Anti-fouling surface, and radiation source assembly and fluid treatment system comprising same

摘要

An element having an immersible portion for contact with an aqueous liquid, the immersible portion having a contact surface for contact with the aqueous liquid, the contact surface configured to have strong acidity, a radiation (e.g., ultraviolet radiation) source assembly, a radiation (e.g., ultraviolet radiation) source module and a fluid (e.g., water) treatment system incorporating this element applicable to any surface in contact with fluid that is susceptible to build-up of fouling materials. The embodiments obviate or mitigates the rate of accumulation of fouling on surfaces in contact with aqueous solution, such as the protective (e.g., quartz) sleeves in an ultraviolet radiation fluid treatment system, by modifying at least a portion of the surface of those sleeves in contact with fluid (e.g., water) to have an inherent strong surface acidity.

主权项

1. An ultraviolet radiation fluid treatment element configured to inhibit fouling materials in the fluid from building up on a contact surface of the element, comprising:
an ultraviolet radiation source; and ultraviolet transparent protective structure adjacent the ultraviolet radiation source and having an immersible portion for contact with the fluid, the immersible portion comprising the contact surface which is configured for contact with the fluid, the contact surface being configured to have immobilized on an outer fluid-contacting surface thereof a solid film having strong Bronsted acidity and configured to inhibit build-up of the fouling material on the contact surface.
