Do you know that you no longer need to dose chlorine to keep the pool water crystal clear? Thanks to the Salt chlorinator from Hidro-Water

A pool with a saline chlorine means less skin and eye irritation after leaving the water, gives greater buoyancy, generates less wrinkles on wet skin, and the usual smell from a chlorine pool vanishes because salt chlorinator of Hidro-Water destroys the chloramines that generate it.
There is also a considerable saving in the consumption of disinfectant product because the Sal - Chlorine - Salt cycle is repeated over and over again, and salt only must be replenished with the addition of new water to the pool.


Chlorine solves 3 problems of the pool water:

. disinfects (eliminates bacteria and germs),

. oxidizes (precipitating contaminants when filtering),

. prevents the growth of algae.

In exchange for?   The 3 problems that chlorine generates are:

. strong and unpleasant smell,

. irritation of skin and eyes,

. possible lung diseases and other allergic reactions.

The salt chlorinator of Hidro-Water  is an option that needs less water renewal and is more beneficial to health than chlorine. The technical process of how a salt chlorinator works is based on an electrolytic cycle through which common salt (Sodium Chloride) is separated into chlorine and sodium separately. Next the solar action combines them to start the cycle again. The user, however, only has to worry about adding salt to the pool when new water is added

Advantages of Saline Chlorination

1. Health

There are many medical studies that relate bronchitis, asthma and other pulmonary diseases with the combined chlorine (chloramines) that you can breathe in swimming pools. The system of disinfection by saline chlorination generates, in the production cell, a hyperchlorination that destroys these chloramines.

2. Comfort

The biggest difficulty in maintaining a private pool is usually to control the chlorine level correctly, with all the manipulations involved, such as buying the product, storing it, dosing it and checking it. Without forgetting that it is a volatile product and in liquid state loses properties (concentration), with the passage of the days from its manufacture.

The bath in a pool with a Salt Chlorinator from Hidro-Water is more comfortable, provides the swimmer with greater buoyancy, lower osmotic pressure with which it takes more time for the skin to wrinkle, and does not irritate eyes and mucous membranes as other disinfection systems.

3. Easy to use

The chlorinators are automatic, electronically operated in conjunction with the filter. Some models allow self-control of production, the need for chlorine from the pool, the need for water purification, pH regulation, lights, temperature, cover, save the water analysis of the pool in the cloud ( to read, download or consult), read the values ​​in real time and control the pool from a distance.

4. Security

Reducing the need for chemicals in the pool is the best way to reduce accident risks in it. The risk of burns and poisonings is considerably reduced by not handling some of the products that, by contact or mixing, can cause these and other accidents.

5. Economy

Although it is true that initially the investment of a salt chlorinator is usually higher than in a pool that does not carry it, the costs are reduced by not having to buy chlorine. In addition, less pH regulator is used since the chlorine generated by salt chlorination does not modify the pH. Less anti-algae, less stabilizers and less water renewals are needed.

Well-matched couples with the salt chlorinator

– PH regulator

The regulator keeps the pH level constant spending exclusively the product that is necessary for it. This allows us to have comfortable baths and maintain the effectiveness of disinfection in optimal condition.

– Rx regulator

The Rx regulator is a controller that can be internal or external, depending on the chlorinator model. It allows the chlorination equipment to be even more efficient. This controller shuts off the salt chlorinator when it is not necessary to produce more chlorine (when the pool is not used, when the water is cold…)

– Cristal Water Quimhidro

The use of this revolutionary filter bed in the pool is ecological, economical and safe. The main advantages of this product are:

QUIMHIDRO glass media filter

. Economic: for its long duration it is cheaper than conventional filtering media. The flint, which in a private pool is usually changed every 5-7 years, in the life of 1 load of Cristal Water Quimhidro , it would have been changed at least 14 times. If the filter is repaired, the same load can be reused. The superior quality of filtration with Cristal Water Quimhidro  reduces the daily hours necessary in the filtration of a pool.

. Ecological: keeping the open filtration channels only needs a granulometry, regardless of the filter size. It reduces the pressure needs of the pump because it generates less loss of load, which means less Kw/h of electrical consumption due to reduction of filtering time, or reduction of pump speed. Guarantees at least (usually much more depending on which bed is compared) 35% less need for washes so it reduces the need for water. By not generating Biofilm in the bed drastically reduces the needs of chemical product in the pool. The direct savings in chemical product in the pool are: Algicide = 10% / Chlorine = 30% / reg. pH = 40% / Coagulant-Flocculant = 60%. With salt chlorination, when reducing the needs for water contributions, salt contributions are also reduced in percentage.

. Insurance: filter repairs are no longer an accident risk because Cristal Water Quimhidro It does not puncture or cut like the rest of the glasses in the market.

. Maintenance: Cristal Water Quimhidro from Hidro-Water does not require any maintenance by itself for life,  in addition to reducing the need for maintenance of other equipment in the pool thanks to its high performance. There is no need for filter bed changes in the filters, so these maintenance costs are also saved in the cost of operating the pool.

Ice in Marocco

Advances that we thought that were impossible and nowadays they are not

For sure it’s possible to find ice in some places in Marocco. But it’s well known also the water scarceness of the country.


Thanks to Hidro-Water, it's possible to do a great ice business in Morocco. Good niche market.

We have designed and manufactured a OSMOSIS SYSTEM FOR HIGH SALINITY WATER with a new functionality that makes it even more efficient: the RECOVERY ENERGY SYSTEM (EDR).

It is one of the Hidro-Water projects launched in early 2019: a system that purifies water from a well with very high salinity. Through reverse osmosis we obtain 960m3 of water/day, whose destination is the manufacture of ice


Since the water leaves the well until it can be frozen, Hidro-Water follows the next steps:

1.- PRE-TREATMENT, where the water goes through a system of:

  • Prechlorination
  • Filtering of roughing by filtering bed
  • Dosage of anti-incrustrant
  • Dosage of chlorine reducer
  • Micro-Filtration


We have distributed a membrane rack in one stage to produce 960 m3/day with a high pressure piston pump and energy recovery (EDR). This composition cuts back the final cost of the entire process.

To complete the process we include a displacement and chemical cleaning system consisting of a polyethylene tank, monoblock centrifugal pump and 25 micron filtration.


We add to the process a dosing system for remineralization


We can help you to obtain it.


World Water Day Celebration

But …  if not? Could you live without water?

Hidro-Water joins the International Water Day Celebration thanksgiving the commitment of all the people who work to improve this basic resource.

It is our responsibility to promote the innovations that allow to improve the access to quality water, and to take care of its cleariness.  Efficiency and research conform the path to achieve these goals. The results are avant-garde equipment for water treatment in the industrial and residential area.

Always with an idea in mind:




HVAC 2019 Optimism

Last March the 1st has finished the Air Conditioning and Refrigeration Exhibition HVAC, C & R 2019, in  Madrid. There have been four very satisfying days for Hidro-Water. We have strengthened the trust with our customers, we have made new contacts and we have confirmed the great interest that exists in our equipment exhibited at the Fair, where the Reverse Osmosis ZENIT and the CURVE softener have shined with their own bright light.


According to the organization, this year the number of visitors has increased by 9.7% compared to 2017. There have been 54,781 professionals from 88 countries. It is a fact that could be checked in our stand, where sometimes we were packed. We should also add that we have felt optimism and good expectations for the future among the many visitors who have come to visit us there in our stand in Hidro-Water.

During these days it has been possible to verify the great effort that Hidro-Water has developed in its domestic water treatment equipment. The revolution represented by the ZENIT reverse osmosis equipment has been obvious to the public. It has been highly valued the little space it occupies, the option to be able to place the equipment both in vertical and horizontal position, no storage deposit, its security devices, the LED system to inform of the equipment current state… A lot of advantages that visitors to our stand have been able to check.

Another avant-garde solution exposed in the stand of Hidro-Water has been the CURVE softener system. Its small dimensions have interested many professionals, who know the machine size problem when installing a water softener. With the CURVE the space is optimized and the equipment dimensions are approximately very similar to a washing machine. A very appropriate solution for our current way of life.


As a summary we conclude with a congratulation to the organization for the success of the Exhibition. Good initiatives and synergies have emerged there, therefore it is possible to expose the commitment of Hidro-Water to quality and innovation in water treatment equipment.
