The Industrial and Municipal Waste Management component of the Lake Victoria Environmental Management project carried out an assessment to determine pollutant loads from point sources, which included industrial and municipal effluents and urban run-off from the Uganda catchment of Lake Victoria. Identification of pollution hotspots that pose threats to Lake Victoria was done, and the fishing vi...
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...
background: wastewater produced by a dairy in sanandaj is a major source of environmental pollution threatening the city. the dairy uses activated sludge treatment to remove organic pollution from the wastewater. the present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (cod), biochemical oxygen demand (bod), and total s...
One motivation for our study concerns an environmental application that regards the identification of pollution sources in surface water: in a river, for example, the introduction of organic matter which could have as origin city sewages, industrial wastes,... usually drops to too low the level of the dissolved oxygen in the water. Since the lack of dissolved oxygen represents a serious threat ...
Water is one of the most important elements involved in the creation and development of healthy life. Haphazard disposal of untreated wastewater from households as well as institutions and industry is causing severe deterioration of water bodies in many urban areas in the developing world. There are several methods to treat the municipal wastewater for intended use. One of the methods of the tr...
Microbial fuel cells represent an innovative technology which allow simultaneous waste treatment, electricity production, and environmental monitoring. This study provides a preliminary investigation of the use of terrestrial Single chamber Microbial Fuel Cells (SMFCs) as biosensors. Three cells were created using Andean soil, each one for monitoring a BOD concentration of synthetic washed rice...
Objective: To evaluate the changes in ovarian volume and the reproductive outcome after unilateral (UOD) and bilateral (BOD) laparoscopic ovarian diathermy in infertile women with Clomiphene Citrate resistant PCOS. Material and Methods: The ovarian volume in both groups was measured by transvaginal ultrasonography preoperatively and up to 10 days after laparoscopic ovarian diathermy and examine...
