Treatment Of Slaughterhouse Effluent Using Upflow Anaerobic Packed Bed Reactor
Most of the slaughterhouses in the state of Kerala (India) do not have proper and effective effluent treatment facilities. Collection of blood and separation of manure to reduce the very high organic load of the effluent are also not practiced. As a result, large volumes of extremely complex effluents with high content of fat, grease, and protein are discharged into land or water bodies causing...
متن کاملThe Influence of Pressure on the Liquid Hold-up in a Cocurrent Gas-liquid Trickle-bed Reactor Operating at Low Gas Velocities
The influence of reactor pressure up to 6.0 MPa on the dynamic liquid hold-up in the trickle-flow regime with superficial gas velocities up to 5.2 cm/s has been investigated for water, ethanol and aqueous 40% ethyleneglycol, with nitrogen as the gas phase. Without gas flow, i.e. single-liquid trickle-flow operation, the reactor pressure has no influence on the dynamic liquid hold-up, which can ...
متن کاملOrigins of Pulsing Regime in Cocurrent Packed-Bed Flows
The mechanism of the formation for cocurrent downflow pulse flow was studied experimentally in a packed-bed of inert spheres of 3, 6, and 8 mm using an air-water flow. By measuring the flow distance until pulses are observed, the spatial growth rate of convective disturbances within the pulsing-flow regime were determined. Observations indicate that pulses form from trickling-flow as the result...
متن کاملTreatment of rayon grade pulp drain effluent by upflow anaerobic fixed packed bed reactor (UAFPBR).
The Rayon grade pulp (RGP) drain effluent of pulp and paper mill was studied to find out pollutant loading and its control measures by low cost and efficient treatment method. Upflow anaerobic fixed packed bed reactor (UAFPBR) with brick ballasts as packing material was used for this purpose. This was compared with conventional anaerobic treatment method. The digested slurry was taken as inocul...
متن کاملOptimal synthesis of rotating packed bed reactor
Rotating packed bed (RPB), a novel apparatus involving process intensification (PI), has been successfully used in the chemical industry in recent decades. In this paper, we establish a connection between process integration and process intensification for which we propose a superstructure involving a RPB and a packed bed (PB) in order to determine the optimal integrated design. We describe mod...
