Feasibility study of water purification using vertical porous concrete filter
Journal Title: International Journal of Environmental Science and Technology - Year 2007, Vol 4, Issue 4
Abstract
Cheapest and simplest techniques of filtration systems are required for rural water treatment in developing countries. Using a filter made of blocks for the water treatment enables us to make porous concrete filter and use it vertically. It is expected that the required area would decrease by more than 70 % if porous concrete filters were used vertically. The operation and backwash mode would be simpler than using horizontal sand filters as filters made of blocks would be used instead. The feasibility study focused on finding adequate materials, compositions and methods of making a block with enough resistance to water pressure, sufficient porosity for water transformation and using inexpensive and available materials. A pilot study was performed to determine an appropriate thickness of filter. Testing the porous filter in another pilot study using the low overflow rate of river water showed biological growth in that media and an adequate efficiency of about 90-100 % was obtained for decreasing the coliform bacteria. The required backwash water was 2.9 % of total treated water.
