How does the pool filtration system work?

Posted by John Smith on September 19th, 2019

All pools have a filtration system to keep the water clean, free of algae and bacteria. The two most important components of the treatment plant are the filter and the pump.

How does the filtration system work?

The Hayward pool pump, using an electric motor, turns a turbine, sucking the pool water through the skimmer and sump.
Water is propelled into the vacuum chamber, which is the pump housing.

The water passes to a tank or tank that contains a special filtering material which performs the physical treatment (filtration) of the water.

Most of the impurities contained in the water are retained in what we call the filter bed.

The diffuser, located inside this tank (filter), helps eliminate air bubbles.

We return the clean water to the pool, completing a cycle. A cycle is the passage of the entire amount of water in the pool through the filter. The duration of this process (cycle) will depend on several factors:

- Pool size (amount of water to filter).
- Pump power (amount of m3 that can aspirate every hour).
- The capacity of the filter used.
- The filter

The filter is the main mechanism for cleaning and purifying water, and performs a crucial task to keep the water crystal clear and suitable for bathing. Sand filters are the most common and, at the same time, are also the ones that require less maintenance. Water is cleaned by passing through a sand deposit. As the water is filtered, the dirt particles get trapped in the filter bed before the water is returned to the pool.

The pump:

The Hayward ecostar pump is the other essential element for the pool filtration system. Most of the pumps are self-priming, which means that when they are started, they will be filled with water without the help of the user. 

The Hayward super pump can be of different powers, depending on the size of the pool and the number of liters of water that must pass through the filtration system. This will determine the electrical power of the pump to choose.

The pool Hayward tristar pump has a motor that spins at a high speed. At the other end, there is a turbine (impeller) that is activated by the pump motor. The housing, also known as the vacuum chamber, is filled with water, creating a vacuum and allowing the pool water to circulate.
