BIOREMEDIASI LIMBAH CAIR SENTRA INDUSTRI TEMPE SANAN SERTA PERENCANAAN UNIT PENGOLAHANNYA (KAJIAN PENGATURAN KECEPATAN AERASI DAN WAKTU INKUBASI)
ABSTRACT: This objective of
the research was to design and implement Waste Water Treatment Unit for Sanan’s
tempeh using bioremediation technique to produce free pollutant waste complying
with standard environmental regulation for tempeh liquid waste before it is
dumped into the waterways. This experiment is designed using Randomized Group
Design. It consists of two factors which are, firstly, variation of aeration
speed ( 1 vvm, 2 vvm, 3 vvm), secondly, variation of incubation time ( 0 days ,
3 days, 7 days). It was shown that the best treatment, the combination of 3 vvm
of aeration speed and 7 days of incubation time
capable to reduce up to 83.9 % of BOD; 73,1% of COD; 93.1% of TSS and
45.8 % of detergent. The value of BOD and COD has satisfactorily complied with
standard environmental regulation for tempeh liquid waste, which is the value
of TSS and detergent just nearly complying. The Treatment Unit designed for
treating tempeh liquid waste of about 45 m3 /day in average is consists of
pre-sediment tank with the capacity of 100 m3, 7 aeration tank with air
compressor, final-sediment tank, controlled tank which has a capacity the same
as pre-sediment tank and calcium-bicarbonate solution tank. The area for
building Waste Water Treatment Unit is 1440 m2.
