Oizom Instruments – A case study from Sanford, NC, USA

Hydrogen sulphide (H₂S) gas, commonly known as “sewer gas,” is a significant challenge for wastewater treatment plants. Its strong odour and potential health risks at low concentrations make it a frequent source of community complaints and operational concern. In Sanford, North Carolina, the local wastewater treatment plant regularly received reports from residents about unpleasant odours. H₂S is not only foul-smelling but also highly flammable, posing safety risks for workers and nearby citizens alike. Traditionally, plant operators had to rely on resident feedback before applying odour-control measures, a reactive approach that lacked precision and timely intervention.

Oizom system deployed at Sanford

To address this, the Sanford plant deployed an H₂S monitoring solution from Oizom. This real-time monitoring system tracks H₂S levels and identifies odour trends throughout the treatment process. The system’s advanced sensors measure gas concentration with precision and deliver real-time data through an online portal, allowing operators to monitor H₂S remotely. This proactive approach eliminates the need for manual checks and provides immediate data-driven insights, empowering the plant to manage odour more effectively and respond to potential spikes before they impact the community.

The data collected through Oizom’s monitoring solution has allowed for the design of an optimized H₂S suppression system for the Sanford facility, significantly improving odour control while ensuring a safer and more pleasant environment for both plant staff and residents.
