POOL WATER MAINTENANCE

Water is vital. It makes up two-thirds of our body, preserves our vitality, and gives us strength. We don’t need water just for life; it can also provide us with a lot of fun in our pool. Pools are precious oases that offer us a place to relax, stay active in our free time, and take care of our health in this fast-paced and demanding lifestyle.

pH value

The pH value is one of the most important factors in the chemical treatment of water. Regardless of which disinfectant is used, it is first necessary to adjust the pH value to the optimal range, which is between 7.2 and 7.6. A low pH value (below pH 7) gives the water an acidic character, leading to corrosion of metal parts in the installations, heat exchanger, and filter. This can result in the deposition of metal oxides on the pool surfaces, which may appear as stains. A high pH value (above pH 7.6) gives the water an alkaline character, promoting the formation of limescale on the pool surfaces. A high pH value also causes water to become cloudy, giving it a "milky" appearance. The filter fills with impurities more quickly, and deposits form on the pool surfaces and equipment. Additionally, at elevated pH levels, disinfectants are less effective, which leads to problems in maintaining hygienically perfect water. The pH value of pool water is adjusted using pH regulators, which can be in liquid or solid form.

Disinfection

Along with regulating the pH value of water, the most important treatment for pool water is disinfection. The water in the pool must be clean, colorless, and hygienically flawless. Drinking water, which is typically used to fill the pool, meets these hygiene requirements. However, swimmers and environmental factors introduce impurities, fungi, and bacteria into the water, which multiply very quickly, especially at water temperatures above 25°C. Larger particles of impurities are removed using a pool vacuum and filter, while bacteria must be neutralized using oxidation agents. Chlorine is the most commonly used oxidant in various forms: Sodium hypochlorite (liquid), Calcium hypochlorite (granules or tablets), and organic chlorine (granules or tablets), where isocyanuric acid is used as a chlorine carrier, preventing chlorine from evaporating quickly due to sunlight and heat. It does not alter the pH value of the water, is fully soluble in water, leaving no mineral deposits on pool walls, allows for long-term storage, and is relatively safe and easy to use. Regardless of the chlorine form, we must ensure that there is enough chlorine in the water to kill bacteria and maintain perfect water quality. Chlorine products have a resistance property, meaning that after their initial disinfecting action, a certain amount of free chlorine remains in the water until it is completely consumed or degraded. The residual chlorine content in the water must range between 0.3-0.6 mg/l.

Prevention of Algae Formation

Algae are the simplest plant organisms whose growth and development require water, sunlight, warmth, and, of course, nutrients. Pool water meets all of these conditions. Additionally, insufficient water filtration and poor circulation also favor algae growth. Algae themselves are not a source of infection, but they provide an ideal substrate for the development of other microorganisms. Dead algae become food for bacteria. The early signs of algae formation manifest as a slimy and slippery coating on the pool walls. Later, visual changes appear in the form of cloudy water, unpleasant odors, and green (or black) spots on the walls. Algaecides are substances used to destroy all types of algae.

Clarification

Over time, and with the presence of more swimmers, a larger quantity of dissolved organic micro-particles accumulates in the water. Water containing these types of impurities becomes cloudy and takes on an unpleasant milky appearance. Weaker and shorter filter operation promotes the occurrence of water cloudiness. Since these micro-particles are too small to be collected by the filter, they need to be coagulated with the addition of a flocculant. The flocculation process creates so-called flocks, which are easily retained by the filter or settle to the bottom of the pool, from where they need to be vacuumed.
