Abstract
Faecal sludge is a source of pollutant that contains solid, organic material, and pathogen microorganism. Faecal sludge sludge has common characteristic such as TSS 4.000-100.000 mg/L, COD 20.000-50.000 mg/L, BOD5 6.000-7.600 mg/L, and total coliforms 105-1010 CFU/100 mL. The biggest amount of organic loading content in faecal sludge might be able to pollute the ground. Therefore waterproof septic tank is one of the solution used in faecal sludge treatment. Septic tank can settleable solid and degrades faecal sludge through anaerobic process. Common characteristic of faecal sludge from septic tank degradation result is TSS 6.000-17.500 mg/L, BOD5 840-2600 mg/L, COD 1.200-7.800 mg/L, and total coliforms 6,3 x 104-6,6 x 105 CFU/100 mL. Drain result of septic tank is treated further in IPLT. Faecal sludge treatment in IPLT is done through physical and biological process. Physical treatment used Solid Separation Chamber (SSC) which separates solid from the faecal sludge. SSC unit is able to remove organic material and pathogen microorganism through settlement, filtration, decantation, and evaporation process. There is no clear SOP regarding sludge drying duration in SSC unit, resulting in inability to determine draining time. The purpose of this study is to determine the removal of TS, TSS, BOD5, COD, and total coliforms in SSC unit and to determine the correlation of total solids and faecal sludge sludge thickness to the removal.
Faecal sludge sample is taken from vacuum trucks which unload in SSC unit of IPLT Keputih. Study is done using batch process with reactor capacity of 16 L, 24 L, and 32 L. Reactor is equipped with ½ inch pipe underdrain to filtration effluent out. Study will start with analysis of effective sludge settlement time and sand media size. Main study uses variation of total solids and sludge thickness. Total solids variations used are 10 g/L, 20 g/L, and 30 g/L, while sludge thickness variations used are 20 cm, 30 cm, and 40 cm. Every reactor with certain variable is processed with upper lid. This study takes 30 days with measurement of temperature and light intensity taken every day. Study is done with duplo principle with following parameters: TS, TSS, BOD5, COD, and total coliforms. TS and TSS analysis is done every day, COD is every other day, and BOD5 and total coliforms is done at the beginning and end of the study.
The result of the study shows that 66,4% water content will be removed during filtration process with optimum removal 97,87% TSS; 99,88% COD; 97,3% TS; 99,71% BOD5; 97,84% Amonium, and 95% Total coliforms. Consentration of Total solids can effect removal TS filtrat meanwhile thickness of sludge can effect removal TS, TSS, and COD filtrat.
