Filtration plays an indirect role in disinfecting swimming pool water.
Although it does not play a disinfecting role, pool filtration does help disinfection by eliminating suspended solids and micro-organisms from the water.
As it reduces pollutants in the water, it enables disinfectants to be more effective.
- Filtration eliminates particles, organic matter, algae and bacteria attached to debris.
- It prevents these impurities from consuming disinfectant unnecessarily.
Filtration accounts for around 80% of pool cleaning and therefore of bathing water quality. An efficient filtration system will therefore reduce the use of chemicals.
The problem: the filter clogs up naturally
Whatever the type of filter, the operating principle of a filtration system is similar: the pool pump drains impurities into the filtration system, removing the dirt from the water before returning it to the pool through the discharge nozzles.
The filter will therefore gradually clog up as it operates.
Some filters have a pressure gauge that indicates the filter’s internal pressure. If the pressure gauge indicates an abnormally high pressure, the filter is probably clogged.
It is therefore vital to clean your filtration system regularly.
The solution:
Clean and descale the filter of your pool with HTH FILTERWASH, compatible with sand filters, diatomaceous earth and salt water chlorinators.
- Tinted liquid for easy rinsing
- Excellent solvent and detergent properties
- Highly effective against limescale deposits
- Graduated bottle or jug for easy dosage
How to proceed:
➽ Sand Filters
- Open the filter.
- Drain the filter until the water level is at the sand level.
- Pour the product directly into the filter.
- Close the filter.
- Leave to work for at least 1/2 a day, or overnight for example.
- Backwash the filter until the colouring in the control indicator disappears (when possible).
- Rinse the filter.
➽ Diatomite filters or cartridge filters
- The product should be diluted in the proportion of 1 litre to 10 litres of water.
- Dip the items to be cleaned into the container containing the solution.
- Leave for at least 2 hours.
- Brush and rinse the parts.
➽ Cleaning your salt chlorinator
HTH FILTERWASH can also clean the cells of salt electrolysers.
- Dilute the product at a rate of 1 litre in 4 litres of water.
- Soak the scaled electrodes in the prepared solution until the scale has completely disappeared (2 to 3 hours).
- Rinse the electrodes with plenty of water until the foam has disappeared.
Our advice:
- Check regularly that the filter is not clogged
- Clean the filter
↳ when you open the pool in spring
↳ regularly during the season
↳ when you winterise the pool - Adapt the filtration time to the number of people using the pool and the water temperature.
