Review and report about different literature around Advanced Oxidation Procedure (AOP's) for wastewater treatment. You need to include: A thorough description of the different AOP techniques available for wastewater treatment, including details of the chemical reactions taking place in each AOP. Include individual AOP's like ozone, UV, and the Fenton reaction, but also combinations of these. Summarise the application of AOP's in wastewater treatment, including STP's, and industrial applications like tanneries, explaining how the characteristics of a particular AOP is suitable to a particular waste type. Choose a sector in which AOP's are used (e.g., STP's, tannery, pharmaceutical, etc) and detail some of the key parameters that influence the effectiveness of AOP's in that treatments settings.
Draw a complete process flow diagram for a conventional filtration drinking water treatment plant, labeling each component and indicating its purpose (what it is designed to remove or how it affects removal in subsequent processes). Disinfection by-products: why are they a problem, how are they formed, and how does a conventional filtration plant minimize their formation? The purpose of coagulation and flocculation is to prepare colloidal particles for removal from water or wastewater by a downstream process of settling and/or filtration. The coagulants that are commonly used have two different functions that you should explain. Explain how (the dreaded chemistry) the addition of alum decreases alkalinity and tends to lower the pH of the treated water. (you may want to have a separate slide or graphic to help you explain this). Make sure to discuss how the mixing systems differ between the coagulation (rapid mix) and flocculation (slow mix) steps in the process. Talk about the…

3. A hard drive manufacturer uses Nickel to plate its disks and then polishes them, resulting in a concentration of 50 mg/l in their 50,000 gallons per day wastewater stream. Their industrial permit standard for Ni discharge into the sewer system and treatment plant is limited to 0.2 Ibs./day. What percentage of the mass of Nickel must the onsite treatment system remove to be in compliance with the discharge standard? Use the following formula to determine the daily Nickel loading of the manufacturing system: Loading (Ibs/day) = Conversion Factor (8. Flow(MGD)
Your organization has been hired to provide a water treatment process or device toremove toxic Chromium 6 [Cr(VI)] from water emanating from an underground source.Your organization has developed a treatment process that removes most of the Cr(VI)from the water to a residual concentration of 0.05 mg/L which is an acceptable level inline with the World Health Organisation. The underground water flows at 40 m3/h andhas Cr(VI) concentration of 100mg/L. The effluent flow rate is 97% of the influent flowrate, and the remainder of the water is discharged as wastewater. Calculate theconcentration of Cr(VI) in wastewater.
