Understanding Pool Filtration Systems And Their Advantages

By Tammie Caldwell


Responsible for keeping the entire volume of water in a swimming pool clear and safe to swim in, a filter is one of the most important machines in the operation of a pool. It eliminates dirt and debris which make the water cloudy and can encourage algae and bacteria growth. Both inground and above-ground pools can be equipped with one of several styles of pool filtration systems, each with its own benefits to the user.

The basic function of a filter, regardless of its design, is to rid the water of impurities so it stays clear and does not pose a threat to the health of the swimmers. All filter types operate on the principle of using a barrier of some sort to physically remove debris from the water. These different models differ from each other in price, upkeep, and in the advantages they provide.

What is referred to as the filtration "system" includes both the filter itself and the pump. The latter pulls water from the pool into the former, where contaminants are filtered out, then the clean water is pumped back into the pool. Well-made systems can last for years, and ultimately they will help reduce the time and money one spends on the pool's upkeep.The basic types of filters are the cartridge, sand, and diatomaceous earth (DE) models, which are all compatible with inground and above-ground pools.

Most common of all types are the sand filters. This kind features an in-filter sand bed as its filtration site. Particles which are 20 microns in size will be trapped. Cleaning is done by reversing the flow of water through the unit, and generally the sand can be used for several years. They are a popular choice due to their reasonable pricing and easy operation.

Another affordable, low-maintenance alternative is the cartridge filter. The filtering element in this design consists of a removable cartridge which can remove particles as small as 10 to 15 microns. Economical, they have the added advantage of being easy to maintain by using a garden hose or a filter cartridge cleaner to clean them out. In general a new cartridge is needed for each swimming season.

DE or diatomaceous earth filter systems offer the ultimate in speed and efficiency. They can eliminate the very smallest particles of debris which are only 3 to 5 microns in size, and work quickly to produce crystal clear water. The substrate contained within them, known as diatomaceous earth, is a porous, natural rock sediment which has been ground into powder. While typically more expensive, this approach does offer superior results.

With any filter design, it is a good idea to choose a model with a larger capacity than the minimum indicated for the size of the swimming pool. This will mean one has to spend less time cleaning the system. Also, it's helpful to opt for a set-up with minimal pumping, as this will reduce costs for electricity needed to run it.

Basically, the filter one selects for their pool should reflect their priorities. If the user's primary concern is a simple design which needs minimal maintenance, either a sand or cartridge filter would be suitable. Whereas those who are focused mainly on having the clearest water possible, should go for the DE filter.
