Ozone disinfection technology for swimming pool water treatment

Ozone disinfection technology for swimming pool water treatment

Because of the strong oxidation effect of ozone, it can decompose organics at a reaction rate 100 times higher than chlorine, which can effectively prevent chlorine from combining with urea to form chloramine. At the same time, it can oxidize the precursor of THM, thus greatly reducing THM. Hydroxyl formed in water after ozone decomposition can hydrolyze multivalent metal ions into colloidal compounds, which can be filtered out through sand filters, not only improving the sense of water, but also removing the organics decomposed by oxidation in water.

Compared with the chlorine disinfection method, the water quality and venue environment have been significantly improved after ozone technology was used for the water treatment of swimming pools:

(1) Ozone and its secondary products (such as hydroxyl) have the strongest bactericidal and virus inactivating effects, which can effectively prevent the spread of infectious diseases. The experiment proved that the effect of ozone with the same concentration on killing bacteria and viruses is 600-3000 times that of chlorine. When the ozone concentration is 1mg/L, it only takes 5 seconds to inactivate fecal Escherichia coli, and it takes 15000 seconds to use chlorine with the same concentration.

(2) It is an internationally recognized environment-friendly green bactericide and will not cause any secondary pollution to the environment.

(3) When chlorine agent is used for disinfection, chlorinated organic compounds and chlorine and other toxic gases evaporated from the water are gathered above the swimming pool and are not easy to disperse, damaging people's respiratory organs and seriously affecting people's health, while ozone will not cause such problems at all.

(4) Ozone can effectively decompose humus in water, oxidize iron and manganese ions in water, and decompose small organisms scattering light in water, thus greatly improving the clarity of water and making it beautiful blue, while chlorine preparation has no such effect. In order to make the water blue, the swimming pool using chlorine preparation often needs to add copper sulfate, which is extremely harmful to people.

(5) After chlorine preparation is added, it will inevitably lead to the change of pH value of water, making people feel uncomfortable, so alkaline or acidic substances need to be added for neutralization. Ozone is a neutral substance, which will not cause such problems.

(6) The use of ozone generator can greatly reduce the management and operation difficulty of water treatment process, and has high safety. Chlorine preparation is dangerous in transportation, storage and use.

(7) Ozone can decompose organic matters in water and has micro flocculation effect, so under normal passenger flow, flocculant can not be used.

(8) Under certain conditions of use, it is unnecessary to add chlorine disinfectant, flocculant and pH regulator, and ozone can be used as the only treatment agent
