A swimming pool filter system can be either a pressure or vacuum type of pool filter. The filter media for these diverse types of swimming pool filters are made of either...
These are the types of pool filter media that are the most used in the swimming pool and spa industry today. A pressure type swimming pool filter is a closed tank that is located or installed downstream from the swimming pool pump used for your circulation and it is inline win line water flow.
The output head pressure of the swimming pool pump is the force that is used to drive the water from your pool through the pool filters that are installed on the system.
As the water is forced through the swimming pool filters, the suspended particles are trapped in the bed of the media of the filters.
Subsequently, as the swimming pool filter media gets packed with the suspended particles from the water being passed through it, the influent pressure (water coming into the filters) increases. As a result of the increase in influent pressure, the effluent pressure (water exiting the filters) is reduced.
Vacuum pool filters on the other hand, are placed before the swimming pool circulation pump. This type of swimming pool filter is normally set up or installed where they are openly exposed to the atmosphere.
The suction side of the swimming pool pump creates the force that will pull the untreated water through the filter media. As the media of the filters trap the suspended particles, the vacuum pressure is increased causing a reduction in water flow.
There are three types of swimming pool filters that are used in the swimming pool and spa industry. They are listed below. The purpose of all swimming pool and spa filters as we can see, is to clean debris from the water and help maintain a healthy and inviting pool.
Without a proper swimming pool filtration system installed in your swimming pool, your water will be dirty, and quickly contaminated.
All of which is achieved through your swimming pool or spa filtration process. Each of the different swimming pool filter systems use a similar process in the water forced mechanically through the media of the swimming pool and spa filters. The debris in the water is then trapped or filtered out and the water is returned to the pool.
When an engineer decides on a type of swimming pool or spa filter for a particular pool water system, they must take into consideration the space and the budget of you, the client. Some of the swimming pool filters that they normally choose from when constructing a new mechanical system include...
Sand swimming pool filters are considerd permanent pool filters because their media last for an exceptionally long time. This period could be anywhere from 5 to 15 years before the silica sand has to be replaced in the filter.
The primary operation of all swimming pool sand filters is the same. Water is forced from the top to the bottom of the pool filters. The sand swimming pool filter media traps the suspended water particles as the water passes through the sand media.
As suspended water particles attached themselves to the edge of the fine silica sand, they cause the gap between each of the sand grain to become smaller and smaller. As a result of this, the smaller particles such as body waste, lotions, hair, and dirt are trapped in the sand media.
This process creates a fibrous maze that eventually filters out the smallest particles in the water coming from your swimming pool. Unfortunately, this process also has some downfalls. This causes pressure to build up in the swimming pool filters and a reduction in your water flow.
This is an indication that your pool filters must be cleaned to improve water flow. The cleaning of the swimming pool sand filter is achieved through a process known as backwashing. Overall, sand filters are the most economical and easy to maintain; however, they are the least efficient.
They are also environmentally friendly, and they require little to clean. The only downfall is that these types of filters these types of filters for it to be cleaned. The filtering efficiency of a cartridge pool filter is 10 - 15 microns; thus, making these types of swimming pool filters better than that of sand swimming pool filters.
Diatomaceous earth filters are considered the most efficient swimming pool filters because they catch the smallest particles; thus, providing you with the cleanest pool water possible. However, there is a downside to this type of filtering unit, they are both expensive to buy and maintain.
The filtration of your swimming pool water is extremely important because of serious water contamination which can cause illness. If you don't have a good swimming pool or spa filtration system installed, you are asking for trouble. Keeping your family or guest healthy during the use of your swimming pool or spa, not only depends on your pool disinfecting or sanitation! It also depends heavily on a professionally installed swimming pool filter.
A swimming pool filter has to have the right filter media for the job that it has to do!
