New Ozone Wastewater Contract with the Beijing Drainage Group

Ozonia China has 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 from three invited bidders.

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.

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.

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.
