  • Integrated System for Monitoring Permeate Quality in Water Treatment Facilities
    Publication number: 20140319029
    Abstract: The invention provides a method and apparatus for continuous monitoring of permeate from membrane elements in a water treatment plant, including a desalination plant. The apparatus includes a probe that includes multiple sensors such that at least one sensor is associated with each membrane element. Each sensor is coupled to a node, which is configured to communicate a signal associated with the permeate quality to a central node sink. The node may communicate wirelessly with the node sink.
