Engr. Nwaogwugwu,
Had you considered alternative treatment techniques to coagulation and sedimentation? Membrane filtration can be an economical substitute for conventional chemical treatment technologies. I would recommend that you take a look at membrane treatment as an alternative. One charity that provides membrane systems in various configurations for community water systems and emergency water supply is the SkyJuice™ Foundation out of Australia. The founder of this charity, Rhett Butler, has long experience in the commercial membrane business and has been fully engaged with this charity for at least a decade. See their web site here: http://www.skyjuice.org.au/. They have provided manual and pressurized systems for communities up to 5,000 persons.
Best wishes,
Randal Samstag

Membranes will eventually need to be chemically cleaned or replaced. Although a well-designed membrane with adequate pretreatment should last 8 to 10 years. In any case, good to see charities looking into sustainable solutions.
