The CAFE system runs on a small solar powered pump, is gravity-fed and backwashes automatically. It uses next to no energy and doesn’t require any chemicals to function. It is designed to be extremely robust and because it doesn’t have any electrical control panels or complicated moving parts the CAFE is very unlikely to break down, can withstand extreme environments, and can be managed by someone that has limited technical know-how.
The CAFE will remove parasites, arsenic and bacteria – and can take grossly contaminated water and filter it to water that is safe to drink and doesn’t taste funny!
CAFE uses Activated Filter Media (AFM) as its filter media instead of sand. AFM is produced by Dryden Aqua and is made from recycled glass. Using AFM means that the CAFE system is optimised for best performance: AFM is a highly engineered product that – unlike sand – will never allow dirty, unfiltered water to pass through it. You can find out more about AFM from Dryden Aqua.
Our CAFE filter can also be used for aquifer replenishment (i.e. the clean water after filtration can be returned to the groundwater or surface water supply) so, by cleaning up water for drinking we are also having a positive effect cleaning up the whole of the earth’s water systems.
