The development of culinary business at Culinary Tourism Centre (CTC) has produced domestic wastewater from dish washing activities and food residues. One CTC in Tambaksari District, Surabaya City has not had Wastewater Treatment Plant (WWTP) yet. The CTC only has equalization tank for accommodating wastewater before discharged into the water body. This research aimed to determine the characteristics of domestic wastewater from the CTC and to design the appropriate WWTP in the CTC. The standard was based on the Regulation of the East Java Governor Number 72 Year 2013. The result showed that the concentrations of TSS, grease and oil, BOD, COD were 14 mg/L, 1.59 mg/L, 1154.8 mg/L, and 2054.8 mg/L, respectively. The WWTP units consisted of a grease trap, an equalization tank, primary sedimentation tank, anaerobic tank, aerobic tank, and secondary sedimentation tank. The estimated cost to build the WWTP was IDR 278,093,774.

Abstract:Phosphorus is a major substance that is needed especially for agricultural production or for the industry. At the same time it is an important component of wastewater. At present, the waste management priority is recycling and this requirement is also transferred to wastewater treatment plants. Substances in wastewater can be recovered and utilized. In Europe (in Germany and Austria already legally binding), access to phosphorus-containing sewage treatment is changing. This paper dealt with the issue of phosphorus on the sewage treatment plant in Nitra. There are several industrial areas in Nitra where record major producers in phosphorus production in sewage. The new wastewater treatment plant is built as a mechanicalbiological wastewater treatment plant with simultaneous nitrification and denitrification, sludge regeneration, an anaerobic zone for biological phosphorus removal at the beginning of the process and chemical phosphorus precipitation. The sludge management is anaerobic sludge stabilization with heating and mechanical dewatering of stabilized sludge and gas management. The aim of the work was to document the phosphorus balance in all parts of the wastewater treatment plant - from the inflow of raw water to the outflow of purified water and the production of excess sludge. Balancing quantities in the wastewater treatment plant treatment processes provide information where efficient phosphorus recovery could be possible. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. The mean daily value of P tot is approximately 122.3 kg/day of these two sources. There are also two outflows - drainage of cleaned water to the recipient - the river Nitra - 9.9 kg Ptot/day and Ptot content in sewage sludge - about 120.3 kg Ptot/day - total 130.2 kg Ptot/day.
