FILTRATION AND CIRCULATION

80% of keeping your pool clean and healthy relies on filtration and circulation.

There are different types of pool filters but most are either cartridge filters or media filters. Most media filters are now using crushed glass as the filter media.

FILTER SIZING

The filter size is based on the volume of the pools water. A pump creating good flow is essential but the pump must be matched to the filter. A flow rate to low will result in the filter not cleaning during a backwash cycle. A flow rate to high could push the water through the filter faster than media can catch and filter the containaments from the water. We aim to turnover the entire pool every 4 - 6 hours.

FILTER CLEANING

The filter will need to be cleaned on a regular basis. Cartridge filters by removing and hosing the cartridge with ocassional deep cleaning with a degreaser and sanitizer. Media filters by backwashing and rinsing. Cleaning frequency will depend on bather load, number of children (sunscreen), number of females (makeup), animals (1 dog is equivalent to 60 people), equipment and surroundings

SANITISATION

Pool can be sanitised manually, semi automatically or fully automatic.

Manual is achieved by adding either liquid chlorine, powder chlorine or tablet chlorine on a regular basis

Semi automatic is usually via salt chlorination which produces chlorine gas directly into the pool water as the water passes over a electronically controlled cell. Chlorination levels in the pool will alter with use.

Fully automatic will use either a salt chlorinator or liquid chlorine pumps controlled by an electronic controller that has probes in the water to test levels and produce as required
