Description 110-116
A lab-scale Hybrid Upflow Anaerobic Sludge Blanket (HUASB) reactor with a working volume of 6.5 litres has been
taken for the performance analysis, in the treatability study of pulp and paper mill wastewater. In order to analyze
the performance of the reactor, operational parameter like hydraulic retention time (HRT) was varied from 10, 20, 30
and 40 h. In addition to that, performance parameters like chemical oxygen demand (COD), pH, volatile fatty acids (VFA), alkalinity, gas production and VFA/alkalinity ratio are analyzed to check the reactor efficacy. The maximum COD removal efficiency of 81.3% is obtained at 40 h HRT, with gas production (methane content of 58%). Also, the obtained results
are fitted to the kinetic models like the standard first order, first order and second order to evaluate the performance
of the HUASB reactor.
