Filtration System

The importance of pool water filtration.

The way a pool water filter works is that is will pump water from the swimming pool through a barrier (this is determined by the type of pool filter your pool uses (sand, cartridge or DE). This filter will trap contaminants and particulates and hold them within the filter. Our commercial and residential media filters are designed to suit any sizes of commercial swimming pools, aquariums, water parks, water features, and water treatment projects. Poolworld offer various models and specifications together with our custom made service to suit any equipment requirements for your commercial projects.



Innovative double-Layered lateral system benefits uniform movement of water collection and allows more complete and efficient backwashing. Pool water is routed through the media-filled pressure vessel. The media traps particles so small they are undetectable to the naked eye. Over time, dirt accumulates in the spaces between the media particles, causing the pressure in the vessel to rise. This signals you to “backwash” the filter by simply reversing the water flow and “knocking out” the dirt. Always make sure you filter until the backwash water is clear and follow a backwash with a 30 second rinse cycle.

The use of Activated Glass Filter Media inside the sand filter can filter down to 4 micron filtration & last ten years before requiring replacement, will save you time and money.

About Biological Filtration

Biological filtration refers to the breeding of beneficial bacteria inside the biological filtration media in the filter tank. The beneficial bacteria can efficiently convert the ammonia to nitrites , and then to less harmful nitrates. When the water passes through the filter tank, large particle will be trapped by the biological filter media. The small particle will also be blocked by the linked biological filter media. After certain period of time, those particles will be accumulated and the pressure inside the tank will increase. To clear the particles and release the tank pressure, a backwash process of the filter is needed..
