ABSTRAK

Tujuan dari penelitian ini adalah memperoleh efisiensi penyisihan serta variasi ketebalan dan diameter media pasir yang paling optimal dalam menyisihkan COD zat padat nitrat dan fosfat dari air limbah dengan menggunakan aerasi bak pengendap dan biosand filter. Dimensi bak pengendap yang digunakan yaitu 77cm x 20cm x 20cm panjang x lebar x tinggi. Media yang digunakan pada reaktor biosand filter adalah pasir dengan variasi ketebalan 5cm dan 10cm serta diameter 059mm dan 119mm. Pengaliran air limbah diatur menggunakan valve dengan debit 30ljam atau 83mldetik. Hasil dari analisis yang dilakukan didapatkan penyisihan rata rata dari aerasi terhadap parameter COD 1935 zat padat 429 nitrat 584 fosfat 456. bak pengendap terhadap parameter COD 2707 zat padat 6062 nitrat 867 fosfat 748. Selanjutnya untuk biosand filter 1 2 dan 3 dalam penyisihan COD 5190 5930 dan 3969 zat padat 8194 9089 dan 7922 nitrat 2272 2802 dan 2019 fosfat 2049 2282 dan 1687. Variasi optimal pada penelitian ini adalah reaktor biosand filter 2 dengan ketebalan media 10 cm dan diameter 059mm.


ABSTRACT

The purpose of this research is obtaining removal efficiencies and optimal variation of diameter and thickness of the sand used in biosand filter to remove cod nitrate posphate and total suspended solid contained within the water sample using an aeration and sedimentation as a pre-treatment. The dimension of the sedimentation used in this research is 77cm x 20cm x 20cm length x width x height. Variations are 5cm and 10cm in thickness 119mm and 059mm in diameter. Water flow was set to 30lhr or 83mlsec using plastic valve. According to recent analysis we obtain an average removal of cod nitrate posphate and total suspended solid sequentially in aeration was 1935 429 584 456. In sedimentation was 2707 6062 867 748. In biosand filter 1 2 3 was 5190 5930 3969 for cod. 8194 90897922 for total suspended solid. 2272 28022019 for nitrate. 2049 2282 1687 for posphate with biosand filter 2 became the most optimum variation in overall parameters removal as we saw above.
