The Holy Grail of water technology is a full recycle of all wastewater as potable water (or water of a similar quality) after treatment by enhanced separation. Traditional wastewater treatment systems, mainly based on activated sludge treatment, have a high water loss through the sludge produced, generate a large volume of secondary waste and have insufficient quality of the product water. Newe...

Biosolids are a byproduct of wastewater treatment and contain organic and inorganic materials removed from the wastewater. These residuals are concentrated by various methods to semi-solid form. Likewise, sludge is generated during water treatment and contains solid materials removed from water as well as chemicals added during the treatment process. The final residual water content depends on ...

Wastewater reclamation is an upcoming approach that will significantly affect wastewater treatment systems. Despite the fact that technology for treating wastewater to an effluent water quality that meets various quality standards for reuse is already available and applied, the reuse of water is not just a simple and straightforward road. Significant additional energy and civil infrastructure i...

Wastewater is the spent or used water containing dissolved or suspended solids such as pollutants and microbes, including nutrients. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bod...

one of the major environmental problems in the world, especially in iran is deficiency of water resources. this with respect to the entrance of wastewater (especially industrial wastewaters due to their toxic effects) into the water bodies emphasizes the importance of wastewater treatment. heavy metals such as cadmium, lead and vanadium are part of oil and hence are of the major pollutants prod...

Currently, there is a real need for rapid progress and development in almost all industries areas of human activity [...]

Industries produce millions of cubic meters of effluent every year and the wastewater produced may be released into the surrounding water bodies, treated on-site or at municipal treatment plants. The determination of organic matter in the wastewater generated is very important to avoid any negative effect on the aquatic ecosystem. The scope of the present work is to assess the physicochemical c...

background wastewaters with high salt content disturb the metabolic function of microorganisms causing plasmolysis or activity loss in microorganisms, so the efficiency of biological treatment of saline wastewater by conventional microorganisms will decrease. objectives this study aimed to find the outbreak of disorder in the biological wastewater treatment process and how much salt leads to lo...

Water is a vital element for life and the environment [...]
