Equipment for pools
To ensure operation, cleaning and pool maintenance a whole range of engineering technological systems is used. Even at the design stage, all the necessary equipment for the pools is selected, its location and installation are thought out and calculated. Depending on the functions performed, the equipment is divided into several groups. Some elements are engaged in pumping and supplying water, others – its heating and disinfection, while others serve to facilitate the use of the pool.

Equipment for pools can be divided into primary and secondary based on the importance of its purpose..
Equipment for frame pools is not much different from stationary. For frame pool also need filters, pumps, disinfecting devices. It only consists of a metal frame covered with PVC film, and is most often used in the country or in a country house in the summer season.
The scheme of the pool equipment clearly shows the location of all the elements below and described.
How to equip the pool
Basic equipment is designed to provide basic pool functions. It is responsible for filling the bowl with water, circulating it, filtering, disinfecting and draining.
Water filtration systems
The filter installation in the pool is necessary so that the water always remains clean, transparent with a blue tint. If you do not use it, then the stagnant water will become cloudy over time, it will begin to “bloom” like a closed pond or swamp, and microorganisms will multiply uncontrolled and unhindered. The filtering station cleans water from dust, dirt, leaves, microorganisms and everything that could attack the outdoor outdoor pool. In addition, it controls the acid-base balance of water and the level of iron. Deviation of this indicator from the norm can harm the skin of a person or the details and elements of the pool itself.
If the pool is small, then water filtration must be carried out continuously. In a large pool, filtering can be carried out once a day. The power of the filtration system and the number of pumps is calculated based on the volume of water.
The filter unit consists of a pump for circulating water and a filter tank. Depending on the cleaning element, the filters are divided into single-layer, multi-layer and cartridge.
Single layer filters They are a fiberglass-reinforced polyester filter chamber containing quartz sand. Sand filtration purifies water from small elements and is very easy to maintain..
Multilayer Filters cleaned with hydroanthracite and sand of various fractions. Allows to get rid of turbidity, extraneous smacks and smells, as well as water-insoluble particles.
Cartridge systems are filtered with various fillers: granular or briquetted coal, polypropylene fiber and other fillers. You can choose a cartridge with an individual composition for the preparation and change of water quality. In addition, elements of such systems are easy to replace..
Heat exchangers and electric heaters
For comfort and convenience, the water in the adult pool should have a temperature of 25-26 ° C, and in the children’s pool – about 30 ° C.
Three methods are used to heat water to the required temperature:
- Heat exchangers;
- Flowing electric heaters;
- Solar collectors.
Heat exchanger It is connected to the heating system of the house. It consists of a flask with a coil inside, in which the coolant runs. Water washes the coil outside and heats up. The power of the heat exchanger is selected depending on the volume of water. Maximum power is needed only at the very beginning of heating, when the pool is filled with cold water. The heat exchanger is connected after the pump and filter stations, but before the chlorination system. If the water is too chlorinated or marine, then titanium heat exchangers are used..
The advantage of using heat exchangers is the ability to heat a large volume of water and save on electricity if the heating of the house is based on gas fuel.
Flowing electric heaters They are used to heat a continuous stream of water and are installed in small rooms. The case of this device is made of plastic, titanium or stainless steel, and the heater is made of a special alloy of stainless steel. The power of the electric heater is selected depending on the volume of the pool and can be from 3 to 18 kW. Overheat protection relay, pressure sensor, thermostat and flow sensor are already included in the electric heater kit, and this is an indisputable advantage.
Solar collectors heat water using solar energy. They consist of modules, each of which can heat up to 30 m3 of water. Installation of collectors is very simple and does not require special knowledge..
Pumps and their types
To maintain a constant circulation of water in the filter unit, a pump is used. It is selected depending on many factors: the volume of the pool and its purpose, type of filtration system, distance of water supply and many others.
There are self-priming pumps, which, being above the water level, can raise it up, and pumps with normal suction. Some pumps have a prefilter, while others do not. Pumps with a prefilter are used in filter installations, and pumps without it are used for attractions, waterfalls and hydromassage. For normally suction pumps, it is imperative that the pipe diameter is correctly selected and that water intake is unobstructed..
Pool Control Units
Control units monitor and regulate the operation of almost all elements of the pool:
- turn pumps on and off, preventing idle dry running and overload when the filter is clogged;
- protect electric heaters from voltage drops in the network and phase imbalance;
- keep the chemical parameters of water normal;
- smoothly turn on pumps for attractions, waterfalls, air massages, ground geysers, etc..
Control panels are programmed manually for a specific operating mode..
Water disinfection equipment
Chlorine dispensers the most common water disinfection option. It is mounted in the pool system and independently controls the level of chlorine in the water. Using the handle you can adjust the dosage.
Ionizers purify water with copper and silver ions. This reduces the need for chlorine..
Ozonizers for cleaning and disinfection of water began to use relatively recently. But this method has gained popularity, since the water after the ozonizer is clean and very beautiful.
UV installation – a relatively new way of disinfection. Viruses, fungi, algae and unicellular organisms die under the influence of ultraviolet radiation.
Pipes and nozzles, drain, skimmers
To connect the basic elements of the pool and ensure their operation, pipes, nozzles and drains are needed. They can be made of plastic or stainless steel. Plastic is cheaper, and stainless is more durable..
Skimmers necessary for taking water from the pool surface and filtering from dust and dirt.
Additional equipment for pools
Additional equipment is necessary to ensure the convenience and comfort of using the pool..
These are all kinds of devices for entering the pool, hiding it for the winter, regulating the characteristics of indoor air, etc..
Stairs and handrails
The function of the stairs and handrails is obvious. Most often they are made of polished stainless steel. In the deep pools, the stairs are mounted upstairs, and the lower part is screwed to the wall. Stairs provide a safe descent into the pool and climb out of it.
Pool lighting necessary not only for beauty. It allows you to use the outdoor pool in the dark. Spotlights and fixtures are mounted in the walls of the bowl.
Protective coatings for pools
Pools cover at night, winter, or simply when they leave for a long time, so that dirt, leaves and much more do not fall into it. In addition, evaporation from the indoor pool is reduced..
Attractions: slides, waterfalls, geysers
Equipping a pool for children or just having fun, you can use a variety of attractions: slides, geysers, waterfalls and much more.
Ionizers, air driers
Dehumidifiers and air ionizers are used to change the level of humidity in the room where the pool is equipped. Air is drained for greater convenience..
Installation of equipment for pools
Installation can only be carried out according to a pre-prepared project. It is necessary to assemble the equipment, check all threaded and adhesive joints, couplings, faucets, etc. Pour water into the pool and turn on the filter unit in the “Rinse” mode, and then switch to the “Filter” mode. If leaks are not visible, then the installation was successful. Installation of equipment on a stationary pool is best entrusted to specialists, and the installation of a frame pool can cope independently.
