Background Lipids are one of the major pollutants in domestic and industrial effluents. The use of lipases in the treatment of these effluents as well as in the bioremediation of contaminated environments represents an environmentally safe alternative to chemical methods [1]. Lipases (EC 3.1.1.3) are carboxylesterases that catalyze synthesis and hydrolysis of long-chain acylglycerols (>10 carbo...

The rapid growth in population and industrialization cause generation of large quantities of effluents. The bulk effluents generated from industrial activities are discharged either treated or untreated over the soil leading to changes in soil properties causing improvement or degradation of engineering behaviour of soil. If there is an improvement in engineering behaviour of soil, there is a v...

In many people’s minds air pollution is associated with the contamination of urban air from automobile exhausts and industrial effluents. However, in developing countries, the problem of indoor air pollution far outweighs the ambient air pollution. There are four principal sources of pollutants of indoor air : (i) combustion, (ii) building material, (iii) the ground under the building, and (iv)...

Naturally occurring and synthetic estrogens and other molecules from industrial sources strongly contribute to the endocrine disruption of urban wastewater. Because of the presence of these molecules in low but effective concentrations in wastewaters, these endocrine disruptors (EDs) are only partially removed after most wastewater treatments, reflecting the presence of these molecules in river...

Visakhapatnam harbor is one of the Indian leading port for which substantial industrial expansion is proposed over the next decade. However, there has been little attempt to date to assess the extent of contamination in sediment and to characterize the potential impacts of contaminants on marine sediment. In this research work author was observed different sediment qualities in different season...

The microbiological quality of effluents from different macrofiltration systems (pressure sand filter and disc filter) used as pre-treatment and membrane technologies (microfiltration and ultrafiltration) was evaluated in order to determine their possible application as alternatives to disinfection of urban wastewater prior to reutilization. Microbiological quality was determined by reference t...

An overview of the important aspects of managing and controlling industrial effluent discharges to public sewers namely sampling, characterization, quantification and legislative controls has been presented. The findings have been validated by means of a case study covering three industrial sectors namely, tanning, textile finishing and food processing industries. Industrial effluents discharge...

The application of Purolite A-510 anionic resin for an industrial effluent treatment generated by the technological process of streptomycin production is studied taking into account the recycling requirements of treated wastewater and recovery demands of all useful materials (e.g., solvents, antibiotics etc.). All the experiments were performed on a laboratory set-up scale by working into stati...
