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.
The RO Membrane Chemicals Market segmentation, based on Type, includes Biocides, Acid Membrane Cleaners, and Alkaline Membrane Cleaners. Acid membrane cleaners, biocides, and alkaline membrane cleaners are the top RO membrane chemical types considered in the report. At present, the biocides segment controls the highest share of the market, and in 2017; it reached USD 600 Mn. It has maintained an impressive growth rate since then and should continue to do so during the review period. Biocides are important RO membrane chemicals that will continue to enjoy solid demand in the coming years. The alkaline membrane cleaner segment could surpass USD 400 Mn by 2025.
Based on Application, the RO Membrane Chemicals Market segmentation includes Membrane Fouling, Membrane Cleaning, and Membrane Scale Control. The membrane fouling category is in the lead and can even cross USD 1,100 Mn by 2025 while procuring an above-average growth rate. Membrane fouling is one of the most common complaints among consumers using RO membranes, which fosters the need for RO membrane chemicals.

By region, the study provides market insights into North America, Europe, Asia-Pacific, and the Rest of the World. APAC controls more than one-third of the total share of the global market. In 2017, APAC had touched over 700 Mn and has been spearheading the global market ever since. India and China are extremely populated nations, not only in the region but across the world, a factor that has been crucial to the market’s strong growth prospects. Both these countries are increasingly adopting economic reforms, making them hotspots for growth among global stakeholders. Substantial growth in electrical and electronics, pharmaceutical, and chemical industries in the region and the resultant rise in product demand will also fuel the RO membrane chemicals market size in subsequent years.
