The UV254Sense UVA/UVT monitor provides real time organic UVA (ultra-violet absorbance) and UVT (ultra-violet transmission) analysis. The real time monitoring of organics in water has improved greatly with technological improvements in spectral analysis of the ultraviolet light range using the UV254 analyzer which as standard comes with UV transmittance and UV absorbance outputs. It does this by passing a low flow of water continuously through a fixed silica cuvette and by shining a UV254 light through the water measuring how much is absorbed (UVA) and how much is transmitted (UVT).

Benefits

• UVA (ultra-violet absorbance) is an excellent surrogate parameter for TOC, DOC, COD and color.
• UVT (ultra-violet transmission) allows for the calculation of optimal UV dose for disinfection systems, improving efficiency.
• Accurate detection without the cost of reagents.
• Few ongoing service or maintenance requirements.
• Allows feed forward optimization of coagulation control, resulting in decreases in chemical consumption, reduction in sludge removal costs and minimization of DBP formation potential.
• Strong ROI with pay back on the analyzer being seen by many customers within a few months.
• UVA measurement ensures performance of various contaminant removal technologies such as membranes (RO, NF, UF), ion exchange (nitrates and TOC removal) and granular activated carbon (GAC).
• Real time UVA analyzers can provide a final check of effluent water quality and can alarm an operator in case of non-compliance.
• A UVA monitor can monitor the percentage removal of organics across any treatment system.
• Can be combined with a CRONOS^® or CRIUS^® for a multi-parameter UV254 analyzer solution that suits your needs.
