Before choosing a perhydrol for pools, let's remember the school chemistry curriculum. Hydrogen peroxide (or H2O2, or perhydrol) is one of the simplest representatives of peroxides. The solution is liquid, colorless, soluble in alcohols, ethers, water. Explosive in concentrate. It is itself a solvent. In water, after a few hours, it decomposes into O2 and H2O. Pure peroxide is more stable. The qualities of a bactericidal agent are due to the tendency to redox reactions.
Many people familiar with chemistry doubt that pool perhydrol is generally effective. How are things really? Should I use it to disinfect the water in your pool? Let's try to figure it out.
Not every manufacturer will recommend using their perhydrol for swimming pools. He is really capable of disinfecting, but this action is comparable, perhaps, with an explosion. In other words, if there are a lot of bacteria and they need to be destroyed as soon as possible, then pool perhydrol is just perfect. It kills microbes, is relatively cheap, and breaks down quickly. But onagainst the backdrop of these advantages, there are also serious disadvantages.
Firstly, the action of the solution is short-lived, so disinfection will have to be carried out regularly and often.
Secondly, by adding perhydrol to the pool, you will have to wait twelve hours (minimum decay time) before bathing - undecomposed hydrogen peroxide is quite aggressive towards organics (dries the skin, leaves burns at higher concentrations).
Thirdly, disinfection will require at least 50 g/m3. With a lower concentration of burns, of course, there will be no, but there will be no benefit either. Is there a way out? It turns out that there is - perhydrol-37 for the pool (37%). The approximate consumption per 1000 liters of water is 1.5 liters of perhydrol. There is a solution with a stronger concentration - 50%, which is better to use in large pools. Re-treatment should be carried out when the water becomes cloudy.
This treatment is not suitable for public pools, since, as already mentioned, the duration of action is quite short due to the rapid decomposition and recombination of O2. But for home consumption, perhydrol, for some reasons, is better suited than, for example, chlorine. It leaves no residue, is odorless and, despite the short duration of action, with the correct calculation of the dosage, it does an excellent job as a disinfectant.
Oxygen compounds can be in the form of tablets or granules. When they hit the water, they immediately begin to react. The reaction rate is increasedcatalysts, the pH decreases.
The combination of perhydrol with other agents (for example, silver) can increase the effect of disinfection. For dosing, it is better to use automatic dispensers. These can be both the simplest devices and the latest design, fully automated, controlling the concentration and independently making the necessary measurements.
