Real Spectrum UV-VIS sensors from Real Tech provide instant visibility into wastewater by delivering real-time accurate BOD data. The sensors can monitor up to 120,000 mg/L BOD with optional dilution system to meet the demands of various wastewater applications. Automatic chemical cleaning and purging systems minimize maintenance and ensure reliability in harsh environments. The sensor and optional accessories connect to a central controller that offers multiple communication options for easy integration to a SCADA system. With up to the minute BOD insights, important events can be detected prior to the five-day laboratory results, helping operators to control and optimize wastewater treatment processes. As a result, energy and chemical usage can be reduced to save costs while improving water quality. 905/665-6888; www.realtechwater.com.
