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.
