Abstract:

The current study was performed to optimize three different industrial textile effluent biodegradation potentials of a brown rot fungus, Piptoporus betulinus IEBL-3, to reduce environmental pollution. The Response Surface Methodology under the Box Bhenken Design was used for the optimization steps. Three ligninolytic enzymes named lignin peroxidase, manganese peroxidase and laccase were also studied during the biodegradation process. The biodegradation rate of the 3 industrial effluents varied between 67 and 76% at the initially optimized conditions. There was a 10%, 7% and 9% increase in the

Abstract:

Most water treatment facilities collect industrial wastewater in separated effluent pits. This discharge strategy has been proposed by several previous research as a solution to the problems of untreated wastewater being withdrawn further into open sea or rivers, which aims to prevent the pollution of water supplies. However, this solution might also have far-reaching ecological and environmental negative consequences. In this research we have assessed the effluent’s Physico-chemical characterization over the duration of one year, utilizing a specific statistical methodology for a water treatm

ABSTRACT An Allium cepa root cells assay was used to assess cytotoxic and genotoxic impacts on Pharmaceutical industrial effluent in Kano Metropolis. An industrial effluent's physicochemical characteristics and heavy metal composition were assessed, and the readings were found to be higher than the required levels, demonstrating that it had not been treated before disposal. A set of 45 onion bulbs were grown for 96 hours in pharmaceutical effluent that included 2.5, 5.0, 7.5, and 10.0% (v/v), with distilled water serving as the control.

Abstract:

Effluents and soil samples where sediments from the treated effluents are dumped were analyzed for physicochemical properties, metallic and non-metallic ions. These parameters were compared with established international standard (FEPA). Effluents were classified as process waste water (PWW), clarified water (CW), and final discharge (FD). The petrochemical effluents contained very high concentration of TDS (284.00±014 mg/L) and significant concentrations of TSS (78.89±0.01 mg/L), COD (30.10±0.02 mg/L), DO (13.20±0.01 mg/L), BOD (6.12±0.00 mg/L), PO43-(4.34±0.00 mg/L), SO42-(3.59±0.00 mg/L), C

Abstract:

The treatment of effluents requires new methodologies for the treatment of the tailings. One option is the use of natural coagulants. Chitosan has amino groups in the polymeric chains that allow it to act as a cationic polyelectrolyte and present a high density of charges, which are easily adsorbed on negatively charged surfaces, which is the case for most colloidal impurities present in water. Thus, this work used chitosan in the coagulation/flocculation process to remove color, turbidity and suspension of solids, as a strategy in the treatment of effluents. For that, samples of effluents fro
