Biotechnology involves the provision of services to society by microbial communities. By using microorganisms detoxify contaminated water, one such service offers environmentally friendly solutions treatment wastewater. Isolates fungi Aspergillus niger, Candida albicans and microalgal isolates Tetradesmus nygaardi Scenedesmus quadricauda were efficiently utilized for The wastewater sample was t...

The objective of this study was to characterize the wastewater from BIAMBA Marie MUTOMBO hospital in terms physico-chemical and bacteriological parameters, set up a pilot UASB reactor treat water. Two methods were used conduct investigations: observation experimentation. Observations focused on management at its surroundings, point discharge into receiving environment. analysis revealed that so...

Abstract The Niger River, threatened by human activities, is the main drinking water source for population of Bamako city. This study assesses trend River pollution in using Water Quality Index (WQI). Fourteen parameters, namely Turbidity, Potential Hydrogen (pH), Electrical Conductivity, Dissolved Oxygen, Total Solids, Biochemical Oxygen Demand (BOD5), Chemical (COD), Nitrate, Nitrite, Ammoniu...

This study utilized MIKE 11 to quantify the spatio-temporal dynamics of water quality parameters (Biochemical Oxygen Demand (BOD5), Dissolved (DO) and temperature) in Long Xuyen Quadrangle area Vietnamese Mekong Delta. Calibrated for year 2019 validated 2020, developed model showed a significant agreement between observed simulated values parameters. Locations near cage culture areas exhibited ...

This study was undertaken to create an understanding of greywater characteristics and to demonstrate a low cost reuse option involving application of small tower gardens for Greywater treatment and reuse in a peri-urban settlement, Kawaala in Kampala city, Uganda. To realise this, field surveys, greywater and soil sampling and analysis and, tower garden installation at selected households were ...

Rapid increase in population and industrialization leads to huge generation of solid waste throughout the country with landfilling as the most common practice for management of these solid waste. It is estimated that out of 3267 MLD of sewage is generated in Delhi. Concentrations of COD, BOD5, heavy metals, NH4AN, low BOD5/COD ratio and the lack of nutrients in the methanogenic phase have restr...

This study examined the relationship between water quality indicators (five-day biochemical oxygen demand (BOD5) and ammonia nitrogen (NH3-N)) by modeling them at sewage treatment plants (STPs) receiving waters. Discharge loads from 2016 to 2018 were input into QUAL-MEV model, which is used for total maximum daily (TMDLs) in Korea, results showed that simulated BOD5 values decreased according r...

In the context of removal biochemical oxygen demand (BOD5) from food and beverages production wastewaters, this paper reports capabilities SBA-15 modified with (3-aminopropyl)-triethoxysilane (S-APTES) N-[3-(trimethoxysilyl)propyl]aniline (S-Aniline) in glucose, fructose sucrose at very high concentrations (350,000 mg/L for 350,000 170,000 sucrose), i.e. sugars most widely used as sweeteners be...

The vermifilter (VF) is regarded as a sustainable solution for treating rural sewage. However, few studies have investigated the performance of full-scale vermifilter. objective this study to evaluate in reducing organic matter, nutrients, and antibiotic-resistant bacteria contained Influent effluents were obtained from sewage treatment plant using VF UV disinfection system. results show signif...
