The global RO Membrane Market size is projected to reach USD 5.0 billion by 2026 from USD 3.1 billion in 2021, at a CAGR of 10.0% during the forecast period.

Recent Developments
+ In January 2020, DuPont Water Solutions launched dry-tested seawater reverse osmosis elements which will enable the transition from wet to dry testing and increase shelf life and flexibility for storage. It aims to exceed membrane performance standards and achieve long-term operational benefits.
+ In December 2019, Toray Industries, Inc. created a seawater desalination reverse osmosis membrane. This membrane can produce 70% cleaner water than other conventional offerings. This technology helps in the reduction of water production cost and aims to fulfill global demand of clean water.
+ In October 2020, Koch Industries partnered with Waste 3R Engineering & Solutions. The partnership aims to promote company’s advanced separation technologies for industrial water and wastewater projects across Bangladesh and help to achieve the recycling and reuse by leveraging the company’s membrane products and system.
+ In November 2020, LG Chem supplied RO membrane to Al Khobar II project, in the Kingdom of Saudi Arabia. The plant has production capacity of 600 million liters per day (MLD). The project aims to meet the water quality requirements with low energy consumption.

Market Dynamics
+ Driver: Government regulations and increasing demand of clean drinking water
The government regulations and increasing demand for clean processed drinking water are driving the water and wastewater treatment industry.

+ Restrain: Membrane fouling and scaling
RO membrane continues to increase in demand with the growth of the water treatment sector. However, fouling and scaling are its major drawbacks. Fouling occurs in both cellulose-based and thin-film composite membranes.

+ Opportunity: Growing demand from emerging economies
The need for water desalination from seas and oceans is likely to increase in the developing countries. Countries in the MENA and South America are establishing water desalination and brackish water treatment units to deal with water scarcity problems.

+ Challenge: Discharge of dense brine
Brine is generally defined as water with a salt concentration higher than 50 parts per thousand, though some brines can be several times saltier.
