MediSun Energy and Yanrun Membrane Technology are forming a Singapore-based joint venture to bring advanced water treatment and zero liquid discharge systems to industrial markets outside mainland China.
The partnership, announced at Singapore International Water Week 2026, will be led by MediSun Energy and positioned as the companies’ international route to market. Its focus is on industries under growing pressure to cut wastewater discharge, improve water reuse and manage high-salinity waste streams more effectively.
The venture brings together MediSun’s brine management platform and Yanrun’s electro-membrane research and manufacturing capabilities. Planned systems include electrodialysis bipolar membrane, electrodialysis metathesis, electrodialysis stack systems and pressurised forward osmosis technologies.
For industrial customers, the pitch is practical: reduce liquid waste, recover usable materials from brine and support compliance with tighter wastewater rules. That matters in sectors where water risk is becoming a boardroom issue, not just an operational one.
The companies are expected to focus on markets where desalination, heavy industry and water security are already shaping infrastructure investment. Southeast Asia and the Gulf Cooperation Council region are likely to be key targets, given their mix of industrial growth, water scarcity and rising demand for reuse-based systems.
The joint venture reflects a wider shift in industrial water management. Companies are no longer looking at wastewater treatment only as a cost of doing business. More are assessing whether difficult streams such as desalination brine and industrial effluent can be converted into recoverable resources.
MediSun’s role in the venture is tied to energy-efficient brine management, including reverse electrodialysis and CO₂ mineralisation. Its model centres on turning brine and industrial waste streams into usable outputs, which aligns with growing interest in circular economy and lower-carbon industrial operations.
Yanrun brings a manufacturing and R&D base focused on electro-driven and bipolar membrane technologies. Founded in 2010, the company has developed membrane systems for industrial applications and holds a portfolio of related patents. Through the Singapore entity, its technologies gain a clearer pathway into international markets.
Singapore gives the venture a practical base for expansion. The country has long positioned itself around water innovation and offers proximity to fast-growing Asian markets, while also giving the partnership a neutral commercial platform for customers outside China.
Execution will decide how far the venture can go. Advanced membrane systems need to prove reliability, cost performance and scalability across different industrial settings. For buyers in water-stressed markets, innovation is useful only when it works under real operating conditions.
