Abstract

Application of microbiological technology to treat saline wastewater is a
new approach to technology to handle problems in life. The study evaluated a
number of factors affecting the growth of Halobacteria-tolerant bacteria to treat
COD in saline wastewater of fish sauce processing plants and fish sauce products.
The results of the study showed that the studied Halobacteria showed very
positive treatment results for COD, under different conditions. Experiments to
optimize bacterial culture conditions show that at 30°C, pH 7.0 and 6% salinity
are the optimal culture conditions for Halanaerobium lacruisei for treating COD.
COD treatment experiments in saline wastewater showed that the ability of this
microorganism to be processed is up to nearly 85%, ensuring that the effluent
meets the environmental requirements.
