Swimming Pool Filters: Essential For Keeping Pools Clean
Swimming pool filters are essential for the cleanliness and hygiene of a swimming pool. Swimming in water that is full of germs and other micro organisms can play havoc on a swimmer’s health. These germs and other infective particles can result in serious skin problems, including rashes, and cause ailments like jaundice. So, it is the responsibility of every pool owner or operator to ensure that adequate measures are taken to keep the pool clean on a regular basis and the necessary accessories or equipment are installed. Swimming pool filters should be used to clean the pool water on a regular basis and not occasionally. This will prevent contamination of water and, consequently, the spread of several water borne diseases.
Swimming Pool Filters: Making Pool Water Safe for Human Use
The prime function and utility of these filters is to free the water of any kind of germs or bacteria that can be harmful to humans. It is essential that one chooses the right type of pumps and filters to prevent the build up of slime and scum. These pump filter systems also facilitate the even distribution of essential chemicals like chlorine. Swimming Pool filters can be of various types: Sand, cartridge or Diatomaceous Earth or DE filters.
In case of sand swimming pool filters, a sand bed is used to filter out all the debris collected in the swimming pool. Once the debris is retained on the sand bed, the water flow drops, indicating that the filter needs to be cleaned. In case of cartridge filters, the swimming pool water is filtered through a cartridge and all the debris gets collected in it. These filters are quite easy to clean. Diatomaceous Earth filter are quite useful in filtering out even very small particles. These filters run at higher pressures, as compared to cartridge filters, and can lead to some inefficiency and flow loss.
Maintenance of Swimming Pool Filters
Since swimming pool filters play an important role in keeping the pool water safe and hygienic, they also need to be maintained regularly. Here are certain tips for cleaning your swimming pool filters:
1. In case of a cartridge filter, clean the debris collected in it by using a garden hose. But don’t forget to detach the filter from the whole system before cleaning.
2. Let the filter dry by exposing it to fresh air and sunlight.
3. In case some debris gets stuck in the filter, use a stiff brush to clean it.
