Ozone generation system

Outline

The ozone layer, located 20 to 50 km above the ground surface, protects our world from intense UV rays. An eco-friendly approach using the oxidation power of ozone, a substance widely seen in nature, has been used for many years to support our daily lives in the field of water and air treatments.

The ozone generation system developed by METAWATER realizes high-efficiency ozone generation based on advanced technology. This technology has been adopted in many water and waste water facilities to date.

Features

Effect achieved by oxidation power of ozone

• Deodorizing
  Oxidation and decomposition of odor components and dissolved components into odorless and soluble substances.
• Bleaching
  Coloring components, such as pigments and humic substances, are decomposed and bleached.
• Oxidation
  Also effective for the decomposition of harmful substances and for various types of cleansing.
• Disinfection
  Virus, bacteria and fungi are disinfected and made inert.

Application examples of ozone in the area of water and wastewater treatments

• Supply water
  Supply of good tap water (decomposition of odorous substances and decomposition of trihalomethane precursors).
• Sewage
  Reuse as landscaping water and hydrophilic water (deodorizing, discoloring and disinfection of treated wastewater).

Examples of applications in other fields

Disinfection and cleansing for foods and beverages, semiconductor and LC manufacturing, the sterilization of medical devices, and so on.

Technologies and performances

High-efficiency ozone generation tube

To efficiently perform ozone generation by means of silent discharge, the dimensional accuracy of a discharge section on an electrode and efficient cooling of the ozone generation tube are both important. The ozone generation tube developed by METAWATER has achieved excellent dimensional accuracy and offers high cooling efficiency. High-efficiency ozone generation is possible thanks to this structure.

Highly reliable system

A highly reliable ozone generation system is supplied based on a combination of an ozone generation tube characterized by low breakage risks with inverter power technology that is highly acclaimed in the domestic and international markets.

Measure against higher harmonic waves

A power source preventing higher harmonic waves is achieved by the optional adoption of a PWM converter that can generate a power factor of approximately 1.

Model lineup

METAWATER proposes the optimum ozone system for each customer depending on individual application conditions, such as purpose of treatment, water capacity and water quality.

Air material approach

Features

With this method, oxygen in the air is used to generate ozone. Therefore, the material for the ozone can be obtained only by eliminating the unnecessary moisture in the air. This air material approach has been widely used as a basic ozone generation method.

Oxygen material approach

Features

Using oxygen gas means that it is possible to generate ozone more efficiently (high-concentration ozone) than with the air material approach, thus making it possible to obtain ozone with a greater oxidation power (high reaction efficiency). Additionally, smaller equipment can also be used because the gas capacity necessary for ozone generation is lower.

We have a wide range of products for both approaches, from small-capacity to high-capacity types.
