liquid waste. Based on one of the tofu factories in Indonesia the qualities of COD, BOD, and Total Coliform are 5964.48 mg/L, 734.1 mg/L, and 59.13 MPN/100 mL. The purpose of this study is to obtain the unit dimensions of the tofu wastewater treatment system using the ozonation method so that the water released will meet the available quality standards. The research was carried out by studying the liquid waste treatment using the ozonation method until the wastewater treatment system was obtained and then calculating the effluent of the system design. Based on the calculation results, the dimensions of the tank are cylindrical and the units can be determined. The treatment system able to reduce COD, BOD, and TC with the qualities of system are 178.67 mg/L, 24 mg/L, and 0 MPN/100 mL, which values are meet quality standards so that they can be released into the environment.
