The Membrane Science and Technology Institute of Jiangsu Industrial Technology Research Institute has developed an integrated water-treatment and reuse solution designed to address the shortage of high-quality water resources while reducing pollution discharge. The technology combines several self-developed membrane technologies with evaporation to recover reclaimed water from industrial parks and produce high-purity water for demanding applications.
Challenge
High-quality water is essential for both human needs and industrial production, while industrial activities can generate significant quantities of wastewater. The solution addresses the challenge of limited high-quality water resources by enabling water recovery and reuse rather than relying exclusively on new water supplies and conventional wastewater discharge.
Solution and Innovation
The system uses self-developed ultrafiltration, nanofiltration, reverse osmosis and electrodialysis membranes, integrated with evaporation technology. Together, these technologies reclaim water from industrial parks and produce high-purity water suitable for the water-electrolysis stage of green hydrogen production. The system is driven by wind power and is designed to achieve low operating costs, high-quality product water and zero-waste generation.
Applications and Scale
The solution has reached the Scaled / Replicated stage and is designed for deployment across different applications and contexts. It currently supports recycling of approximately 5,000 tonnes of high-quality water per day, while the technology can provide high-quality water at capacities ranging from 1 t/h to 10,000 t/h.
Beyond green hydrogen production, the technology can be extended to agricultural irrigation, domestic drinking water and other industrial applications, providing a flexible approach to water-resource recovery and reuse.
Climate and Resource Impact
By recycling high-quality water and avoiding pollution discharge, the technology supports more efficient use of water resources. Its application to green hydrogen production also connects water reuse with renewable-energy-based industrial development. The combination of water recycling, zero-waste operation and wind-powered treatment contributes to a more resource-efficient and climate-resilient industrial system.
