Depuration
Definition:

(20) Throughout the process, depuration water contained high concentrations of V. vulnificus, indicating that the disinfection properties of UV radiation and 0.2-microns-pore-size filtration were less than the rate at which V. vulnificus was released into seawater.
Purification
Definition:
(n.) The act of purifying; the act or operation of separating and removing from anything that which is impure or noxious, or heterogeneous or foreign to it; as, the purification of liquors, or of metals.
(n.) The act or operation of cleansing ceremonially, by removing any pollution or defilement.
(n.) A cleansing from guilt or the pollution of sin; the extinction of sinful desires, appetites, and inclinations.
Example Sentences:
