Selection Criteria of Water Treatment Strategy in Developing Countries
The selection of an appropriate and affordable water treatment method to obtain safe and clean potable water in the context of developing countries is often a challenge. This chapter draws upon the understanding from the previous chapters of the book where myriad technologies have been discussed. Based on this information, different factors affecting the selection of suitable technology for the treatment of drinking water have been considered. These factors include type of contaminants present in the source water, scale of operation or operations and fixed and operating costs of the system, and they have been considered for choosing suitable drinking water treatment techniques. Both water from surface/ground as well as conserved water in the form of harvested rain water and water reuse have been considered as possible sources of water in this comparison and discussion.
