Biomethanated Distillery Waste Utilization by Wetland Plant: A New Approach
نویسنده
چکیده
The conventional treatment of distillery effluent including to secondary biologically treatment leaves excessive residue for disposal in surface water and onto the land. Optimal sub-surface loading of Phragmites karka tolerate distillery waste and achieve sustainable zero discharge. Pilot investigations established that subsurface loading into soil matrix (three part river sand, one part pebbles and one part garden soil) of these plants could treat a hydraulic load of 300 m ha day with COD of 10000 mg l with a corresponding total 3 1 1 1 COD load of 137.7±24 ton ha for 45 days during post monsoon periods i.e October to January. Before 1 monsoon i.e. February to June the Biomethanated Spent wash was treated effectively with an optimal hydraulic load of 500 m ha day of COD at 10000 mg l a corresponding total COD load of 229.5±25 ton 3 1 1 1

Ecofriendly utilization of Treated Distillery Effluent (TDE) And Inorganic Fertilizers Management on Microbial Population and Enzymatic Activities
Treated distillery effluent (TDE) generated through biomethanated distillery effluent was applied to arable land for augmenting agricultural production. The TDE contains considerable amount of organic matter and salt besides its high plant nutrients content. With this background, an attempt was made. Field experiments were conducted to study the long term effect of TDE and inorganic fertilizers...

(Received: November 19, 2009; Accepted: March 3, 2010) Abstract: Four microorganisms isolated from samples of mangrove areas were found to be promising and significantly decolorized spent wash. Incidentally, they showed higher phenol degradation and COD reduction as well. The individual colorants imparting the color to spent wash were fractionated. Degradation of melanoidin and caramel was conf...

Effluent ‘Coda’ originating from palmyrah toddy distillery units is the major source of environmental pollution in the Jaffna district of Sri Lanka. Spent wash produced from distilleries is rich in organic material and characteristically less toxic. A research was carried out to find the optimal dilution factor of the effluent before discharge through construction of wet lands which is a new, e...

Hydrodynamic cavitation (HC) was evaluated as a pretreatment option for the complex/recalcitrant biomethanated distillery wastewater (B-DWW). The effect of various process parameters such as inlet pressure, dilution and reaction time on reduction of COD/TOC and enhancement of biodegradability index (BI:BOD(5):COD ratio) of the B-DWW was studied with an aim to maximize the biodegradability index...
