Technology to prepare water for the pools is designed by FTL in cooperation with Jetincotrpс aimed to improve comfort level and operation parameters of the pools to maximum. First of all, the designed solutions are intended to leave behind usually used chlorine-containing agents and, at the same time, to improve bacteriological safety. However, in respect to the current pools, previously used water preparation equipment shall not be demounted, but updated by additional installation of new unit.

1. The main problems, occurring in a period of use of pools, which are subjects for standard water preparation technologies.

Standard technology for preparation water for the pools includes the following scheme for water treatment:

1. рН – correction;

2. Water treatment with chlorine containing agent (routine, periodic and etc.);

3. Filtration of water on a filtering unit with and without use of flocculants.

For long-term use of pools, which are subjects for above mentioned water treatment procedure application, the following procedures shall be applied:

1. Increase of salt content in water, which relate to constant evaporation of containing fresh water. In addition, while the filtering unit operates correctly, loss of water, which discharges, when filters are rinsed and further adding water to the pool can compensate increased salt content only partially. Once a year or even more frequently, half amount of water or even complete amount of water in the pool shall be replaced, but this procedure is expensive enough.

2. Increase of salt content and concentration of organic substances in water of pools results increased hardness, alkalinity and chlorine absorptivity of water. This fact results need to increase doses of рН-correcting substances and chlorine containing reagents as well it results formation on the walls of the pool of a hard-to-remove limy stripe on “water-air” boundary.

3. Use of chlorine-containing agents and related formation of volatile chloroorganic compounds hardly look perfect in the context of view of up-to-date vision.

2. Short description of the offered technology.

This purification technology for water used for the pools, while preserving the filtering unit, provides the following stages:

- installing reverse osmosis system and Silver Ionizer to the line for adding water;

- installing ozone treatment system and UV antibacterial facility on the circulation line (after filtering unit).

Process chart for water preparation is given on fig. 1.

To prepare the best technical and commercial proposal concerning the system for water preparation and purification to use it for any pool in Spain, we need to know the following information:

  - cubature of a pool, m3
  - location of a pool ( inside or outside)
  - maximum number of swimmers , man/day
  - dimensions (plan) of currently used or planned premise to install the equipment

  - currently used equipment intended to supply (pumps) and purify (capacity is m3/h) water
