How to clean water for bathing: a review of how the outdoor swimming pool filtration

When installing the outdoor pool first thing innecessary to solve the problem of the purity and safety of water. The aquatic environment is the habitat of thousands of microorganisms, which can get rid of only by means of special equipment. Closed stationary pools still under construction provides a powerful filtering systems, around the clock supporting the circulation and purification of liquids and for domestic outdoor structures are provided filters for swimming pools at the power, but easy to install and maintain.


Why do you need a filtration system?

Natural water rarely has the qualities,ideal for healthy swimming, so there are many ways to clean, such as chemical disinfection, Manual cleaning, ozonation and filtration - the most popular way for a country of use.

filtration system

It is impossible to enjoy a relaxing holiday in fullAs if the water is dirty and dangerous to health, so together with the purchase of an inflatable structure or frame, as well as during the construction of a permanent reservoir in the yard of a country house, take care of installing the filtering system

Clean water should be out of its dependence onwater supply source. Do not assume that tap water is rich in lime and iron particles, and the liquid from the well or from the surface of the lake is flawless in its characteristics. The "living" water is increased likelihood of bacteria to grow, as completely absent chemical treatment. Moreover, water quality is sharply reduced due to the ingress of large particles of dirt and dust on the uncovered surface of the water basin.

Water for bathing in their characteristics should bebe a close analog of drinking, as in the time of the adoption of water treatments, it gets in your eyes, ears, mouth, nose and constant contact with the skin. The quality of the liquid can be determined even without special equipment: it is transparent (you can see the image, or cracks in the bottom of the pool), no odor caused by microbial decomposition, and brown or green.

Electronic tester

To determine the pH or the presence of chlorine, you can use a set of tablets, strips, or more expensive, and accurate devices - modern electronic tester

However, some of the properties to determine "the eye"extremely difficult - this refers to the content of salts in its composition or the level of acidity. To maximize the purity using processing techniques such as:

  • multi-mineral purification;
  • disinfection;
  • advocacy;
  • conditioning;
  • softening composition.

Filters are used at various stages of purification,since mechanical harvesting leaves from the water surface with special devices, finishing distillation and neutralization of acidity at the finish stage.

Types of filters for public pools

Although various fillers and distinguishingSpecifications, all filters have the same purpose - to purify water from harmful substances, the maximum delay and unnecessary pollution particles. As filter layer use bulk material grain structure: sand, anthracite, gravel or crushed pieces of diatomite.

Type # 1 - sand device

With the availability of sand filter it canbuy everyone, the minimum value of current models - 4800 rubles. Of course, such devices are designed for relatively small amount of filtered water and suitable for cleaning and inflatable compact frame designs. For tanks larger volume provides powerful units costing up to 1 million. Rubles, but for home use expensive production models are not needed.

sand filters

Sand filters are compact, streamlinedshape their body is protected from the effects of natural factors. Such devices are installed right next to the pool, additional pads or protective covers do not require

When choosing a sand filter notefiller. It may be only sand, sand and gravel particles, as well as inclusions or anthracite carbon. The more diverse filler, the higher the level of purification. The quartz sand must be completely replaced every 3 years, but there are options with a rare replacement, for example, glass sand pour only once every 5 or 6 years.

only one layer is filled in a simple designsand (0.5-0.8 mm), more sophisticated devices - 3-5 layers of different fractions. First, water passes through the large crystals, complete cleaning in fine sand cushion. additional absorbent layer may be present in expensive models.

Each type of material has its own characteristics. For example, granular anthracite, almost 90% consisting of carbon, differs sufficiently large and spiky beads. Unlike sand, they do not form a dense cushion, so filtering occurs during the minimum loss of load, but the cleaning rate increases.

Driving sand filter

The principle of the sand filter can be seen in this diagram: water gets inside the unit, it passes through the layer of mineral particles and is already cleared

What should I do if the filter is clogged? This will happen after 1-2 weeks of active use of the pool. Each device incorporated feedback cleaning function, which would require additional water. Owning their own wells do not worry, while the centralized water supply system users there more waste of budgetary funds.

Sand and other fillers soldspecialized shops, 25-pound bag of quartz material costs about 400 rubles, glass - about 2 times more expensive. This filter can even build your own! How do you look at the video:

Type # 2 - diatomaceous system

Manufacturers diatomite filtration plantsIt claims that the use of fine powder (diatomaceous earth) can achieve maximum purity water. Let's try to understand the technical characteristics of this type of filter and understand it is worth buying for the holiday pool most expensive equipment.

diatomaceous earth

Diatomite which has another commonname - diatomaceous earth is a sedimentary rock. At its core, it is pressed fossilized diatoms, on 95% consisting of silica

The fine particle fraction cleaning delaystiny dirt up to 1 micron, which is a huge advantage over the sand analogs, although in other respects the principle of diatomite devices is no different. Filler layer is in the self-cleaning steel elements covered with polypropylene. Water passes through diatomaceous "cushion", cleaned and displayed back to the pool, enriched with silicon.

Hayward Pro Grid

One option diatomite filter for outdoor pool - model Hayward Pro Grid: operating pressure up to 3.5 bar, the filter diameter of 660 mm, capacity 11 m / h, the cost - 60 thousand rubles?.

The benefits of silicon water a lot said and written. Experts say that it has a set of useful features:

  • neutralizes chlorine compounds;
  • destroys pathogens;
  • precipitates the heavy metals;
  • prevents the growth of algae;
  • It has a strengthening effect on the human body.

Thanks to a thorough cleaning and the "magic"properties of the silicon water is no need for additional chemical disinfection. Thus, overpaying for diatomaceous device other than perfectly purified water, you get an additional bonus in the form of health-improving effect.

Type # 3 - compact cartridge installation

If you are not able to carry out constantreverse rinsing filters, and water in the pool relatively clean and does not require a thorough disinfection, buy an inexpensive cartridge filter. It is a small oblong install a bulb with a very simple internal structure. Under the hood is a compartment for a replaceable cartridge and a plastic garbage bag. Water seeps through the filter material of the cartridge, and coarse dirt and fine particles settle to the bottom, collecting in the bag.

cartridge filter

When buying a cartridge filter, pay attention to such factors as the density and thickness of the filter inserts, power or filtration rate, the type of collector (bag for garbage collection)

There are many types of cartridges, and differentappearance and characteristics. For example, the carbon elements perfectly eliminates odors, and insert the ion exchange resin destroy bacteria. But the pool is preferable to use a special consumables to the polyphosphate salt.

Cartridge filter for swimming pool

One of the main advantages of the cartridge filter - easy maintenance. Replacement takes a minimum of time, and when washing a strong porous material to clean very quickly

Sooner or later, the cartridge unusable andbag completely clogged debris. Cleaning is simple: the cartridge should be rinsed plates under running water, and a bag from dirt and return to the place. After several cleaning procedures necessary to replace the replaceable element. It can be bought in a specialty store for the price of 125 rubles. Manufacturers recommend changing cartridges as they wear, that is, the replacement can happen in a week and a month. For hygienic reasons, it is better not to delay the purchase of a new element.

How to choose a filter pump is the right?

All filters species may be an integralof the filter pumps - devices for organizing the circulation and purification of water in the pool. The equipment is equipped with a powerful engine with waterproof insulation, which allows the movement of water. Filters for primary or deep cleaning included, and some are sold separately. It is important to take into account the capacity and speed of performance, not to mistakenly fitted with the pump too weak effective filter, or vice versa.

The scheme of installation of the pump

In rare cases, the filter pump is lowered into the ground, and mounted above the water level. Maximum lifting height - 2 meters

Most of the self-priming pump isbuilt-in filters for cleaning slightly dirty water, more thorough treatment requires the purchase of additional equipment or chemical disinfection. The equipment is placed in a special container and buried in the ground next to the pool is half full or so that remained unimpeded access.


Filter pumps are equipped with a primary pre-filter - a plastic mesh basket with fine mesh to retain large debris: leaves, twigs, grass

When buying pay attention to the limit. Most of the models perform the functions under the following parameters:

  • t? air - up to 60 C;?
  • t? water - up to 40 C;?
  • pressure - 2.5 (3.5) bar.

The preferred model with the continuous operation mode.

Intex systems

Known Intex company produces ready-made kits - inflatable and frame pools + filter pump with salt water system which ensures the safety of swimming without the use of chlorine

Conventional circulators and centrifugal pumpscarried out without the possibility of pumping water to clean it, so you need to buy an additional filter, and it is better if they would be two. The first is used for pre-filtration and equipment protection, it produces a screened abrasive or long fiber fragments. The second more thoroughly cleans the water from the suspension and fine particles and ensures the safety of swimming.

What is a skimmer, and whether you need it?

A simple but useful device - Skimmer -able to cleanse contaminants from large to 8% of the water in the pool, so it is often used in conjunction with a filtration equipment. On the surface it looks like a plastic or steel tank with drainage in the lower part, the upper part is provided with a hole for water abstraction.

Some skimmers models have advanced features:

  • collect garbage from the water surface;
  • are a kind of "beacons" to determine the depth and water level;
  • provide equipment for chemical cleaning.

There are two types of skimmers: attachments and embedded. both types, but their choice depends on the design of the pool is suitable for swimming pools open type. For the stationary tank is better to use the built-in system with water intake, located along the ledges, but for the inflatable models and frame preferably mounted devices, which have a special attachment. There are exceptions when a monolithic pool is installed without purification system - coarse filtration can be carried out also by means of attachments.

Built skimmers

Built skimmer system does not prevent water cleaning and bathing water games: water inlets are arranged along the edges, and release the reverse occurs at the bottom under water

Skimmer for inflatable pools

The simplest device for the pool - skimmer trap. Used to collect large and small debris floating on the surface of the water: dry grass and twigs, leaves, hair

Installing skimmers for inflatable curtainpools and frame structures is very simple: an adjustable clip is attached directly to the rim, and the filter is immersed in water, placing it on the surface or just below. When installing any kind of devices must be considered the dominant wind direction to avoid creating dead zones and skimmers cover the entire area of ​​accumulation of debris.

Thus, when choosing a filtering systemguided by the type of pool, its size and the volume of water. For compact designs inexpensive enough sand or cartridge filter with a pump, to a large outdoor swimming pool in the yard necessary equipment, including more filters, powerful pump, heating system and a control unit.
