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 .
