Dübendorf, Switzerland, Dec. 9, 2010 -- Ozonia China signed a new ozone contract with Beijing Drainage Group, the biggest wastewater company in China in terms of total assets (these amount to $2.9 billion) to reinforce the Bei Xiaohe Waste Water Treatment Plant.
Beijing Drainage Group selected the Ozonia ozonator CFV-05 as the most efficient and cost effective solution of three invited bidders (Ozonia, ITT Wedeco and Mitsubishi).
The 1st phase of the Bei Xiaohe Waste Water Treatment Plant ( WWTP) was built in the 1980's with a capacity of 40 ML/d in order to cater for the Beijing Asia Games.
The 2nd phase, with a capacity of 60 ML/d, was built in the 2000's.
In 2008, reclaimed water from the plant was utilized in the National Stadium and the Olympic lake during Beijing Olympic Games.
Since its creation, urbanization has increased the demand on the plant and created the need to significantly upgrade the existing facility. The ozone treatment is aiming at the reclamation of secondary effluent which contains abundant organic substances and bacteria.
Beijing is leading China's drive to become the world's biggest user of recycled wastewater. The Bei Xiaohe WWTP project is part of an overall upgrade of the 8 WWTP of Beijing and Ozonia China has already been selected to provide ozone disinfection system to 3 of those: Qinghe WWTP, Jiuxianqiao WWTP and Bei Xiaohe WWTP.
Prospect of a ''green'' chemical environment with ozone
Ozone emerges as a very versatile solution offering the highest efficiency in the treatment of effluents. It allows the production of an effluent with no micro-organisms, no color, no odor, low COD level and suitable for discharge into the environment, use in agriculture or return to the process. Moreover, there is a true destruction and not a displacement of the pollution.
Unlike systems that only displace pollution by producing large amounts of sludge or by producing a concentrate of this pollution, ozone really eliminates the pollution and produces only a small amount of biological sludge.
With these benefits, ozone has a considerable potential as the "green" chemical for all applications involving an oxidation process.
OZAT® CFV range, Ozonia's latest generators for medium-sized ozone applications. An innovative, cost efficient and environmentally friendly ozone generation process.
The OZAT® CFV ozone generators incorporate Ozonia's patented "Advanced Technology" dielectric segments together with a state-of-the-art IGBT power supply unit.
The design is based on feedback from hundreds of operators and includes the latest technology to ensure continuous operation at full-load in industrial environments. A feature of the larger units is the fused dielectric tubes which makes them particularly suitable for remote service in drinking water plants. An OZAT® CFV unit is integrated from the ozone generator, the power supply for the high voltage medium frequency supply to the generator, PLC control, process related control equipment and skid interconnections. The PLC system and optional bus ensures flexible operation and allows integration into all types of plant concepts.
How does it work?
Ozone, the triatomic form of oxygen, is generated by recombining oxygen atoms with oxygen molecules. This process takes place in the gap between the dielectric layer on the high voltage electrode and an earth electrode in the ozone generator vessel. When high voltage is applied to this arrangement a silent electrical discharge occurs in the gap which excites the oxygen molecules in the feed gas, usually air or oxygen, flowing through the gap which causes them to split and combine with other oxygen molecules to form ozone.
