Typical Zero Liquid Discharge (ZLD) applications are seen as a solution for a specific problem resulting in projects being siloed as traditional wastewater treatment systems. This approach prevents the full impact and utilization of ZLD within the power industry. ZLD systems can utilize process or waste heat to drive evaporation, reclaim water, reduce waste, and reduce the consumption of resources such as water. Ultimately, this approach can have the greatest effect on a facilities environmental impact and risk. Zero Liquid Discharge systems are a combination of technologies that work together to minimize wastewater as much as technically and economically practical, often resulting in a concentrated solid product and high-quality clean water for re-use or environmental discharge. Integrating a ZLD system into your process increases resiliency by reducing both cost and risk. Zero Liqui Discharge works to secure control over your water source and waste disposal reducing the influence of factors outside of your control. In many applications, ZLD should be seen as a comprehensive solution utilizing all aspects of the power generator process. Waste energy can be used to concentrate waste stream and recover water for reuse within the facility.Water scarcity, new Fuel-gas desulfurization (FGD) regulations, and a circular economy are driving industries to rethink their business models from the ground up. Zero Liquid Discharge should be seen as an integrated solution for beneficial reuse of both water and energy within the power energy Maximization of energy utilization through capturing high-temperature waste heat normally discarded to the cooling towers is one example of how this can be achieved.
