Before choosing a perhydrol for pools, let's recall the school curriculum in chemistry. 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. Itself is a solvent. In water, after several hours, it decomposes into O2 and H2O. Pure peroxide is more stable. The quality of the bactericidal agent is due to the tendency to redox reactions.
Many people familiar with chemistry doubt that perhydrol for swimming pools is generally effective. How are things really? Is it worth it to disinfect water in your pool? Let's try to figure it out.
Not every manufacturer will recommend the use of his perhydrol for swimming pools. He really is able to disinfect, 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 the perhydrol for pools is just perfect. It kills germs, is relatively cheap, and quickly breaks up. But against the background of these advantages, there are serious disadvantages.
Firstly, the action of the solution is short, so disinfection will have to be carried out regularly and often.
Secondly, adding perhydrol to the pool, you will have to wait twelve hours (minimum decay time) before bathing - undecomposed hydrogen peroxide is quite aggressive towards organic matter (it 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 not be, but also benefits. Is there a way out? It turns out there is - perhydrol-37 for the pool (37%). Approximate consumption per 1000 liters of water is 1.5 liters of perhydrol. There is a solution with a higher concentration - 50%, which is better to use in large pools. Re-treatment should be carried out with turbidity of the water.
Such treatment is not suitable for public pools, since, as already mentioned, the duration of action is very short due to the rapid decomposition and reconnection of O2. But for home consumption perhydrol for some reasons is better than, for example, chlorine. It leaves no residue, odorless and, despite the short duration of the action, with the correct calculation of the dosage copes with the work of the disinfector.
Oxygen compounds can be in the form of tablets or granules. When released into water, they begin to react immediately. The reaction rate is increased by catalysts, while the pH decreases.
Combining perhydrol with other agents (for example, silver) can increase the effect of disinfection. It is better to use automatic dispensers for dosing . It can be either the simplest devices or the latest model, fully automated, controlling the concentration and independently making the necessary measurements.
