## Title: Low-Cost Household-scale Greywater Treatment Solutions Applicable to Dhaka City Region

### Subject paper: GREY WATER RECLAMATION FOR URBAN NON-POTABLE REUSE - CHALLENGES AND SOLUTIONS: A REVIEW
Material              : Water Sampling
Data Collection : From student  accommodation hall in Loughbrough University and 
                collected grey water was compared with other sample where one sample was colleced from office buliding
Data Analyisis :    Tabular Analysis  
                Test Done in Lab : BOD , COD, TSS, TDS, TOC, PH
Components :  Inorganic carbon 
             Phosphate 
             Nitrate 
             Ammonia 
             Sodium 
            Chloride 
             Sulphate 
Health Risk: Micro organisms cause skin and eye infection, inhaling aerosol cause breathing         problems .
Environment: Nitrogen, phosphorus, potassium useful for plant growth 
However detergent ( Sodium, boron, chlorine) harmful for plants 
Effects: discolouration, burning of leaves, leaf cupping , prevents calcium ions reaching the plants, soil ability to absorb water
Process of Detergent removal: 1) physical filtration 
2) Nano filtration 
3) Reverse osmosis
4) Micro and ultra filtration 
For chemical process:
5) Coagulation & Floculation
6) Adsorption 
3)Disinfectant killing 
7) ion exchange process 
8) Micro Biological growth
