Abstract
Air Limbah yang disalurkan melalui saluran drainase dan
efluen tangki septik yang memiliki kualitas air yang buruk. Air
yang telah tercemar karena dapat terdegradasi dan membentuk
biomassa baru berupa sludge penyebab luas penampang sungai
atau selokan berkurang, sehingga diperlukan bangunan yang
tepat dan efektif untuk mengolah air limbah .
Limbah diolah menggunakan anaerobik biofilter dan tangki
septik. Media yang ditinjau didasarkan atas perbedaan porositas
dan luas permukaan dimana kerikil memiliki porositas 50% dan
media plastik memiliki porositas 98%.Hasil perhitungan
didapatkan dimensi dari tangki septik mengikuti pola persamaan
((1.2+ 0.1n)x(0.6+0.05n)x1)m. Bak biofilter media kerikil
mengikuti pola (1.25 x(0.42+0.52log(n)x1.25)m dan media plastik
mengikuti pola (1.25x(0.5+0.631log(n)x1.25)m, dimana variabel n
merupakan jumlah tambahan orang.. Tangki septik mampu
mereduksi COD dan BOD sebesar 38.5% dan 40.81%, Biofilter
Anaerobik media kerikil dapat mereduksi COD dan BOD sebesar
68.8%dan 75.82% sedangkan biofilter anaerobik media plastik
dapat mereduksi COD dan BOD sebesar 68.3% dan
76.16%.Biaya yang dibutuhkan untuk pembangunan bangunan
pengolahan untuk tipe rumah 49 media kerikil batuan kerikil dan
plastik adalah Rp 4.693.954 dan Rp4.751.865. Tipe Rumah 79
media kerikil batuan dan plastik adalah Rp 6.187.803 dan
Rp6.242.925. Tipe rumah 129 media kerikil dan plastik adalah Rp
7.660.932 dan Rp7.815.840. =========== Wastewater is channeled by drainage channels and septic
tank effluent where having poor quality. Contamined water will
have negative impact to the environment because can be
degradated, thus forming new biomass and form mud sediment or
sludge that will be able to be cause of flooding due to reduction in
surface area river or channels, so required effective treatment.
Wastewater is treated using anaerobic biofilter and septic
tank. Media where reviewed based on porosity and surface area
where porosity of rock gravel is 50% and surface area is 100
m2/m3 and plastic media have porosity 98% and surface area
150 m2/m3. The Calculation result dimenstion septic tank follow
pattern (1.25 x(0.42+0.52log(n)x1.25)m, gravel rocks biofilter
media follow pattern ((1.25 x(0.42+0.52log(n)x1.25)m, and media
plastic follow pattern (1.25x(0.5+0.631log(n)x1.25)m, where
variable n is additional people that filled minimum 5 people. The
septic tank can reduce of COD and BOD are 38.5% and 40.81%.
Biofilter media Anaerobic gravel rocks can reduce of COD and
BOD are 68.8% and 75.82%. Anaerobic biofilter plastic media can
reduce COD and BOD 68.3%, and 76.16%.
The costs is needed to build a treatment plant with 49 type
using media gravel rock and plastic are Rp4,693,954 and
Rp4,751,865 . 79 Type medium gravel rock and plastic are
Rp6,187,803 and Rp6,242,925. 129 Type use media houses rock
gravel and plastic are Rp7,660,932 and Rp7.81584.
