Excellent results for AFM® in comparison with quartz sand and other glass filter media
The Dryden Aqua Team is proud to share with you the excellent outcome of the tests on AFM® in comparison with quartz sand and other glass filter media that were conducted by the “Institut de la Filtration et des Techniques Séparatives” IFTS in France.
Dryden Aqua founder Dr Howard Dryden explains what drove him to look for alternatives to traditional sand in pool filtration
The heart of any swimming-pool water-treatment system is the sand in the sand filter. However, like any heart it does not work well unless it has a good support structure and circulatory system. The performance of the water-treatment system in a pool depends on the quality of the sand – yet there is huge variation in sand quality from different suppliers and quarries. The best sand in the UK is considered to be the Leighton Buzzard deposit.
