AIR-MIST

Air-Mist® System

Pure oxygen-dissolved water to improve odor and water quality in lentic systems.

Technology Description

  • High purity oxygen, selectively separated from air, is converted to micro-nano-bubbles and injected to and diffused in rivers, lakes and reservoirs.
  • Effective for improving water quality, reducing disagreeable odor, and suppressing anaerobic status of bottom water.

System Composition

  • Pure Oxygen Generator + Oxygen Dissolver
    High-purity oxygen generator : oxygen with purity over 90% is extracted with PSA (Pressure Swing Adsorption) (No separate oxygen tank required)
    High-efficiency Oxygen Dissolver : Dissolves high-purity oxygen in water up to concentrations of 40% New Excellent Technology No.51-030 (Ministry of Agriculture, Food and Rural Affairs)
  • Micro-nano-bubble Generator
    Non-clogging Venturi-type nozzle generates micro-nanobubbles with vortex technology.
    Micro-nano-bubbles smaller than 30㎛ are generated and dissipated where the surface rising speed is extremely slow for effective increase in dissolved oxygen level.

Configuration

With its slow surfacing speed, micro-nano-bubbles do not exhaust to the air and remain in the water for a significant amount of time, maximizing the DO concentration increase effect.

Applications

  • Pig Manure Treatment Device
    Oxygen is dissolved with high efficiency with no clogging of extremely viscous slurry.
  • Pure Oxygen Aerator for Waste Water Treatment Plant
    Adopted to supplement dissolved oxygen in waste water treatment plants. Features a structure that is not blocked by debris such as hair.
  • Improving Water Quality in Lentic Systems (DO supply)
    Circulate water of and supply oxygen to lakes and reservoirs
    Prevent anaerobic decomposition of sedimented sludge
    Prevent green and/or red algae
  • Supply Dissolved Oxygen to Fish Farms
    Supplies dissolved oxygen at high efficiency, remarkably reducing oxygen procurement costs.
  • Pure Oxygen Supply Device for Relay Pumping Operations
    Applied as pure oxygen dissolving device to improve anaerobic odor treatment in relay pumping facilities. Dissolves high purity oxygen while allowing fluent passage of debris, favorable in resolving public complaints.
  • Other Applications
    Applicable to dissolve ozone and nitrogen.
    Selectively applicable to dissolve specific fluids (liquids and gas)

Anticipated Effects

  • Improved Water Quality
    Water circulation in reservoir
    Increased level of dissolved oxygen
    Preventing anaerobic development in bottom water지
    Green algae control
    Other water quality improvements for lentic systems
  • Odor Management
    Sewage disposal tanks
    Livestock manure treatment plants
    Waste water treatment plants / Sewage treatment plants
    Rivers / Reservoirs / Ponds
  • Ecological Restoration
    Preventing carnage of fish (prevents exhaustion of dissolved oxygen)
    Stimulates development of aquatic animals and plants
