As stated in an article published by the EPA in December 2025, the National Secondary Drinking Water Regulations (NSDWRs) have enforced suitable guidelines for regulating contaminants, particularly for exceeding the fluoride secondary standard of .0 mg/L. Besides, community-based water systems surpassed the fluoride secondary standard of 2 mg/L, and not exceed the primary standard of 4.0 mg/L for fluoride. Therefore, with all these limitations, the market is gaining increased exposure.
- MBR integration with anaerobic digestion for energy-based treatment: This driver is positively coupling the membrane bioreactor market with anaerobic digestion to gain energy-based wastewater treatment. As per an article published by the Journal of Environmental Management in December 2023, the global municipal solid waste (MSW) has been readily increased with population expansion and is projected to reach 3 billion tons by the end of 2050. In addition, the per capita MSW generation rates tend to vary significantly between nations with distinctive levels of economic development, ranging from 0.11 to 4.54 kg·day−1. Besides, high-income nations presently produce the largest quantity of MSW, accounting for 300 to 500 Mt y−1, in comparison to 130 to 330 Mt y−1 for middle and low-income nations, thus driving the market growth.
Challenges
- Increased manufacturing cost of advanced membrane materials: The production of high-performance MBR membranes relies on specialized polymers, precision casting processes, and quality-controlled pore formation techniques, all of which contribute to elevated manufacturing costs. Besides, PVDF membranes require complex phase inversion processes under tightly controlled temperature and humidity conditions, while ceramic membranes demand high-temperature sintering of aluminum oxide or silicon carbide powders, driving up energy and equipment expenses. Additionally, the raw materials themselves, especially high-purity polymers and specialty ceramic precursors, carry significant price volatility linked to petrochemical and mining supply chains, which is negatively impacting the membrane bioreactor market.
- Chemical incompatibility and disposal of spent chemicals: Systems in the membrane bioreactor market require regular chemical cleaning protocols to recover permeability and control biofouling, typically using sodium hypochlorite, citric acid, oxalic acid, or caustic soda. However, from an advanced materials standpoint, repeated chemical exposure accelerates membrane polymer aging, leading to brittleness, loss of mechanical integrity, and irreversible permeability decline. Many polymeric membranes exhibit poor resistance to high concentrations of oxidizing agents or extreme pH conditions, forcing operators to use milder cleaning cycles that are less effective. Additionally, the spent chemical solutions generated during cleaning contain concentrated organic debris, inorganic scale fragments, and biocides, classifying them as hazardous industrial waste.
