Ceramic candle water filters

Doulton make these. They have one called sterosyl which has silver impregnated in the ceramic filter, though IMO the standard candle filters will do just fine. 99% pathogen removal.
The beauty of these filters is that they can be cleaned to remove algal and sediment deposits.
I would run the water through a sediment filter prior to running it through the ceramic filter. They do commercial versions also with banks of candles. http://www.doultonwater-filters.co.uk/WWSDoulton/index.asp
Also on Ebay
I'm guessing if you could offer them some publicity you would get the candles and equipment for free.
I have been using these with my rainwater harvesting system for around 5 years, the water tastes much better than local domestic water.
You will need a pumped supply through the filters, although they do also have gravity feed filters so best ask them for advice and how they can work with you. Andrew
