Abstract

The abundant supply of greywater as domestic waste becomes an opportunity for further processing and can be reused as water (reuse) instead of consumption (eating and drinking). Every day as much as 60% of greywater is wasted as a by-product of human consumption. Filtration using local media becomes the treatment option. The size of the greywater particles ranges from 10 μm to 100 μm. The filter media size is made into two levels i.e., 80 mesh (active zeolite and charcoal) and mesh 18 (active sand) to filter particles by ten μm and mesh 14 (zeolite and activated charcoal) and mesh 10 (activated sand) to filter the particle size of 53 μm. The combination of filter media thickness in three experiments took one of the filter media to be used in each experiment. Each experiment will be used one filter media with a thickness of 50 cm and 25 cm each for supporting filter media, with a total media thickness of 100 cm.All of the above become independent variables in research. While the dependent variable is water quality standard in accordance PP. 82 the year 2001 with the main parameters are BOD, COD, TSS, pH, and detergent. The flow rate is set at 24.55 ml / m2 min. Besides the quality standard, the research still refers to cost efficiency and processing time (filtration). All variables consist of 6 filters that give different results; in laboratory test control, only pH fulfills the quality standard of PP. 82 of 2001. This study provides the best combination of filter media in A filter with BOD presentation: 82%, COD: 85%, TSS: 99%, and 98% detergent with the fastest contact time of 2700 seconds. The resulting effluent placed TSS and detergent parameters below the quality standard threshold with TSS values ranging from 15-24 mg / l, while the detergent content was in the range of 14.828 - 42.37 mg / l.

Abstract

Liquid waste produced from the tofu industry contains high contaminants such as BOD, COD, TDS, pH, and TSS, which can pollute the environment. Therefore, pollutants should be decreased before being discharged into the environment. Tofu waste treatment is constrained by adequate technology and high costs. Biological treatment is one of the best treatments, a waste treatment process by utilizing microorganisms. This research used the intermittent anaerobic-aerobic process and was conducted on a laboratory scale using a tank made of glass 25 cm long, 20 cm wide, 15 cm high, and a tank of 30 cm long and 15 cm wide 15 cm high. The treatment process in this research used samples adding EM4 solution with a concentration of 1/20 and samples without EM4. The stages of the research were carried out consisting of preliminary research, core research, and further research. Preliminary research used 1/20 (5%) concentration of EM4 and was fermented for four days at room temperature. As a result, the pH value decreased from 6 to 4, and the presence of a white layer above the surface. The average pollutant reduction efficiency value in the sample with Effective Microorganism-4 (EM4) and without the Effective Microorganism-4 (EM4) was tested at different duration times for each parameter. The efficiency reduction value of the sample with EM4 of BOD was 87.14%, COD 74.68%, TSS 15.88%, and TDS -17.91%, while in the sample without EM4 of BOD value was 76.54%, COD 67.78%, TSS 22.77%, TDS -16.78% with a time process of 41st day.
