Ozone System

Ozone technique is an advanced water quality treatment technique, and is effective in water treatment such as the removal of foul odor from tap water in filtration plants, improvement of water taste, removal of harmful substances in the process of sewerage/wastewater treatment facilities, and sterilization of water recycling.

MOLIT maximizes ozone treatment efficiency through the hybrid technology of microbubble creation/cyclone, which is a self-developed technology, and uses the technology in water treatment in various fields.

Ozone Generator

Difference from other products

High frequency control technology

  • Retaining a variety of models from 10g/h to 170kg/h based on ozone production amount
  • Oxygen-feed method, using oxygen generator, Air-feed method can be selected
  • Due to skin effect where current is concentrated on the surface of dielectric discharge tube, ozone generation efficiency is maximized as discharging gap is narrower.

High frequency control technology

  • High frequency control technology
  • Retains the world’s best high frequency technology
  • Increase of current supply and valid discharge section
Ozone production increases by 30% or more compared to other companies (intermediate frequency)

Ultra-fine interval dielectric discharge tube technology

  • Ultra-fine discharge interval
  • Increase in ozone production
  • Increase in numbers of discharge tubes
Increase in Ozone production
