TREATMENT OF TAPIOCA WASTEWATER BY USING BIOLOGICAL HYBRID SYSTEM
Abstract
Tapioca processing industry discharged into environment a significant amount of pollutants. Where, organic compounds, nutrient, and toxin CN- concentration exceeded Vietnamese discharged Standard up to hundreds of times.
The study on biological hybrid system, combining aerobic biofilter and aerotank attained COD, N-NH3 treatment efficiencies in range of 98%, 95%, respectively at the optimal organic loading rate of 1 kg COD/m3.day, according to hydraulic retention time of one day. Biomass of microrganism in this system can reach to the value of 10,000 mg/L.
The effluent reached to Vietnamese Standard 5945-2005, column B
