2. What is wastewater management?  Wastewater management is the process by which all waste water (waste from showers, toilets, sinks, both residential and most commercial) is treated and returned back to a receiving stream for reuse.

4. Electrocoagulation: New method in wastewater treatment  Electrocoagulation is an advanced and economical water treatment technology. It effectively removes suspended solids to sub-micrometre levels  Electrocoagulation is the process of destabilizing suspended, emulsified, or dissolved contaminants in an aqueous medium by introducing an electrical current into the medium.

5. Requirements of EC  EC reactor is made up of an electrolytic cell with one anode and one cathode. EC system essentially consists of pairs of conductive metal plates in parallel, which act as monopolar electrodes. It also required sacrificial anodes. The requirements to operate EC are a. Direct current power source b. Resistance Box c. Multimeter

9. Advantages  Removes suspended and colloidal solids  Breaks oil emulsions in water  Removes fats, oil, and grease  Removes complex organics  Destroys and removes bacteria, viruses and cysts  Color removal up to 95%  BOD removal > 60%  COD removal > 70%

10. Benefits  Supplied as a skid mounted unit, fully assembled for inlet/outlet and backwash connections  Low operating costs  Low power requirements  Minimal chemical additions  Low maintenance

11. Disadvantages  The ‘sacrificial electrodes’ are dissolved into wastewater streams as a result of oxidation, and need to be regularly replaced.  The use of electricity may be expensive in many places.  High conductivity of the wastewater suspension is required.

12. Applications  Ground Water Cleanup  Surface Water Cleanup  Sewage Treatment

13. Reclamation and Reuse of treated water  Irrigation  Industrial use  Recreational uses  Groundwater recharge  Potable reuse
