The Yindingzhuang Wastewater Treatment Plant in China has come online this month and, according to Toray Industries Inc., is using the company’s hollow fiber ultrafiltration membrane module.
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 (83.2 million gallons).
Beijing-based Toray Bluestar Membrane Co. is supplying and providing technical services for these modules at the facility. Toray will help China enhance its aquatic environment and resolve water shortages by offering products and technical support through that subsidiary.
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.
China is raising its wastewater 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.
Toray’s membrane modules employ polyvinylidene fluoride, a non-reactive thermoplastic fluoropolymer with 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.
The Chinese government’s 14th Five-Year Plan for Circular Economy Development has fueled demand for membrane modules to help combat water pollution.
