FILTERING LOADS

Did you know that 80% of water treatment is done through filtration?

​

By retaining the largest polluting agents and insoluble particles, filtration facilitates disinfection because it allows faster and more effective action of treatment products.

​

The best-selling filters are the sand or glass filter and the cartridge filter. But which filter media should you choose?

​

Filter Sand

Advantages :

​

• Filter media very affordable to purchase

• Sufficient filtration fineness between 20 and 40 µm

• Good lifespan

Disadvantages:

• Requires frequent backwashing to prevent clogging of the filter, which causes additional water consumption

• Creation of a biofilm which decreases filtration performance

• The sand requires 2 chemical cleanings per year with a sand filter cleaner to avoid scaling up

 

​

Filter Glass

Advantages :

​

• Eco-friendly material

• Offers a fineness of filtration of 15 microns, which is excellent for an above ground pool

• Requires less backwashing and less treatment products

• No risk of seeing a biofilm form, therefore no reduction in performance

•   Adding a flocculant provides exceptional fine filtration

Disadvantages:

​

•   More expensive to buy than sand

​

​

Filter Cartridge

Advantages :

​

• Very limited footprint

• Inexpensive to install

• Easy to install (no need to provide a connection to the sewer)

• Easy to clean with a hose and brush

• Excellent filtration quality

​​

Disadvantages:

​

• Cartridge with limited life: must be replaced every 600 to 1000 hours of use

• Must be disassembled to clean cartridge

• Frequent cleaning (about twice a week in high season)

• Gets dirty very quickly with hard water

• Not compatible with a PHMB-based treatment, with flocculant and certain algaecides.

​

Sand, glass or cartridge, it is important to clean your filtering load regularly and change it maximum every 3 to 5 years for sand and glass, and every 600 to 1000 hours for cartridges.
