Plant room filtration systems are often talked about, but they wouldn’t work without pipes and inlets and drains in the swimming pool. By using this hydraulic network, the pool’s water is kept clean for swimming. Thus, a hydraulic drawing is essential.

How does pool filtration work?

The pool water always contains impurities and suspended particles that need to be removed. Therefore, swimming pool pumps filter the water by sucking it through the skimmers and bottom drain then sending it to the filter. Return inlets allow water to return to the pool after passing through the filter.

Overflow pools have specific characteristics

There is a slight difference in the circulation of water in an negative edge pool or a zero edge pool. Weirs are used to drain water from the pool. Water flows through gutters into a catch basin (or balance tank) where it is pumped out. The filtration system is the same as for a traditional pool; it just takes placing the valves and check valves correctly. A filtration plan is therefore very useful for an overflow pool construction project.

Hydraulic circuit of the pool

The pool parts and piping in the pool itself

In general, these are located in the walls or the bottom of the main pool depending on the pool’s specific features. PVC pipes are connected to them and lead to the plant room where the filtration system is located. Inlets are calculated based on the filter pump’s flow rate and the pool’s volume.

For the construction of an overflow pool, the hydraulic layout  should include information about the position of parts to be sealed and the routes taken by all pipes. It ensures a good balance of flows.

The pool equipment in the plant room

The equipment in the plant room consists of the filtration unit and, if necessary, a water treatment system, a pump for endless swim equipment, a spa bench, or a heat pump bypass. The more equipped the vanishing pools are, the more essential an accurate filtration design is.

An overview of the main swimming pool filters

The professional should be able to guide the customer on the best filtration unit in light of the swimming pool size, pollution around the pool, and budget. There are different types of pool filters; a filter’s rating is an important consideration when choosing one. It measures  their ability to remove particles of a certain size from water. These diameter dimensions are expressed in micrometers.

Sand filters

It is the most common filter and is used in both above ground and inground  pools. Depending on the grain size of the pool sand, the filter rating ranges from 30 to 50 micrometers. With hard water, clogging occurs fairly frequently and scales up fairly quickly. Washing the filter increases water consumption, so be careful.

The cartridge filter

Above-ground pools often have them installed. Cylindrical in shape, the cartridges have pleated surfaces for filtering. Simply spray water on the cartridge to maintain it. The filter rating is around 20 micrometers.

The diatoma filter

In diatomaceous earth filtration, fossilized hard-shelled microalgae called diatoms are used. This filter is capable of filtering up to 5 micrometers, but it is expensive to install and its filtration capacity is low. The use of flocculants in case of turbidity is prohibited as well as the use with biguanide treatment. After the pressure gauge needle reaches the orange line, the filter must be washed and discharged to the sewer is prohibited.

Improvements to swimming pool sand filters

A different filtering medium is substituted for the sand. Recycled glass or Zeolite is used to fill the tank. Glass filtration has a better quality; it ranges from 1 to 5 micrometers

In summary, a low filter ranking allows for more efficient water filtering, making pool maintenance easier. The pool filtration unit must, however, be installed properly.

What are the benefits of an infinity pool filtration design?

Schéma local technique

Taking into account the type of filter and the filtering mass is not sufficient to ensure good pool water quality. Besides these factors, there are others to consider:

  • Let’s discuss the pool turnover rate first. In summer, all the water in your pool must pass through the filter twice daily (around once every five hours). By knowing the pool’s water volume, the pump power and filter size can be determined.
  • For a perfect mixing of the treatment and maintenance products, the position of each inlet is crucial.
  • For a perfect water circulation, the diameter of each pipe is also important.
  • Well-thought-out piping design can minimize some pressure losses by reducing the number of fittings.

Obtain professional assistance when it comes to implementing a filtration system

Infinity pools and zero deck pools require a filtration design showing the piping layout connecting the pool to the plant room, the location of all the parts inside, and installation designs for the pumps, filters, and optional devices.  The position of each valve, check valve, or pipe is crucial in the plant room. Water circulation can also be improved by limiting the number of elbows.

There is nothing more satisfying than owning an overflow pool. To enjoy clean water, you need an efficient filtration system. It’s strongly recommended to hire a professional to design your pool filtration system. For pool renovations, it is also crucial.

The filtration drawing allows your infinity pool to function better beyond aesthetic considerations. An expert’s knowledge and expertise are essential when designing a hydraulic pool circuit. For infinity pool filtration design, who should you contact ?
