MediSun and Yanrun Announce Global Water JV

MediSun Energy and Yanrun Membrane Technology Co., Ltd. have announced a strategic joint venture and will establish a new Singapore-based entity to take advanced water treatment and zero liquid discharge systems to markets outside mainland China. Announced at Singapore International Water Week 2026, the venture will be led by MediSun Energy and will focus on Southeast Asia and the Gulf Cooperation Council region. Its offering will include electrodialysis bipolar membrane, electrodialysis metathesis, electrodialysis stack and pressurized forward osmosis systems, alongside integrated zero liquid discharge solutions. Yanrun holds 47 national invention and utility model patents.

Singapore Based Global Platform

The new entity will serve as the companies’ exclusive global launchpad outside mainland China. MediSun Energy contributes its international network and brine management capabilities, while Yanrun brings its R&D legacy in advanced electro-driven and bipolar membranes.

The two companies will collaborate to address critical water scarcity and tightening industrial environmental regulations globally.

Dusun Kim, CEO & Co-Founder of MediSun Planet Pte Ltd, stated:

“The global industrial market is facing an inflection point where conventional wastewater disposal is no longer sustainable, environmentally compliant, or economically viable. By combining MediSun Energy's international market reach and deep-tech brine management capabilities with Yanrun's world-class, multi-patent electro-membrane manufacturing engine, this partnership will bridge a critical industry gap. We are excited to offer heavy industry and desalination sectors across Southeast Asia and the GCC region access to next-generation, circular ZLD solutions that turn environmental liabilities into valuable resource streams.”

Membrane Systems For Reuse

The joint venture’s technology portfolio combines membrane-based separation systems with zero liquid discharge design. Electrodialysis bipolar membrane, electrodialysis metathesis and electrodialysis stack systems will sit alongside pressurized forward osmosis equipment.

Founded in 2010, Yanrun operates manufacturing facilities in Mianzhu and Quanzhou and produces tens of thousands of square meters of monolithic bipolar and homogeneous exchange membranes each year. The company has participated in national-level initiatives including China’s 863 Plan.

Huang Quansen, Chairman of Yanrun, added:

“Yanrun has consistently spearheaded the development, industrial application, and industry standard-setting of advanced electro-driven membranes within China. Establishing this exclusive international commercial platform alongside MediSun Energy marks a pivotal milestone in our global expansion strategy. This partnership allows us to seamlessly match our manufacturing excellence and cutting-edge membrane technology with MediSun Energy's prominent international presence, bringing clean, green, and circular industrial water reuse technologies to the global stage.”

Focus On Industrial Brine

MediSun Energy specializes in integrated brine management, including systems intended to turn desalination brine and industrial waste streams into resources. Its technology portfolio includes reverse electrodialysis and CO₂ mineralization for desalination and heavy-industry applications.

The joint venture will drive the international development, manufacturing and distribution of the combined systems. By anchoring the initiative in Singapore, the companies say they are positioned to leverage the nation’s business ecosystem to accelerate global climate resilience, decarbonize heavy industry and promote long-term water security.
