The pool filter is the most important part of the entire circulatory system of one's pool. Correct filter sizing is crucial in determining wether or not a pool's water will be filtered and sanitized correctly. This means that if the correct size of filter is installed together with the correctly rated pump, then clarity of water will be easily achieved and general pool maintenance will be a breaze!

Rhino Pools installs a variety of brands of swimming pool filters including Speck, Quality and Earth Eco.

Domestic pool filter sizes include : 2 bag pool filter, 3 bag pool filter, 4 bag pool filter, 5 bag pool filter (these filters can be ordered with a "side mounted multi port valve" as well as a "top mounted multi port valve" depending on the requirement. If space is a problem then the top mounted multiport valve filter would  better.   

Larger swimming pool filters are also available but would be considered more for the commercial market.

Swimming pool sanitation refers to both visual clarity and levels of microflora, such as bacteria and viruses in swimming pools. The goal of sanitation is to prevent the spread of diseases and pathogens between users. Unsanitized water may also support the growth of algae which will present as a greenish tinge initially, then if left unchecked may completely inhabit the pool water displaying a solid green murky appearance.

A rule of thumb is that the water should be sufficiently clear to permit the main drain to be clearly visible from the pool deck at all distances up to ten meters (eleven yards) in a horizontal direction from the projection of the drain on the pool surface. This, however, is merely to be considered a negative indicator, not a guarantee that the pool water is properly sanitized. Swimming pool water can still be contaminated with microscopic organisms, even though it is visually clear. The United States Environmental Protection Agency therefore issued the recreational water standards a few years ago to restrain the bacterial problem.[1] With the similar objective as EPA, the International Organization for Standardization published the standards of ISO 15553 recently.

Only pools and spas that contain filtered and disinfected water can be considered safe places to swim. Poor pool maintenance may lead to low levels of disinfectants and clogged filters that may place swimmers at risk for diseases and infections. The only way to ensure proper sanitation is to test the swimming pool water with a pool water test kit and fresh reagents.



Filter Unit

A pressure-fed filter is typically placed in line immediately after the water pump. The filter typically contains a media such as graded sand. A pressure fed sand filter is termed a 'High Rate' sand filter, and will generally filter turbid water down to 10 micrometers in size. The rapid sand filter type are periodically 'back washed' as contaminants reduce water flow and increase back pressure. Indicated by a pressure gauge on the pressure side of the filter reaching into the 'red line' area, the pool owner is alerted to the need to 'backwash' the unit. The sand in the filter will typically last five to seven years before all the "rough edges" are worn off and the more tightly packed sand no longer works as intended.
