This report evaluates a novel method of increasing the efficiency of an evaporative process to recycle three types of industrial waste waters; power plant cooling tower blowdown, industrial steam generation blowdown, and an acidic mine drainage type of wastewater. The method, known as interface enhancement, involves the addition of a surfactant to the wastewater stream prior to passing the stream through a vertical tube evaporator. For all three waste streams a considerable increase in heat transfer performance was observed. It was concluded that substantial capital and operating cost savings could be realized by modifying existing evaporation systems to accommodate the interface enhancement technique.
