Low-cost off-the shelf water filtration product?
Can anyone suggest a low-cost off-the shelf water filtration product? The communities which the water supply is to be installed are very small so it may make sense to install purification/filtration within households rather than for the community as a whole. The supply is relatively clean but may contain some particulates and bacteria.
Past experience here has been with larger-scale concrete installations which use sand-filtration. The budget for these sites is particularly low and time-scale is also short. Any suggestions for good easy-to-install devices would be appreciated!
There is a UK product called the Aquafilter used for fairly small scale projects (about 60 litre/hour) originally developed for disaster releif but also used as permanent supplies. The web site www.grifaid.org has details, they dont quote a cost per unit but probably a few hundred UK pounds per unit, a working life of 6 years is quoted. The product is often distributed by charities as part of an aid package for disaster releif.
