STUDI PERENCANAAN BANGUNAN PENGOLAHAN AIR LIMBAH INDUSTRY LAUNDRY JOYO SARI, KOTA MALANG DENGAN SYSTEM PROSES ANAEROBIC FILTER

Abstract

Increased human growth has greatly influenced the growth of service industries, such as the laundry industry. Then, the laundry industry can produce a lot of liquid waste because of the use of materials such as detergents that trigger environmental pollution. Therefore it should be done by planning an alternative WWTP with an anaerobic filter on the laundry. In this study samples of waste water were taken from D'star laundry, EL laundries and Fortuna Laundry JL. JoyoSari, Malang. This analysis is done to calculate the BOD, COD, and TSS values used in the design of wastewater treatment plants. It is expected that the WWTP planned outlets will meet the established standard of wastewater quality. Baku quality of water is obtained from Governor of East Java Regulations No. 72 of 2013. D'Star Laundry, EL Laundries and Fortuna Laundri's large wastewater discharge was 18.8 m3/day. The water quality of each laundry has been sampled on the perum Service is more than the standard Quality Wastewater, with the number of parameters values are BOD = 290,02mg/L, COD = 867,2mg / L, TSS = 218,7mg/ L. From these results planned treatment of WWTP that includes equalization tub, anaerobic tub and polishing tub, until obtained parameters that correspond to standard waste water quality and can determine the design planning and budget plan of cost of development WWTP.
