Design of Wastewater Treatment Plant by Using Anaerobic Filter Process on Five Stars Hotel in Surabaya

Abstract

Surabaya, Indonesia's second largest city and the capital of East Java Province, has been one of the most important and busiest trading city ports in Asia. As its potential, facility and geography advantages, Surabaya has great economical potential as example hotel is one of the most rapidly growth business in Surabaya. Hotel is a commercial establishment providing lodging, meals, and other guest services. By the existence of facility and human activity, hotel produced waste such as wastewater and solid waste. Hotel wastewater produced from hotel activity sourced from cooking residue, restroom, spa, swimming pool, and etc. In this study, wastewater produced is treated by wastewater treatment with anaerobic filter as the alternative. The parameters of wastewater used are COD, BOD, TSS and oil and grease. Characteristic of wastewater is based on secondary data from earlier experimental studies with five stars hotel as the objects. Calculation of dimension based on DEWATS module. According to the results of calculation, Anaerobic Filter is designed with 1 septic tank and 8 compartments. The dimension of Anaerobic Filter is 16m x 4,5m x 2,5m within dimension of septic tank is 6m x 4,5m x 2,5m; dimension of each compartments are 2m x 4,5m x 2,5m.
