Swimming Pool Filtration System

Water management is critical to maintaining a healthy pool environment. Swimming pool filtration systems require effective circulation to ensure the pool water is regularly cleaned and treated before being returned to the pool.

Water management is critical to maintaining a healthy pool environment. Swimming pool filtration systems require effective circulation to ensure the pool water is regularly cleaned and treated before being returned to the pool.


The job of the circulation system is to recover water from the pool, direct it the pool filter, disinfect it and then re-circulate back to the pool. Using 3D design and simulation tools, Myrtha Pools tests re-circulation systems efficacy to ensure a healthy pool environment can be maintained. Calculations are complex and take into consideration many variables. Our hydraulic simulations in the lab allow us to correctly specify sizes for overflow gutters and floor drains.


Utilizing Computational Fluid Dynamics (CFD) to aid in pool circulation design, involves the simulation of water flow in the pool to help predict the distribution of chemicals and to ensure heated and treated water is distributed throughout the tank.

Our CFD techniques allow us to study and compare the circulation of water during the pool planning period and to make adjustments to the uniformity of distribution of treated water and disinfection products as well as to eliminate stagnation areas.


Strahlenturbulenz system represents an evolution in water recirculation technology and is the recommended system of pool water re-circulation used in Myrtha Pools. The system is based on the Venturi effect which uses controlled turbulence to effectively recirculate water throughout the pool tank. The system eliminates the need for pipes beneath the pool floor and uses inlets or jets built into the vertical sides of the pool walls.

  • High efficiency and efficacy of the system
  • Reduction in re-circulation time
  • Homogeneous re-circulation


The Traditional distribution method recirculates water back into the pool through inlets positioned on the pool floor.

  • Effective, elevated diffusion
  • Conforming to local norms.
  • Homogeneous distribution.

Filtration is the physical process of eliminating dirt, debris, and particulates from the pool water before water treatment and recirculation.

A pool’s filtration system includes, the filter body, pumps, pipes, valves, and a control panel. Local regulations determine the speeds and the time to be allowed to guarantee perfect filtration. Myrtha Pools uses 2 types of filtration systems: Sand or Regenerated Media.


An alternative to traditional sand filtration is a system using regenerative media: filtering media that can be reused more than once when refreshed using specific treatments. The filtration system preferred by Myrtha Pools uses Perlite, an effusive volcanic rock with vitreous structure (similar to obsidian). The Perlite, ground and treated to produce a fine dust, sticks to the filter supports, forming a coating of filtering material. This is a particularly effective method of filtration and can retain particles as small as 1 micron (1 thousandth of a mm).

  • High efficacy of filtration (even, for example, in the case of protozoans)
  • Simple filter management
  • Water saving during backwash, energy and chemical reagent saving


Filters that use sand as a filtering material work with the pressure of a descending flow of water through the sand. The impurities in the water are retained progressively while the water flows through the granular material.

This type of system filters small particles of about 20-30 microns in size. This type of system requires a relatively large space due to the size of the filtration unit. In time, accumulation of filtered material renders the filtering less effective and limits water flow. Periodically, filtration must be interrupted to clean the filter: this is the backwash phase that requires the use of additional water.

  • Easy to use
  • Reliability
  • Filtering material is easily available
  • Chemical inertia of the filtering material
  • Very little maintenance
  • Long lasting
  • Compatible with coagulation/flocculation
