River Cleaning System

General Description

In this simple cleaning system, oxygen-deficient water from rivers and other waterways with low dissolved oxygen (DO) levels is taken in , and treated by dissolving the oxygen (95% purity) generated by a pressure swing adsorption (PSA) type oxygen generator under pressure until it reaches a supersaturated level, and then it is discharged from nozzles back into the waterway.

In DO-deficient water environments, discharging water containing high concentrations of dissolved oxygen and super-fine air bubbles creates a current in the water and makes it possible to deliver the enriched oxygen over a wide area.
