We have signed a contract with Atal Engineering Ltd. in Hong Kong for delivery of Filtralite filter media to the Weihai Manshan Water Treatment Plant in the Shandong province in China.

The ordered volume is 600 m3 and the delivery will take place during first quarter of 2010.

The production capacity of the plant is 100.000 m3/day for this first stage. The capacity will be doubled in the second phase.

Filtralite filter material was selected due to its superior technical characteristics compared to traditional filter materials where the internal and external porosity gives a better storage capacity as well as slower pressure build up in the filter. This result in longer filter runs, the filtration velocity can be increased and backwash water will be reduced and production of water increases.

The raw water to the Weihai Manshan Water Treatment Plant comes from a reservoir.
 
The main purification process is static mixing followed by Grid Box horizontal flow sedimentation. Then follows the filter stage with the Filtralite filter material. The filter area is 600 m2 and the depth of the filter material is 1 meter. The plant has a centrifugal sludge dewatering system.

The start up of the plant will be in June 2010.

This is the first time Atal Engineering orders Filtralite filter media for a Water Treatment Plant in mainland China.

Filtralite filter material has been installed in more than 100 BAF’s (Biological Aerated Filters) for wastewater treatment around the world. Earlier deliveries in China with Filtralite media are to wastewater plants in Dalian, Quiyang, Karamay, Wulumuqi and Xiamen and to Tai Po Drinking Water Plant in Hong Kong.
