Community drinking water purification plants from surface water sources in case of arsenic and fluoride-affected habitations.
Pond or wells are the oldest method of groundwater withdrawal for water supply. The water from pond or wells has been found to be relatively free from dissolved arsenic,fluoride and iron.
FLOW CHART :
Pond/well---Pump---Aowal Filter----Pump---- Micron Filters----Activated Alumina Filters----UV Tube disinfection----collection====Supply by 20 Ltr JAR
DESCRIPTION OF PARTS OF THE SYSTEM :
The AOWAL-type sand filter is a low-cost technology with very high efficiency in Iron, Fluoride,turbidity and bacterial removal.
Micron filters remove Turbidity efficiently.
The Activated Alumina Filter removes both Arsenic and Fluoride.We can remove this filter if inlet Arsenic and fluoride content is within permissible limits. This will make our system completely chemical free.
UV Tube disinfects the water before supply.
We work with local NGO partners in both rural and urban areas to implement lasting solutions to water and sanitation issues and provide training.We are looking for PARTNERING with local NGOs.The NGOs can earn on a MONTHLY basis.The water filtered can be supplied in 20 liter jars at a rate of Rs.one per Liter.Expenses is 50 p/lit, So a Profit of 50p/liter is obtained.
This model can generate employment and provide clean drinking water to an entire village or an urban settlement. Local MLA or Gaon Panchayat can fund the project.
Case Study:
Source of Water : Pond, Well
to provide 8-10 litres per capita per day (LPCD) of safe drinking water for drinking and cooking purposes in areas affected by fluoride, arsenic, heavy metals and pesticides.
Quantity: 3000 Liter per day (For 300 persons @10 liter per person per day ).
Project Cost.: .Equipment cost will be around Rs. Three Lac.To design a system we need
1. The total quantity of water to be treated
2. A water test is recommended of the following parameters
.
| Source of water | Pond/well | |
| 1 | pH | |
| 2 | Turbidity(NTU) | |
| 3 | TDS | |
| 4 | Total hardness as CaCO3 | |
| 5 | M-Alkalinity as CaCO3 7 | |
| 6 | P-Alkalinity as CaCO3 | |
| 7 | Total iron as Fe | |
| 8 | Total Chloride as Cl | |
| 9 | Residual Chloride as Cl | |
| 10 | Ammonical nitrogen as NH3 | |
| 11 | Nitrate nitrogen as No3 | |
| 12 | Fluoride as F | |
| 13 | Sulphate as SO4 | |
| 14 | Calcium as CaCO3 | |
| 15 | Ammonical nitrogen as NH3 | |
| 16 | Arsenic | |
| 17 | Coli form(Bactoriology tests) |
