Do you often go to the swimming pool and find that the water in the swimming pool is sparkling and crystal clear? The clearness of this pool water is related to the residual chlorine, pH, cyanuric acid, ORP, turbidity, and other factors of the pool water quality.
Cyanuric acid is a disinfection by-product of the disinfectants dichloroisocyanuric acid and trichloroisocyanuric acid, which can stabilize the concentration of hypochlorous acid in water, thus producing a long-lasting Disinfection effect.
However, because Cyanuric Acid is not easy to decompose and remove, it is easy to accumulate in water. When the concentration of cyanuric acid increases to a certain level, it will seriously inhibit the disinfection effect of hypochlorous acid and increase the number of bacteria. At this time, the residual chlorine we detect will be low or even undetectable. This is what we usually call the “chlorine lock” phenomenon. If the cyanuric acid is too high, the disinfection effect is not good, and the pool water is easy to turn white and green. At this time, many people will add more trichlor, which will lead to higher cyanuric acid in the water, forming a vicious circle, and the pool water will become “a pool of stagnant water” from then on! This is why swimming pool managers should be equipped with a water quality detector, because more detection of cyanuric acid in the swimming pool can prevent excessive cyanuric acid in the pool water.
Treatment method for high Cyanuric Acid: Stop using disinfectants containing Cyanuric Acid (such as trichloro, dichloro) and switch to disinfectants without cyanuric acid (such as sodium hypochlorite, calcium hypochlorite), and insist on daily Add some new water, so that the cyanuric acid will slowly drop down.
Of course, Cyanuric Acid is too low and unstable, and the sun will quickly decompose hypochlorous acid, which will also cause poor Disinfection effect, so the cyanuric acid in the swimming pool should be maintained reasonably. The GB37488-2019 standard clearly stipulates that the cyanuric acid in the swimming pool should be maintained at ≤50mg/ The range of L is qualified, because within this range, it will not have an irritating effect on the skin, and at the same time it can maintain the disinfection effect for a longer period of time. The water quality of the swimming pool is also crystal clear for a long time. Only by standing by the pool can you see the various shapes of the bottom of the pool, so you can swim with confidence!
