PROBEST: Zhao’an West Sewage Treatment Plant (Phase I) and Supporting Pipeline Network Project

Project Overview

West Sewage Treatment Plant is located in Zhao’an County, Zhangzhou City, Fujian Province, serving as a key component of the county’s comprehensive pollution control system. The Phase I project and supporting sewage pipeline network involve a total investment of 200 million RMB, with a daily sewage treatment capacity of 12,000 tons. The effluent quality meets the national Grade 1A discharge standard. The construction of this project is crucial to establishing a three-dimensional pollution control supervision system, enhancing ecological protection capacity and project carrying capacity of the industrial park.

Project Construction & PROBEST Solutions

In December 2020, PROBEST won the bid for the Zhao’an West Sewage Treatment Plant (Phase I) and Supporting Pipeline Network Engineering Service Project. We deployed a full range of PROBEST online automatic water quality monitoring analyzers, including COD, ammonia nitrogen, total phosphorus (TP), total nitrogen (TN) and other key parameter monitors, to achieve precise and efficient real-time online monitoring of sewage quality.

The application of PROBEST intelligent monitoring equipment has effectively improved environmental quality and daily monitoring efficiency of the sewage treatment plant. All PROBEST intelligent monitoring devices have been fully delivered and put into stable operation.
