Pool skimmer

These impurities remain suspended on the surface, affect the appearance of the water and are not always removed by the conventional vacuuming process.

[4] In the United States and Portugal, the use of skimmers in the construction of swimming pools is mandatory, regulated and standardized by competent bodies.

The internal parts of the skimmer are accessed from the pool deck through a circular or rectangular cover, approximately one foot in diameter.

The waste material is trapped within one or more sequential skimmer basket sieves, each with a finer mesh to further dilute the size of the contaminant.

Ultimately, the sand screen can be backwashed to remove smaller trapped organic debris that otherwise leaches ammonia and other compounds into the recirculated water.

The sieve baskets are easily removed each day for cleaning, as is the sand unit, which should be backwashed at least once a week.

This has the advantage of cleaning the bottom of the pool and slowly moving the sunken inorganic debris into the main drain, where it is removed by the circulator basket screen.

In a properly constructed pool the circulation of water caused by the way it returns from the back-dilution system will reduce or even eliminate the need to vacuum the bottom.

If the pool is designed and operated correctly, this circulation is visible and, after a period, reaches even the deepest end, inducing a low-speed vortex over the main drain due to suction.

Correct use of return jets is the most effective way to remove disinfection byproducts caused by deeper decaying organic debris and bring them into the back-to-back dilution system for immediate disposal.

Companies cannot sell a mineral disinfectant in the United States unless it has been registered with the US Environmental Protection Agency (EPA).
