TEST & MEASUREMENT FEATURE
parts such as tubing, measurement cells and seals and diaphragms on a yearly or bi-annual basis.
7. RECOMMENDED FREQUENCY Given the diverse range of parameters that are measured in water and waste treatment processes, it is difficult to set a universal rule when it comes to setting the frequency of maintenance checks. In most cases, it is possible to create a maintenance routine by monitoring the nature of past breakdowns with any issues that have been recorded, such as fouling, abrasion or measurement variations. By using these as a guideline, it will then be possible to create a maintenance routine that can help to safeguard against future occurrences. In addition, information from the device manufacturer should also be taken into account in order to further optimise performance.
8. CONSIDER THE LIFECYCLE Another factor that can affect the way that an analyser is maintained is where it sits in its lifecycle. This should take into account the model, age and make of the analyser. Models that are at the start of their product lifecycle will be well- supported, with ready spares availability. This may differ for models from older product ranges, where spares and the
expertise to service them may not be as readily available. Dealing with reputable manufacturers can help to minimise this, as they are more likely to be able to support older products or else to recommend a suitable upgrade path with an alternative replacement.
SUMMARY The important role played by continuous water quality analysers in safeguarding the quality of both potable and treated waste water makes it critical to ensure they are kept in top working order.
It is important to ensure that reagents are replenished as soon as they are exhausted
With water quality analysers being very much on the front line of every water treatment process, the need to ensure they are kept in good working order is of paramount importance in order to avoid any penalties arising from a failure. Following the steps outlined in this
article will provide a useful starting point for helping to design an effective maintenance strategy and prolong the life of continuous water analysers.
