Removing turbidity of drinking water used to be taken from open surface ponds in Rural Areas "is there are effective ways"

Published on by

Most of the rural areas in the "Development countries", the rural communities depend on the surface water such as irrigation channels or surface open ponds for their drinking and other domestic uses. Towards the end of the cultivation season water supply in the irrigation channels is occluded, then the water became shallow and turbid, and by the end of rainy season the remaining water in the surface which collected in surface depressions (open ponds) becomes depleted too by vaporization, and then the both of water sources ultimately becomes turbid and contaminated, which constitutes a hazard for rural inhabitants.

This warrants upgrading water quality through purification, decreases of turbidity, and removal of pathogens.

Turbidity

The turbidity of the surface water is resulted when the rain water running across the surface of the ground, through this running courses towards the surface depressions to form the surface open ponds it's picks up many substances such as suspension materials , collided materials ,minerals ,salts ,organic and inorganic materials ,all these added materials causes the turbidity of water ,This turbidity provided a perfect medium and adsorption site for the chemicals , organic and biological reactions resulting the aesthetically and undesirable tastes and odor ,also the turbid water provides a perfect medium for the growth of all type of microorganisms and pathogens which is responsible for causing the people the majority of diseases and infection ,

  1. Packaged Slow Sand Filtration: is a process where untreated water seeps slowly down through a layer of fine sand, then through a layer of gravel, and ultimately collects in a system of under drains. A complex biological layer, called schmutzdecke, forms on the surface of the sand filter, trapping small particles. It also helps decompose organic material in the water.

  2. Hello Charles, So far the Slow Sand filter is used to purify water at the stage of the Householder ,As you mentioned the Food challenge governs the farmers toward using the Agro-chemicals in order to maximize the crop yields for both to satisfaction of Food Demands and to upgrade the Economy of the most of the developing countries .The Technical restriction ,poor institutions and luck of strategical planning in the Developing countries Slowing down the utilization of the new technologies that would maximize the crops production and minimize the hazard of Agro -chemicals .

  3. Hello Hussein, This discussion is very critical because it defines exactly the situation as it is in some of our rural areas where the profession is predominantly agriculture. Of course with increase in population world-wide and the need for food production at large scale to meet the food challenge, different strategies have been employed ranging from mechanization and the use of agro-chemicals. All these are washed into pond and other forms of stagnant water which the rural people unknowingly fetch for their domestic uses; be it drinking or cooking etc. Added to what you earlier mentioned, there is a purification system that is called slow sand filtration which is less expensive and can be adapted in rural areas to purify such water apart from the use of chemicals.
