Toshiba's Ozone Technology provides
Ozone is a powerful oxidant, stronger than chlorine. It is used to disinfect, deodorize, decolorize and decompose organic matter in water. Toshiba's TGOGS™ ozone generator ensures safety, reliability and durability with high efficiency and low power consumption.
(*1) THMs: Trihalomethanes
A large amount of ozone is generated efficiently by silent discharge.
The silent discharge continually occurs without spark when a high AC voltage is applied between the two electrodes placed parallel to each other through dielectric material.
When dry air or oxygen flows between the electrodes, oxygen atoms (O) are ionized, and ozone (O3) is formed in recombination of ionized oxygen atoms (O) and unionized oxygen molecules (O2).
The ozone treatment process varies according to the purpose of treatment. Ozone injection points are determined by the expected effect or substance to be treated.
(*2) COD: Chemical Oxygen Demand
(*3) O&M: Operation and Maintenance
(*4) PSU: Power Supply Unit
We, Toshiba, provide flexible system configuration to meet the particular treatment requirements and capacities of our clients.
Ingredient gas suppliers, cooling systems, waste ozone decomposition systems and reaction tanks are configured according to the inflow water quality, treatment capacity and location of installation.
We ensure reliability, economic efficiency and maintainability to offer ozone treatment systems by taking into account different circumstances.
We offer a system layout suitable for your needs by taking into account electrical equipment; ingredient gas piping, cooling water and gases containing ozone; ease of operation and maintenance; safety of the work environment; and efficient use of installation space.
