puhditus

Puhditus is a Finnish noun that denotes the act or process of purification or cleaning. It is derived from the same root as the verb puhdittaa/puhdistaa, which means to purify or clean. In contemporary Finnish, puhdistus and puhdistus are far more common, while puhditus is relatively rare and tends to appear in older, regional, or specialized texts. The sense of puhditus is broad: it refers to removing contaminants, impurities, or unwanted components from a substance, a stream, or a system, and it can apply to industrial, environmental, and hygienic contexts.

In practice, puhditus is most often encountered in discussions of purification steps within manufacturing, water or wastewater treatment, and environmental remediation. In many cases, modern writing would replace it with puhdistus or puhdistus, but puhditus remains a recognized historical or variant form. As a concept, it is closely related to purification, refinement, and cleaning, and is synonymous in some contexts with processes such as filtration, distillation, or chemical purification.

Related terms include puhdistus (the more common noun for purification or cleaning), puhdittaa (to purify/clean), and puhditus is viewed as a less common variant. The term sits within the broader domain of purification and cleansing in scientific, industrial, and environmental discourse.
