Goswami, Lalit published the artcileA novel integrated biodegradation-microfiltration system for sustainable wastewater treatment and energy recovery, Quality Control of 929-77-1, the main research area is integrated biodegradation microfiltration system wastewater treatment energy recovery; Biodiesel production; Bioremediation; Ceramic membrane; Industrial wastewater treatment; Rhodococcus opacus.
This work assessed the treatment of wastewater generated from three different industries viz., paper and pulp, biomass gasification and dairy by biodegradation followed by membrane filtration. Batch biodegradation was first carried out using wastewater as the potential substrate for oleaginous Rhodococcus opacus with lipid accumulation intracellular; subsequently, a microfiltration system was applied to recover the bacterial biomass grown as well as for residual COD (COD) removal from the effluent. The combined process showed excellent results in terms of COD removal from the industrial wastewaters, with the values 56.8%, 46.1% and 68.9% for dairy, paper and pulp and biomass gasification wastewaters, resp., by biodegradation These values were further improved to 92.7%, 87.6% and 88.2%, resp., following the microfiltration step performed by employing a low-cost ceramic membrane. In addition, lipids accumulated by the bacterium were extracted and characterized for biodiesel production potential. Lipid characterization using 1H NMR confirmed the presence of saturated fatty acids. Gas chromatog. anal. of the transesterified lipids revealed the presence of Me palmitate and Me stearate. In addition, the estimated properties of the transesterified product affirmed its potential for biofuel application.
