초록 ▼

The invention relates to a water treatment using an UV AOP. The invention combines an UV AOP (11) applied to a water containing a free chlorine species (8) with a chemical post treatment (14), a quenching. The quenching (14) is applied to said water (9) after the UV AOP (11) able to reduce a remaini

대표청구항 ▼

1. A method for treating water comprising: adding a chlorine species to a water to be treated in an amount to provide a dissolved chlorine species having a weight ratio in the water to be treated relative to contaminants of the water to be treated in a range of about 1,000:1 to about 10,000:1;irradiating the water with ultraviolet irradiation to degrade-a first portion of the dissolved chlorine species; andquenching the water to reduce a second portion of the dissolved chlorine species. 2. The method of claim 1, wherein the chlorine species is one of chlorine and chlorine dioxide. 3. The method of claim 1, further comprising measuring a concentration of the dissolved chlorine species at at least one of a time before and after irradiating the water with the ultraviolet irradiation to provide a measured concentration of the dissolved chlorine species. 4. The method of claim 3, further comprising controlling the quenching based on the measured concentration of the dissolved chlorine species. 5. The method of claim 1, wherein quenching comprises adding a quenching agent to the water. 6. The method of claim 1, wherein the water to be treated comprises 2 μg/l or less of water contaminants. 7. The method of claim 1 wherein the weight ratio of the dissolved chlorine species in the water to be treated and contaminants of the water to be treated is in a range of about 3,000:1 to about 8,000:1. 8. The method of claim 7, wherein the weight ratio of the dissolved chlorine species in the water to be treated and contaminants of the water to be treated is about 6,000:1. 9. The method of claim 1, wherein irradiating comprises irradiating at a wavelength of about 100 nm to 400 nm. 10. The method of claim 1, wherein irradiating comprises irradiating at a dose of about 400 J/m2 to 4000 J/m2. 11. The method of claim 1, wherein the water to be treated is from a source of one of municipal water, potable water, waste water, industrial water, process water and ultrapure water. 12. The method of claim 3 wherein measuring a concentration of the dissolved chlorine species comprises measuring a concentration of the second portion of the dissolved chlorine species. 13. The method of claim 5 wherein quenching comprises reacting the quenching agent with the second portion of the dissolved chlorine species. 14. The method of claim 5 wherein quenching comprises adsorbing of the second portion of the dissolved chlorine species by the quenching agent. 15. The method of claim 5 wherein quenching comprises forming ions and water. 16. The method of claim 5 wherein the quenching agent comprises one of hydrogen peroxide, thiosulphate, thiosulphate salts and activated carbon.
