1. Rainwater is directed from the roof, through 'pre-treatment devices' to help prevent leaves, debris and other pollutants entering the tank. Check with the local Council as to what devices are required, however these should include gutter mesh, rain heads and First Flush diverters
2. Whenever demand for rainwater is detected, and under pressure from the pump, the rainwater is forced through the pleated membrane media of the Rain Filter cartridge.
3. The membrane media in the filter cartridge stops particles passing through - down to either 15 micron (for the Triple Action System) or 80 micron (for the Sediment System). Cartridges need to be replaced when the membrane eventually becomes fully loaded with sediment and flow rate through the filter decreases.
4. The Triple Action System also filters out colour and odour that may taint the water supply, because the membrane used is impregnated with carbon. Carbon is used to reduce/remove colour and odour contaminants.
