MediSun Energy, a Singapore-based leader in brine management, has signed two significant Memorandums of Understanding (MoUs) with GreenTech Environmental, a Chinese innovator in water treatment, at the Global Water Expo in Riyadh. These agreements aim to advance modular desalination, promote Saudi localisation, and support global expansion.
The collaboration combines MediSun’s technologies—Reverse Electrodialysis (RED) and Selective Electrodialysis Metathesis (SEDM)—with GreenTech’s Newater House, a containerised desalination solution. This integration is designed to improve efficiency, reduce energy consumption, and minimise brine discharge in both Brackish Water Reverse Osmosis (BWRO) and Seawater Reverse Osmosis (SWRO) systems.
Under the first MoU, MediSun will distribute Newater House across the Middle East and Africa, whilst GreenTech will introduce MediSun’s technologies in China. The second MoU focuses on Saudi Arabia through MediSun Arabia, a joint venture with MOAJ Holding. This partnership aims to build local capacity by establishing manufacturing, technology transfer, and training programmes within the Kingdom.
Joseph Chua, Co-Founder and President of MediSun, stated, “Partnering with GreenTech marks a major step forward. Together we are accelerating the rollout of the modular Newater House whilst expanding into key markets.” Eric Zhang, Chairman of GreenTech Environmental, added, “This collaboration unites international innovation with Saudi strength.”
The partnership aligns with Saudi Vision 2030, aiming to enhance water security, create jobs, and position Saudi Arabia as a global hub for innovative water solutions. The partners plan to export sustainable water solutions worldwide, strengthening domestic and international water security.
