PERANCANGAN BANGUNAN PENGOLAHAN AIR LIMBAH DOMESTIK GREY WATER MENGGUNAKAN ABR DI PERUMAHAN DARUSSALAM PERMATA

Abstract

The population of Kubu Raya Regency in 2020 is 609,392 people. This will have a major impact on various sectors, especially housing and settlements. The population density in Kubu Raya Regency will continue increased every year in line with investment that continues to grow in various sectors. The increasing number of residential wastewater that needs to be treated before being discharged into water bodies is one of the impacts of an increase in population. Based on problem Therefore, it is necessary to design a domestic wastewater treatment plant to improve the quality of sanitation in Darussalam Permata Housing Complex. The purpose of this design is to obtain a domestic wastewater treatment design grey water useAnaerobic Baffled Reactor (ABR) in community settlements where this research was conducted at Darussalam Permata Housing Complex. The research was conducted by calculating the dimensional design and efficiency of the ABR unit wastewater treatment plant using population data, discharge and wastewater characteristics. Based on the results of the calculations that have been carried out, it is obtained a detailed design of the ABR unit wastewater treatment plant which includes the dimensions of the settling tank (1.5 m× 3 m × 1.8 m) and compartment dimensions (0.9 m× 1,11 m × 1.8 m) which consists of six compartments, while the processing efficiency in the settling tub is 30% COD, 32% BOD, and 68% TSS. Then the processing efficiency in the compartment is the COD parameter of 92%, BOD of 94%, and TSS of 60%.
