Abstract

Domestic wastewater pollution is one of the reasons for the decline in the national Water Quality Index. The increasing number of people with inadequate sanitation facilities requires a solution. Porous concrete with RCA aggregate has the potential to improve domestic wastewater. Made of porous concrete, the filter is made with dimensions of 40×40×5 cm3 using RCA aggregate with 0.5-2.0 cm gradation. Two reactor models of the same size were prepared, containing 3 and 4 layers of filters. Domestic wastewater as a test object comes from Tlogomas Integrated Sewer System, flowed continuously into the model. The results of Test 1 show that the 3-Filters Reactor Model can improve the pH and COD values according to the quality standard, while the 4-Filters Reactor Model can only improve the pH value. The results of Test 2 show that the 3-Filters Reactor Model can improve the pH and TSS values according to the quality standard, while the 4-Filters Reactor Model can only improve the pH value. The average efficiency of the filtration against influent shows that the 3-Filters Reactor Model is better than the 4-Filters Reactor Model with the percentage of improvement in pH 11.54%, BOD 26.15%, COD 20.79%, and TSS 46.37%. However, in sediment trapping, the 4-Filters Reactor Model is superior with 112 mm compared to the 3-Filters Reactor Model which is 100.5 mm.
