Grey Water recycling Treatment

This includes the prototype of grey water, like is there possibility of portable greywater recycling system. It includes a lot of information about grey water and a system where it is practice. Its uses, limitation of current system that its not so portable. Future scope is also mentioned. Components used is the system. Enjoy.

2. I ntroduction Greywater  or  sullage  is wastewater  generated from basins , showers and baths . It differs from the discharge of toilets which is designated  sewage or  Blackwater   to indicate it contains human waste. Recycled on-site for use in  toilet flushing , landscape irrigation and constructed wetlands.  

3. Introduction For irrigation purpose, According to standards of Central Pollution Control Board, permissible value of BOD ( Biochemical oxygen demand) is 30 mg/l COD   (Chemical oxygen demand) is 250 mg/l in India Currently, we are dealing we COD of upto 1000mg/l and reducing it to approx. 200 mg/l Fig. Data from different areas show amount of COD in different activities

4. Goals & Objectives To reduce COD (Chemical o xygen d emand) of the grey water, so that is it reuseable for flushing purpose Portability of system is increased, so that its assembly and disassembly is simple, resulting in easy trouble shooting. Easy maintenance

5. Literature Survey Sr. No. Paper Name Year Author Description 1 Treatment and potential reuse of greywater from schools : a pilot study 2017 Abdalrahman D, Alsulaili , Mohamad, Hamoda . Rawa Al- Jarallah Easy maintainence and low cost system for on-site treatment and reuse of water collected from water sinks and fountains, as major sources of greywater(GW) at schools. 2 Greywater reuse in residential schoold in madhay pradesh – A case study of cost – benefit analysis 2009 Sam Godfrey, Pawan Labhasetwar , Satish Wate Cost- benefit analysis was undertaken for greywater reuse by considering internal and external costs and benefits. 3 Greywater reuse: A stategy for water demand management in harare . 2007 Emaculate Madungwe , Saniso Grey water reuse in African countries to sustain the demand of agriculture purpose.

6. Existing System & Limitations The system used for grey water treatment which results in foul smell, which is further is large in size yet uneasy in installation and not portable. Limitations : Not portable Huge size Not easy to install Generates f oul smell High maintainence

7. Proposed System More Natural Solution unquestionably The current system solves the issue of PORTABILITY, which gives user only the job of assembling the system. The system has easy maintenance. Easy Trouble-Shooting Less Foul smell

8. How will the system function? Collecting the grey water from the source Grey water then flows through m echanical filter for removal of any particulate matter that would clog the system Then through pipe into the crates where water bed is formed (x 6) resulting in reduction in COD Two layers of crates (3x + 3x) are attached through siphon so that water flows from layer to another W ater is collected into a tank from crates which is reduced in COD and ready to be reused The collected water is pumped into the tank on the roof where constant bubbling is done inside the tank and from there it is distributed for flushing , irrigation or gardening purpose.

9. Components 1000l 48W 175l 2 inch 0.5HP

10. System architecture

11. The system is transportable, movable, mobile COD is minimized heavily Rigid Structure Reduces Waste Advantages of Proposed System Less Maintainence required System is more naturally driven Reduces Cost giving more storage of water Flexibility in upgrade

12. Future Scope More portable designs to satisfy storage need Increase flexibility of the system Improve portability Trouble shoot existing problems

13. Conclusion Our proposal of grey water system considering the current problems has been succesful to an extent. There is always room for improvement with Portability issues Space constraint Level difference Flexibility in Cost
