Project Name: Suzhou New District Xinning Water Supply Development Co., Ltd Project

 

Project Profile:
  Established in June 1994, Suzhou New District Xinning Water Supply Development Co., Ltd. is the only professional company within High-tech Area which integrates water production, water supply and the construction of water supply network as one group. The company has six administrative departments and two water plants (Xinning water plant, the second water plant in high-tech zones). The scale of existing water production is 300,000 m3/day and the water supply services covers 258 km2 of high-tech zone. The designed water supply capacity of the No. 1 and No.2 water plants of Suzhou New District Water Company are 150,000 m3/d and 300,000 m3/d. It is approved and agreed to carry out technological transformation on the basis of the conventional water purification process and add the pre-ozone and ozone / biological activated carbon processes. Therefore, the No.1 and No.2 water plants need to add the additional equipment and related materials (components) for ozone systems. According to the requirements technological process, ozonation can be divided into pre-ozonation (before) and post ozonation (main) two parts.

Project Scale: No. 1 water plant is 150,000 m3/d and No. 2 water plant is 300,000 m3/d

 

Overview of Ozone System:

 

1. No.1 water plant: The maximum processing capacity of pre-ozonation: 154,500 m3 / d, 6438m3 / h. Set a pre-ozone contact tank. The ozone is added into the pre-ozone contact tank. The designed dosage for pre-ozone:0.5-1 .0 mg / L.
2. No.2 water plant: The maximum processing capacity of pre-ozonation: 309,000 m3 / d. Set two pre-ozone contact tanks which can work independently and the maximum processing capacity of each tank is 6438 m3/h. The ozone is added into the pre-ozone contact tank. The designed dosage for pre-ozone:0.5-1 .0 mg / L.
