Smart Storm partnered with Photonic Measurements of Northern Ireland to design and develop the UV254 smart meter, which incorporates advanced sensor technology to measure COD, BOD, TOC and DOC.

Whether it is measurement for aeration management, chemical dosing or monitoring UV disinfection performance, UV254 measurement will provide a fast, responsive and cost-efficient means of optimising process, at a fraction of the price of comparative mainstream products.

Measuring the level of COD via surrogate measurement is important in the optimisation of the oxygen levels in effluent water due to its effects on aquatic life and COD is always a consent parameter for trade effluent discharge. It is probably the most important indicator of water quality, but measuring COD, BOD, TOC and DOC has always been difficult, resulting in costly systems.

Using UV technology, the advanced UV254 sensor is able to detect the organic species found in water and waste water, in particular the organic material that can cause the most harm. These are the aromatic organics with their double ring carbon structure. This makes them, therefore UV254, excellent at detecting potential of chlorination disinfection by products (DBPs) such as Trihalomethanes (THMs). Organic water parameters such as TOC, DOC, BOD and COD can be correlated to the absorption UV light at 254nm.
