Membrane Condenser for Efficient Dehydration, Waste Heat Recovery & Water Reclamation

Industries involved in dehydration processes often face significant challenges, including high energy consumption, excessive water usage, and limited capacity to recover waste heat efficiently. These inefficiencies lead to increased operational costs, wasted resources, and a substantial environmental footprint, including higher carbon emissions and water wastage. 

This technology offers an innovative solution to these challenges by utilizing specially engineered membranes to condense water vapor from hot and humid air or gas streams. This process not only produces high-quality liquid water for reuse but also dehumidifies and cools the gas stream, which can be recirculated to absorb low-grade heat for further material dehydration. By integrating membrane condensers into industrial operations, companies can improve energy and water efficiency, recover valuable resources, reduce cooling water needs, and minimize emissions and environmental impact. With applications spanning HVAC, food drying, ingredient concentration, desalination, and wastewater treatment, this versatile technology enables industries to lower costs while achieving more sustainable and eco-friendly operations. 

The tech owner seeks industrial partners for test-bedding and potential adoption of their proprietary technology, particularly in sectors like F&B, laundry, commercial buildings, petrochemical, pharmaceutical, energy, wastewater treatment, or any industries using water-cooling or air-drying processes. 

The membrane condenser technology features a core component of hollow fiber gas separation membranes, housed within a large module. These membranes, made from polyvinylidene fluoride (PVDF), are semi-permeable and hydrophobic, offering long-lasting hydrophobicity, sustainable high flux, high mechanical strength, and the ability to operate across a wide temperature range. The system functions by integrating the membrane module with auxiliary equipment such as evaporators or dryers, heat exchangers, blowers or heat pumps, pipelines, and instrumentation control systems. This modular and versatile design allows for seamless integration into various industrial processes, particularly in sectors such as petrochemical, chemical, pharmaceutical, energy, food and beverage, and wastewater treatment.
