CASE STUDY: Chlorine Monitoring

Leilani Johansen - August 17, 2021

Industry: Resources & Mining

CHALLENGES

  • Water quality
  • Risk to health and safety
  • Costly laboratory water testing

RESULTS

  • Improved water quality
  • Eliminated risk to health and safety
  • Streamlined water testing process and removed risk of human error

A leading global mining company maintains water treatment plant stores of raw water on one of their Australian mine sites. The water undergoes several treatments including chlorine  disinfection and is then reticulated throughout the mine site for human consumption. To ensure safe levels of chlorine, and therefore satisfactory health and safety of staff and the wider community, the water must be monitored and tested regularly. Previously, an external water testing laboratory would send personnel to site to sample the water, the sample would be sent to a testing facility, and a report would be generated. A more time streamlined solution was sought to save time, reduce costs, and eliminate the risk of human error, while providing the same level of data.

The Captis Multi EA solution was chosen, incorporating a Low Power Residual Chlorine and pH Sensor provided by our sensor partner, Verge Solutions. With a specially designed flow cell, the chosen sensor provided a seamless inline connection to existing plumbing, allowing for easy installation. Requiring a tailored solution, the Captis Multi EA was fitted with solar power, a charge controller, and a small battery, all to ensure uninterrupted sample logging. Chlorine levels in the water were sampled every 15 minutes and transmitted to our device management platform, once per day. Additionally, a trigger alarm was set in the event a particular chlorine threshold was met, notifying key stakeholders immediately.

By providing a proven and reliable technology, the customer was able to ensure the ongoing health and safety of their staff in addition to streamlining an otherwise time-consuming and costly water testing process.
