The aim of the study was to investigate distribution, enrichment and accumulation of heavy metals in soil and Trigonella foenum-graecum (var. Pusa Early Bunching) after fertigation with paper mill effluent. Doses of paper mill effluent viz. 5%, 10%, 25%, 50%, 75% and 100% were used for fertigation of T. foenum-graecum along with bore well water (control). The results revealed that paper mill ef...

An experimental study was carried to find out the degradability of black liquor of pulp and paper mill wastewater for biomethanogenesis in continuous stirred tank reactor (CSTR) and followed by activated sludge process (ASP). Continuous stirred tank reactor was used in present study for anaerobic digestion of black liquor, while completely mixed activated sludge system was used for aerobic dige...

Sugar Factory effluent is one of the most important moderate – high pollution concentration wastewater, which is generated mainly from the mill house washing activities of the sugar factory. The effluent is rich in organic matter resultant from the sugarcane juice, sugar syrup and sugar present in the washwater. The COD of this effluent is variable from 5000 – 10000 mg/L. The aim of the present...

The increasing costs associated with water supply and the disposal of wastewater has stimulated industries to seek more efficient water management systems. Mathematical modelling and simulation can be a very valuable tool for the study of the multiple alternatives available whilst assessing optimum solutions for water management in industry. This study introduces a new steady state model librar...

Sugar-mill wastewaters have potential to support microalgal biomass production for use as a biofuel feedstock (lipid source). Growth kinetics, light dynamics, and lipid production in multispecies-microalgae cultures collected from a sugar-mill pond are reported in this paper. Lipid content of the microalgae collected from the pond water was 14.5 % (w/w). Culturing the same microalgae in a photo...

As the world's population increases, so does amount of wastewater generated during agricultural activities. Inadequate management can be cause sea and river pollution. However, a potential source biologically active components that obtained via physicochemical, biological, thermochemical or combined treatments. Olive mill is produced in huge quantities around world production olive oil. This wa...
