Pengaruh Variasi Debit Udara Terhadap Efisiensi Penyisihan Cod Dan Nitrogen Total Dalam Limbah Cair Hotel Pada Sistem Moving Bed Biofilm Reactor (Mbbr) Menggunakan Chorella Sp.

ABSTRACT
Hotel wastewater contains pollutants such as BOD, COD and Total Nitrogen if
discharged directly the environment has a harmful effect on the environment. If
not processed it will cause excessive growth of algae or aquatic plants
(eutrophication). The study was conducted to determine the efficiency of waste
treatment hotel in reducing the parameter of COD and Total Nitrogen using the
method Moving Bed Biofilm Reactor (MBBR) by utilizing Chorella sp. This
research was carried out by growing biofilms on kaldness (K1) media and air
injection by aerators with variations of air injection 3 L/minute ; 6 L/minute ;9
L/minute ; and control (without air injection) with processing time of 5 days.
Based on the results of wastewater treatment research hotel with the MBBR
method with air injection 6 L/minute, it was able to reduce the parameters of
COD and Total Nitrogen to below the quality standard. The highest cell density of
Chorella sp. suspended and attached in a row that is 1,595 dan 1,587 (x107
cell/ml) with the density of the cell is able to reduce the COD parameter from
concentration of 485,6 mg/L to 80 mg/L and efficiency of 83,53 %, and from
concetration 146 mg/L to 4 mg/L with Total Nitrogen efficiency of 97,26 % so that
hotel wastewater doesnot pollute the environment if it is discharged into water
bodies.
