GE Supplies Wastewater Treatment Equipment to China’s Largest Membrane Bioreactor Plant

GE ZeeWeed membraneTreating wastewater is essential for environmental compliance with discharge regulations. It can also save money and freshwater when the water is purified to meet reuse standards.

General Electric says its water and process technologies help customers achieve both. GE will supply its wastewater treatment equipment for an upgrade of the Luo Fang Wastewater Treatment Plant in Shenzhen City, Guang Dong province, making it the largest membrane bioreactor (MBR) plant in China.

The Luo Fang facility is responsible for treating municipal wastewater for the city of Shenzhen and once the upgrade is complete, will process 400 million liters of wastewater per day.

The upgrade will enable the Luo Fang Wastewater Treatment Plant to meet new effluent standards while staying within the existing footprint of the facility. Using GE’s ZeeWeed 500D membranes (pictured), the plant will increase its capacity by 150 million liters per day and will be able to reuse water.

In other water treatment news, a team of scientists working with BASF say they have developed a new type of membrane for purifying industrial water that is robust and easier to clean and recycle, compared to traditional polymeric membranes.

As Phys.org reports, a supramolecular aqua material can be utilized as a sustainable membrane for water purification at high pressures. This hybrid membrane combines the toughness of polymeric membranes with the sustainability benefits of supramolecular systems.

The BASF team along with rhe Rybtchinski group from the Weizmann Institute of Science, Israel, found “the hybrid membrane sustained high pressures and could also be easily disassembled for cleaning and recycling. These favorable properties induced through synergistic self-assembly make such aqua materials good candidates for demanding large-scale industrial applications.”
