pollution sources into the water, the necessity of qualitative studies of water resources is one of the most important new challenges for mankind in almost every parts of the world. dissolved oxygen (do) and biochemical oxygen demand (bod) are among parameters of water quality indexes which are considered as water pollution indexes. in the present research, do and bod of dez river basin water (...

the idea of systems analysis and mathematical modeling for formulating and resolving river pollution issues is of relatively recent vintage and has been applied widely in the last 3 decades. the present study illustrates the utility of beck-modified khanna–bhutiani model (bmkb) to determine the pollution load due to the presence of organic matter in river ganga from its course from devprayag to...

Moving bed biofilm reactor (MBBR) is a process in which attached growth is utilized for wastewater treatment. This process does not require sludge recycling or backwash. Activated sludge processes can be promoted to an MBBR by adding media to an aeration tank. Rapid sand filter is a physical method for the removal of total suspended solids (TSS) in advanced wastewater treatment. The purpose of ...

background: yazd waste stabilization pond facilities consist of three stabilization pond systems, module 1, module 2 and module 3 that awsp module 1 has started its operation. the existing facilities have had several problems in their operation. the objectives of this research were to evaluate the performance of stabilization ponds in wastewater treatment of the city of yazd, due to several pro...

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...

The oxidation-absorption technology of tail gas is perfect for natural purification plants to ensure the up-to-standard discharge sulfur dioxide emissions, but it can produce a large amount wastewater. In this paper, facile and full-scale reuse treatment strategy based on sequential combination disc tube reverse osmosis low-temperature low-pressure evaporation desalination was proposed studied....

The quest for an effective alternative means for effluent treatment is a major concern of the modern-day scientist. Fungi have been attracting a growing interest for the biological treatment of industrial wastewater. In this study, Saccharomycescerevisiae and Torulasporadelbrueckii were isolated from spoiled watermelon and inoculated into different concentrations of effluent. The inoculants wer...
