Fifty actinomycete strains isolated from lignocellulosic substrates were examined for the ability to remove the color from a paper mill effluent obtained after semichemical alkaline pulping of wheat straw. Streptomyces sp. strains UAH 15, UAH 23, UAH 30, and UAH 51 were selected for their ability to decolorize the effluent in a liquid medium containing 1% (wt/vol) glycerol, 0.2% (wt/vol) ammoni...

background: conventional wastewater treatment is a combination of physical and biological processes designed to remove organic matter from solution. waste sludge drawn from these processes is thickened and processed for ultimate disposal wastewater contains various kinds of infectious agents, such as bacteria, viruses, fungi and parasites. correct treatment in wastewater treatment plants is imp...

Food processing units is a diversified activity consists of processing of perishable items such as fruit and vegetables, meat and poultry etc. into a various products without the loss of nutritional properties. Liquid waste is generated more in the Food processing units by means of washing of raw materials, pulping, crushing and canning operations. Hence, it is necessary to treat the effluent f...

To develop a better understanding of the issues and best practices related to the use of treated effluent to help maintain river flows and habitat, the Conservancy commissioned a study to summarize the state of the science. The use of treated wastewater effluent is becoming a more prominent factor in Arizona’s overall water management strategy. Treated effluent contains a wide array of chemical...

Hospital wastewater contains pathogenic agents and hazardous compounds; so, it will cause many risks on environmental and human health of different communities. The aim of this research was to investigate the efficiency of hospital wastewater treatment plant in north of Iran. This cross-sectional descriptive research was done on four hospital wastewater treatment plant in north of Iran during 2...

The role of sawdust in the removal of pollutants from textile wastewater has been investigated. The textile wastewater was treated by using sawdust as adsorbent and then filtered. The various physicochemical characteristics of sawdust treated and untreated textile effluent were analyzed. The maximum percent removal of 37% was observed for total suspended solids while minimum removal of 9% for c...

We describe a modification of the most probable number (MPN) method for rapid enumeration of antimicrobial-resistant Escherichia coli bacteria in aqueous environmental samples. E. coli (total and antimicrobial-resistant) bacteria were enumerated in effluent samples from a hospital (n = 17) and municipal sewers upstream (n = 5) and downstream (n = 5) from the hospital, effluent samples from thro...

This paper presents the genotoxic effect of effluent from a pharmaceutical plant in Ota, Ogun state, Nigeria using the rat bone-marrow metaphase chromosome assay. The effluent was examined for some standard physical and chemical properties. Rats were intraperitoneally exposed to 1%, 5%, 10%, 25% and 50% (v/v, effluent/distilled water) concentrations of the effluent for 48 hr. Distilled water an...

Pharmaceutical and personal care products (PPCPs) industries suffer inadequate effluent treatment due to the presence of recalcitrant substances, insufficient carbon source and nutrients. Biodegradation is the ability of microorganisms to metabolize pollutants in soil, sediment and water environment. There is great awareness in the positive impact that microorganisms play in protecting environm...
