Ozone generation system

Outline

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

The ozone generation system developed by METAWATER realizes high-efficiency ozone generation based on advanced technologies. Based on this technology, we have delivered our products to many supply water and waste water facilities to date.

Features

Effects of oxidation power of ozone

• Deodorization
  Oxidizes and decomposes odor components and dissolved components into odorless and soluble substances.
• Discoloration
  Decomposes coloring components such as pigments and humic substances for discoloration.
• Oxidation
  Also effective for the decomposition of harmful substances and for various types of cleansing.
• Disinfection
  Destroys and inactivates viruses, bacteria and fungi.

Examples of ozone used in the field of water and wastewater treatment

• Supply water
  Supply of tasty tap water (decomposition of odor substances and decomposition of trihalomethane precursor substances).
• Sewage
  Reuse as landscaping water and hydrophilic water (deodorization, discoloration and disinfection of treated wastewater).

Application examples in other fields

Washing and sterilization of foods and beverages, disinfection of devices for manufacturing semiconductor components and liquid crystal displays, disinfection of medical equipment, etc.

Technologies and embodiment

High-efficiency ozone generation tube

When it comes to the efficient generation of ozone by means of silent discharge, the dimensional accuracy of the discharge parts on the electrodes and efficient cooling of the ozone generation tube are important. METAWATER’s ozone generation tube boasts excellent dimensional accuracy and is constructed to offer a high level of cooling effects. Owing to the construction, it achieves high efficiency in the generation of ozone.

Highly reliable system

A highly reliable ozone generation system is delivered through the combination of an ozone generation tube with low risk of breakage and inverter power technology that is highly acclaimed in both the domestic and international markets.

Measure against higher harmonic waves

A PWM converter is made available as an option that makes the power factor of approximately 1 so as to realize a power source that is free from higher harmonics.

Model lineup

METAWATER proposes optimal ozone systems in accordance with the usage conditions of the customer, such as the purpose of the treatment and amount and quality of the water.

Made-from-air type

Features

Since oxygen in the air is used to generate ozone, air becomes raw material for generating ozone only by eliminating the unnecessary moisture contained in the air. This type is widely used as a basic method of ozone generation.

Made-from-oxygen type

Features

Using oxygen gas makes it possible to generate ozone more efficiently (higher in concentration) than with the made-from-air type. This increases the oxidation power (higher reaction efficiency) of ozone. Additionally, the equipment is made smaller in size because the amount of gas necessary for ozone generation is smaller.

We have a wide range of products for both types, from small to large in terms of capacity.
