Pool water filters
Over the past many years, brand-new share filtration have already been created to resolve the disadvantages presented because of the sand filtration. One of the developed solutions could be the one that use perlite: this technique guarantees a great purification degree (1/2 micron) while the utilization of at least amount of power and water. This technique makes use of diatom in place of perlite, also it calls for minimal room into the technical room.
The Defender filter recommended by Myrtha Pools uses perlite, a volcanic stone with a vitreous framework (like the obsidian rock). This stone is ground and subjected to heat-treatment to have a thin dust that conform at supports creating a stratum of filter material.
The perlite can filter particles because fine as a micrometer.
The diatomite is another news used in the pre-coat filters such as the Defender. The diatomite is defined additionally as diatomaceous planet, a sedimentary siliceous stone with organic origin, mainly consists of fossilized diatom shells (some sort of algae).
The diatomite is described as white colour and elevated porosity. Within types of filters the diatomite can be used in form of slim powder, it adhere during the supports and constitute the filter product.
Advanced of purification (even yet in presence of protozoans)
Presence on the market of filters that manage regeneration and pre-coat independently, simplifying the filter management
