SEPTICTANK PERESAPAN SISTEM KANAL (PERSIKAN) SEBAGAI TEKNOLOGI ALTERNATIF PENGENDALIAN PENCEMARAN KOLIFORM TINJA PADA PEMUKIMAN PADAT
Abstract: The main problem of
domestic wastewater treatment in term of bacterial removal using conventional
septictank in many developed towns is lack of land to purify domestic sewage
into 10 m minimum safety distance according to WHO regulation. It is necessary
to develop new treatment system to ensure bacterial will be removed 100 percent
less than 10 m distance. Channel System Filter Septictank (CSF Septictank) is
designed to solve the problem above. CSF Septictank is a common septictank
equipped with filter tank separated by several partition walls to shape
channels. CSF will consist of three parts: initial storage tank, filter tank
and final storage tank. The Filter tank is fully filled with fine sand as
filter medium. Wastewater will flows from the initial storage tank then pass
the filter tank and entering the final storage tank as product of CSF
Septictank treatment. Dimensions of the filter tank are analyzed using Huisman
formula. Performance of CSF Septictank is measured by comparing water quality
between water in the initial storage tank and the final storage tank. Water
quality test result shows significance effect in bacterial removal. The other
parameters also show increasing of water quality. By using CSF Septictank,
bacterial contents could be removed 99,15%, BOD5 contents decreases 27,24%, COD
contents decreases 29,01% meanwhile DO contents increases 27,78%
