Penurunan Konsentrasi Biological Oxigendemand (BOD) dan Total Suspended Solid (TSS) pada Limbah Septick Tank dengan Menggunakan Reaktor Fluidized Bed Media Styrofoam Saat Start Up
Abstract
Waste water which not yet experienced of treatment can be certain to
contain many undesirable components. If thrown to territorial watersenvironment,
in some between others will be show the problem of oxygen decrease, while
another possible stimulate growth of certain microorganism like alga. The
components consist of materials organic and inorganic, as well as dissolved or not
dissolved. In this research is conducted treatment of domestic waste by using
Fluidized Bed Reactor with Styrofoam media. The objective of this research is to
know degradation of Biological Oxygen Demand ( BOD) concentration and Total
Suspended Solid (TSS) concentration in domestic waste at the time of startup.
In this research is used Fluidized Bed reactor made of plastic which
consist of two partition where in each partition have an media of Styrofoam
diameter 0,5 cm as much as 15% from the height. Before treatment of domestic
waste which grow bacteria is done, that is conducted bacteria starter to give
addition early bacteria from outside until motivate process forming of biofilm at
growth media, that is Styrofoam. This Process is conducted by stream water of
septictank which have been given bacteria of EM4 addition from reservoir into
reactor. Sampling process is done from first day of startup after bacteria starter
until before situation of steady dead. The Method used for Examination of BOD
titrimetri according to SNI M-69-1990-03 and Method Examination Of Water
Quality Physics SK SNI M-03-1990-F for TSS.
The research conducted until 30 days at the time of startup show
degradation of BOD concentration equal to 39.17 % and degradation of TSS
concentration equal to 60,6%. The Percentage mean of change pHequal to 2,32 %
and temperature 1,46%. Value of pH and temperature is still good for the start up
condition.
Degradation of BOD concentration happened caused by decomposition of
organic matter by microorganism while degradation of TSS happened caused by
screening process.
