| Summary: | Pollutant load or emission factor from domestic wastewater is a serious environmental
issue that should be evaluated. According to the Ministry of Environment and Forestry,
2017, the largest contributor to BOD pollutant in Citarum watershed comes from domestic
wastewater (62.16%), and the biggest contributor to BOD pollutant in Bandung City is
also domestic waste (94.15%). It is necessary to plan an effective domestic wastewater
treatment system as an effort to prevent contamination to the environment, thus per capita
pollutant loading factor of Bandung City is needed. Seeing that the most widely used
domestic wastewater treatment in Bandung City is On-site Sanitation System (OSS) (38.47%),
and the type of OSS most commonly used is septic tank, this study was conducted to
determine the load factor of fecal sludge from residential area in Bandung City. TSS, COD,
BOD, and Ammonia were tested from 30 samples of fecal sludge. Based on the results of
the study, the range of fecal sludge pollutant load factor in Bandung City is 57.28
g/person/day – 1,064 g/person/day with an average of 546.39 g/person/day, the range for
total COD is 30.06 g /person/day – 294.99 g/person/day with an average of 294.99
g/person/day, the range for total BOD is is 14.05 g/person/day – 504.97 g/person/day with
an average of 175.5 g/person/day, and the range for ammonia is 1.61 g/person/day – 3.11
g/person/day with an average of 2.62 g/person/day. The results from this study are expected
to be used as a base data in preparation of designing domestic sewage treatment
infrastructure, as well as improvement of domestic sewage treatment systems. Additionally,
the pollution load factor is also expected to be used in the calculation of potential polluters,
preparation of city spatial planning and in the study of Water Pollution Control (WPC) policies |
