RO Membrane Chemicals Market Trends




  • Intense Demand for High-Quality Water among Industries to Foster Growth.




High-quality water is of utmost significance among several industries, which has raised the demand for high-grade RO membrane chemicals over the years. Reverse osmosis membranes are witnessing huge demand for producing pure water for multiple applications since these systems facilitate the removal of small as well as large colloids, ions, bacteria, pyrogens, and organic substances from the feed water. The escalating use of RO membrane systems is ultimately leading to higher demand for RO membrane chemicals, as the latter helps get rid of several impurities that are present at the surface of the system during the operation. These chemicals ensure high membrane performance and are, therefore, enjoying robust demand across several end-use industries.


The demand for high-quality water devoid of harmful microorganisms and bacteria has been mounting in the pharmaceutical sector, especially for applications like equipment cleaning, rinsing, and manufacturing of active pharmaceutical ingredients (APIs), drugs, laboratory waters, and non-compendial waters. The expanding application scope of RO membrane chemicals in the pharmaceutical sector and more will most likely translate into considerable revenue generation in the following years.  


Additionally, The Middle East and Africa will offer attractive opportunities to leading vendors in the years ahead, given the heightened demand for water given the exploding population as well as agricultural activities. The RO membrane chemicals market is also presented with opportunities by the expanding desalination industry in the region.

By September 2023, LG Chem aims to increase its business presence through a strategic expansion effort that will see it improve the Cheongju plant’s capacity – a key facility for manufacturing reverse osmosis membranes. The company said it will inject around $95 million (KRW 124.6 billion) by July 2025 to expand the Cheongju site and install a new plant capable of producing up to 400,000 reverse osmosis membranes per year. This growth project is expected to help desalinate an estimated 1.57 billion tons (4.32 million tons per day) of water annually. With this much-purified water available, about 16 million people could benefit from it, which makes up roughly one-third of the Korean population.
