Abstract

Meningkatnya jumlah air limbah domestik yang tidak diimbangi
dengan peningkatan badan air dari aspek kapasitas maupun
kualitasnya, menyebabkan jumlah air limbah yang masuk ke
badan air melebihi daya tampung maupun daya dukungnya.
Untuk mengantisipasi potensi dampak tersebut, maka perlu
alternatif teknologi pengolahan limbah yang efektif dan hemat
biaya, yaitu berupa biosand filter. Penelitian ini bertujuan
menghitung efisiensi penyisihan dan memperoleh variasi
diameter dan ketebalan media yang optimal dalam menyisihkan
parameter pencemar COD, TSS, nitrat, dan fosfat pada limbah
artificial (campuran black dan grey water).
Hasil dari analisis yang dilakukan didapatkan penyisihan rata –
rata dari reaktor biosand filter 1, 2, dan 3 dalam penyisihan
organik (COD) 74,09%; 76,93%; dan 70,81%, TSS 79,99%;
81,32%; dan 79,61%, nitrat 36,44%; 37,27%; dan 34,62%, fosfat
28,40%; 30,37%; dan 28,39%.. Variasi media yang paling
optimal adalah reaktor biosand filter 2 dengan diameter 0,59 mm
dan kedalaman media 10 cm.

=====================================================================================

The amount of domestic wastewater production has now
increased and over the limit of maximum capacity which
environment able to support.
In order to anticipate the negative potency that occurred, biosand
filter had chosen as an effective and economic alternative of
wastewater treatment. The purpose of this research is getting the
optimum variation of sand filter’s diameter and thickness and
calculating it’s removal efficiencies in terms of removing COD,
TSS, nitrate and phosphate within the mix of greywater and
blackwaterwhich is artificially made.
According to the analysis, an average removal of biosand filter 1,
2, and 3 over COD sequentially were 74,09%; 76,93%; and
70,81%. TSS 79,99%; 81,32%; and79,61%. nitrat 36,44%;
37,27%; and34,62%. fosfat 28,40%; 30,37%; and28,39%.
Biosand filter 2 had came out to be the most optimum media with
0,59 mm of diameter and 10 cm thickness variation.
