River Cleaning System

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.

Features

  • Super-fine air bubbles: With a diameter of just 0.4 - 0.9 mm, the very fine bubbles are slow to rise to the surface and their large contact area gives them a high oxygen dissolution efficiency even in shallow water.
  • Reduces foul odors: Because most of the oxygen generated dissolves in the water there is little discharge of air bubbles into the atmosphere, thereby reducing bad odors.
  • Easy maintenance: Except discharge nozzles installed underwater , all the equipment is installed on land, thereby facilitating easy maintenance.
  • Easy operation: Employs an automatic oxygen supply controller to facilitate system operation management.
