Incoming, in-process and outgoing (effluent) water in manufacturing plants is regularly monitored by Operations and Maintenance (O&M) personnel. This is done so that the quality control specifications are met; the wastewater treatment processes are optimised and all federal, state and/or local regulatory requirements are complied with.

Water quality monitoring processes as a rule involve comparatively expensive and lengthy grab sample and chemical lab testing. Due to this fact, more end users are implementing more efficient, quicker monitoring systems with compact UVC LED-based sensors.

The sensors make use of UV photometry to identify water contaminants in real time, collecting data about water quality at various locations throughout a plant’s incoming and outgoing water network. This allows O&M personnel to immediately identify and correct water quality issues within hours instead of having to first wait for grab sample and laboratory testing results, which reduces the risk of costly regulatory compliance violations as well as overall O&M expenses quite radically.

Advancements in high-performance UVC LEDs allow design engineers to reduce the costs of the sensor by between 40% and 80% while still developing powerful yet small instruments that are tailored to specific water quality measurement applications.

These smaller, more efficient LED-based sensors can provide more efficient benefits to industries, including the food and beverage industry. Continuous spectroscopic sampling will enable O&M personnel at food and beverage facilities to efficiently and quickly monitor process information, to detect water quality issues and to make the necessary changes in real time.

The major advancements in UVC LEDs allow instrument manufacturers to develop flexible water quality monitoring sensors at 40% to 80 % of the cost of a lamp-based system, which is a massive benefit in developing countries. Another benefit is that these tiny powerful sensors can be custom-made to address industry or plant-specific water quality measurement requirements.
