EFFECTIVENESS OF SUGAR EFFLUENT ON FIXEDFILM REACTOR WITH EFFECT OF VOLATALFATTY ACID
Main Article Content
Abstract
Technological solutions allowing the increase of the technological efficiency of
anaerobic methods of wastewater treatment are still under investigation. The weaknesses
of these solutions can be limited by the use of active fillings. As the capability of retaining
microorganisms will act as biofilm factor influencing the performance of this reactor. The
aim of the present study was to determine the impact of fixed film reactor active filling
on the effectiveness of anaerobic treatment of sugar-industry effluent, the production
efficiency and the qualitative composition of the biogas produced. The effluent was
analyzed with varying Organic Loading Rate (OLR) The OLR increased from
0.031kgCOD/m3/day to 0.288kg COD/m3/day. With an average value of Volatile Fatty
Acid (VFA) of The Volatile Fatty Acid was at the maximum of 54mg/l to 24mg/l was
calculated by distillation method with five sets off COD concentrations. The maximum
COD removal efficiency of 86% along with production of 0.048m3/kgCOD of biogas at 3
days Hydraulic Retention Time (HRT) was observed.
