Wastewater treatment is a process to treat sewage or wastewater to remove suspended solid contaminants and convert them into an effluent that can be discharged back to the environment with acceptable impact.The plants where the wastewater treatment process takes place are popularly known as Wastewater ...
Primary treatment Next, the wastewater enters primary settling tanks, also called sedimentation tanks, for one to two hours. The flow of the water is slowed, allowing heavier solids to settle to the bottom of the tank and the lighter materials to float. At the end of the process, the float...
A process and apparatus is provided for removing color from a wastewater stream. The process includes directing the wastewater stream through at least one UV reactor and simultaneously injecting a hydrogen peroxide charge into the wastewater stream exactly at the UV irradiation zone of the reactor. ...
Fig. 18.2.Specific energy requirements for various wastewater treatment processes: trickling filters (TF); lagoon system (Lagoon); oxidation ditch (OD); membrane bioreactor (MB); activated sludge process (ASP); extended aeration (EA); rotating biological contactor (RBC); waste stabilization ponds (...
Biologicalwastewater treatmentis one of the frontier areas of research in the present scenario. The sewage after treatment may still contain some harmful entities irrespective of the sophistication and ruggedness of the treatment process. Water which was once regarded as the most abundantnatural resource...

1.4. Conditions for getting involved in wastewater treatment process investigation Water being a relevance everyday resource for livelihood has been incriminated with spread of related diseases as there is multiplicity of alternative source and failure in compliance to standard of treatment before release...
And then, the recent advances in the technologies for the treatment of this wastewater are discussed systematically. At last, the future outlook for the development of these treatment technologies is given especially for evaluating the potential and possibility of their industrial application. Overall, ...
