UV254 Monitors for Scottish Water

Six UV monitors (UV254Sense) from Pi are being used to form part of a major upgrade at Mannofield water treatment works in Aberdeen, by Ross-shire engineering (RSE). The upgrade is to improve the resilience and functionality of the water treatment works, with Scottish Water investing £8 million into the project.

RSE and Pi have a longstanding relationship in business. Due to this, when RSE decided to implement UV treatment and measurement, they knew they could rely on Pi to deliver the best products for the job.

UV monitors from Pi monitor both UVA (Ultra-Violet Absorbance) and UVT (Ultra-Violet Transmission) in real time. They monitor UVA and UVT by passing a low flow of sample water continuously through an auto-cleaning flow cell containing the measurement probe and by shining a light set at a wavelength of 254nm through the sample, thus measuring how much is absorbed (UVA), and how much is transmitted (UVT).

UV254 analysers from Pi allow for the detection of natural organic matter (NOM). Although UV254 is absorbed by all dissolved organics, the absorption is strongest for aromatic compounds making UV254 absorption particularly useful in the fight against disinfection byproducts (DPBs).
