09 September 2022 | This year in July the Yindingzhuang Wastewater Treatment Plant employs hollow fiber ultrafiltration membrane modules from the company Toray. This advanced facility in Baoding, Hebei Province, is one of the largest in China using such modules, with a daily treatment capacity of 315,000 cubic meters.
Beijing-based Toray Bluestar Membrane Co., Ltd., is supplying and providing technical services for these modules at the facility. They will help China enhance its aquatic environment and resolve water shortages by offering products and technical support through that subsidiary.
Construction as part of a public project
China built the new facility as part of a key public project to safeguard the ecology of Baiyangdian, a freshwater lake near Xiong’an New Area, a fast-expanding development hub. Furthermore China is raising its waste water treatment standards in keeping with increasingly strict environmental regulations. Switching to an advanced process employing ultrafiltration membrane modules became imperative in view of a common activated sludge process failing to match the government’s latest water quality standards.
The membrane modules employ polyvinylidene fluoride, a non-reactive thermoplastic fluoropolymer with outstanding high chemical and physical stability. The company applied a proprietary manufacturing technique to create a composite membrane structure that ensures high water permeability and minimal fouling. With a membrane module pore size of 0.01 microns it is smaller than those of rival offerings, significantly enhancing the quality of filtered water. China chose these modules for this public project on the strength of their reliability, lower running costs from less frequent chemical scrubbing, and results that surpass water quality standards.
Profile of the new facility:
• Location: Baoding, Hebei Province, China
• Treatment capacity: 315,000 cubic meters daily
• Operational start: July 8, 2022
• Plant Design : North China Municipal Engineering Design & Research Institute Co., Ltd
