WWA: Which part of a water treatment plant can wireless be used?There are many old water treatment plants that need to be modernised to meet new regulations without requiring additional manpower. For instance, in the past an operator had to walk into the plant to grab water samples and bring them back to the lab for analysis. This is a time consuming process, and unpleasant in bad weather. Today, those pains are alleviated with wireless. Wireless pH and other analysers can be deployed providing a continuous measurement automatically.The applications are everywhere: to protect reverse osmosis (RO) membranes; monitor disinfection at the final effluent; raw waters solids measurements, and treatment tank levels etc."
WWA: How can wireless technology add value to the water industry?Native wireless devices have integrated WirelessHART communication for wireless pH, conductivity, temperature, pressure transmitters and more. WirelessHART can be put to good use in various processes around water treatment, waste water treatment, and desalination plants. Hardwired 4-20 mA (HART) devices can be fitted with a WirelessHART adaptor and include chlorine, turbidity, level, dissolved oxygen, and Flowmetres with Smart Metre Verification enabling new solutions around these plants.
