Abstract
In a method and a system for reducing at least an amount of disinfection by-products in water, the system has a dosing pump (15) for adding a photocatalyst (36) into a stream (17) of the water to obtain a mixed stream (17′), and a photo reactor (20) adapted to receive the mixed stream (17′) and to irradiate the mixed stream (17′) with photons, the photocatalyst (36) in the mixed stream (17′) producing free radicals on being irradiated with the photons, wherein the dosing pump (15) is controllable responsive to an amount of absorption of the photons by the mixed stream (17′).
Claims20
A system for reducing at least an amount of disinfection by-products in water, comprising:
- at least one dosing pump for adding a photocatalyst into a stream of the water to obtain a mixed stream, and
- a photo reactor adapted to receive the mixed stream and to irradiate the mixed stream with photons, the photocatalyst in the mixed stream being adapted to produce free radicals on being irradiated with the photons, wherein the at least one dosing pump is controllable responsive to an amount of absorption of the photons by the mixed stream.
A method of reducing at least an amount of disinfection by-products in water comprising:
- adding a photocatalyst into a stream of water to obtain a mixed stream, and
- irradiating the mixed stream with photons, the photocatalyst in the mixed stream producing free radicals on being irradiated with the photons, and
- controlling the addition of the amount of photocatalyst into the stream responsive to an amount of absorption of the photons by the mixed stream.
A method for reducing at least an amount of disinfection by-products in water, comprising:
- adding a photocatalyst into a stream of water by at least one dosing pump to obtain a mixed stream, and
- receiving the mixed stream by a photo reactor and irradiating the mixed stream with photons, wherein the photocatalyst in the mixed stream is adapted to produce free radicals on being irradiated with the photons, and wherein the at least one dosing pump is controllable responsive to an amount of absorption of the photons by the mixed stream.
