Why is the performance better than other systems?
1. Most RGF Rapid Gravity filters operate at a flow velocity of 6m / hr. The Solari Community Water Filter runs at 2m / hr. Filtration performance is inversely proportional to filtration velocity, so the flow is slowed down.
2. All RGF filters for municipal supplies of drinking water use sand media close to 16 x 30 grade( 0.5 to 1.0mm). The sand is not certified and varies greatly in quality as well as performance. The Solari Community Water Filter uses grade 0 AFM( 0.25 to 0.50), which provides for a much better performance than sand. AFM also adsorbs small submicron particles and is manufactured under controlled conditions to an exact specification. AFM was verified by IFTS to be an order of magnitude better than sand for the removal of suspended solids under 5 microns.
3. All RGF filters suffer from bio-dynamic instability leading to transient channeling of unfiltered water into the product water. In countries with ambient water temperatures under 20 deg C, sand filter performance is usually better than 99.5 %. In countries over 20 deg C, filtration performance is typically over 98 %. It only takes a filter to fail 0.1 % of the time to cause disease among people supplied by the network. Our Solari Community Water Filter may be used, or AFM may be retrofitted to replace the sand used in RGF or pressure filters supplying cities, there is no limit to the scale of the system.
4. AFM media never needs to be changed. This is important because the filter is designed to last for 20 + years, so the filter media must last for the same duration.
5. Better than UF ultra filtration? Yes, because AFM will not only filter down to 0.1 micron but will remove many particles below 0.01 microns as well as chemicals from solution, which is impossible for UF. Performance is better than UF, much lower cost with a system that is self-running and really easy to maintain.

Other applications
The Solari Community Water Filter with AFM is a perfect solution for rural community drinking water as well as any application that requires water treatment to a high standard. AFM manufacturers Dryden Aqua are marine biologists, and have been filtering seawater for marine aquaria and high end aquaculture systems for 30 years. AFM is also used as a pre-treatment media for desalination systems in the Gulf and around the world. An important application is the tertiary treatment of municipal waste water for direct second use as class 1 irrigation water, or as a pre-treatment prior to RO membranes. The Solari Community Water Filter can cope with grossly polluted water, up to a concentration of 200mg / l suspended solids, or even with oil in water up to 100mg / l from Palm oil processing, fracking and oil industry waste water.
