How to recover cooling tower evaporation loss. Reduce blow down. Under normal cooling tower operations, ALI captures and recovers evaporative water which may save in operating expenses. . Jul 5, 2020 · Six methods are found in open literature, which are: using air-to-air heat exchanger, psychrometric properties, nanofluid technology, hybrid wet-dry cooling towers, porous media and the method investigated in this paper using filters. Because evaporation consists of pure water, the concentration of dissolved minerals and other solids in circulating water will increase. Reduce chemical treatments. The main findings of each method are provided next. Your solution should capture water vapor through evaporation and return it to the cooling tower’s cold-water basin for reuse. For example, for a cooling tower that recirculated 800 m3/h of water, the inlet temperature is 42ºC and the outlet temperature is 35ºC with 1% evaporation loss. ALI reduces the need for expensive chemicals to treat water impurities and bacteria by recovering and recycling water. At the same time, the chemistry of the water remaining in the cooling tower is changing. The cooling tower rejects more heat to the atmosphere by evaporating a portion of the water in contact with the air. Jul 26, 2025 · Beyond technology, routine cooling tower maintenance is crucial to water conservation. Scale buildup, clogged nozzles, or leaking valves can silently increase water loss over time. com Both open and closed circuit cooling towers use latent heat transfer to drive heat rejection. Design a cost-effective retrofit system to recover water vapor from a mechanical draft cooling tower at an inland power plant of your choice that faces water scarcity.
