MABR membrane market projected to reach $46.74 million by 2032

The global Membrane Aerated Biofilm Reactor (MABR) membrane market is projected to grow steadily, with a compound annual growth rate (CAGR) of approximately 5.7% from 2026 to 2032. According to research by LP Information Co., Ltd., the market size is expected to reach approximately $31.09 million in 2025 and climb to $46.74 million by 2032.

MABR technology utilizes hydrophobic polymer membranes to facilitate gas transfer and biofilm attachment. This method improves oxygen transfer efficiency and reduces aeration energy consumption compared to traditional bubble aeration, making it suitable for upgrading public sewage treatment plants and decentralized wastewater projects.

The market is characterized by high concentration, with the top five companies holding a market share of approximately 86%. Leading players include Fluence Corporation, Hydroking Tech, Veolia, and DuPont OxyMem. The competitive landscape is shifting from simple product supply toward integrated solutions involving oxygen transfer efficiency, module structure, and long-term operational reliability.
