Acidification pre-treatment for UV water disinfection

摘要

A pre-treatment method injecting sulfur dioxide into waters containing suspended solids to undergo ultra violet disinfection to form sulfurous acid (H2SO3) to self-agglomerate and precipitate solids from the wastewater for settling or filtration removal and provide acid to reduce bicarbonate and mineral scaling and microbial buildup on ultraviolet light tubes to improve their performance.
