Real‑Time Online Ammonia Concentration Monitoring for Chemical Plants: Gas Sensor Solutions

Sludge treatment plants generate large volumes of ammonia during operation. Ammonia is a colourless gas with a pungent, irritating odour. It can burn the mucous membranes of the skin, eyes and respiratory organs. Excessive inhalation may cause pulmonary oedema and even death. Therefore, ammonia protection in sludge treatment plants is highly necessary and a mandatory preventive measure.
Many people are unfamiliar with the functions and operating principles of sludge treatment plants, let alone the substantial ammonia produced during sludge processing. Sludge treatment plants carry out reduction, stabilisation and harmless‑treatment processes including sludge thickening, conditioning, dewatering, stabilisation, drying and incineration. How should we address ammonia emissions generated during these harmless‑treatment workflows?

Conventional protective measures such as gas masks and anti‑corrosion personal protective equipment are no longer sufficient for mitigating potential ammonia hazards in sludge‑treatment workflows. Accordingly, ammonia leak alarms can detect ammonia concentration rapidly, accurately and stably, enabling intelligent protective responses to eliminate risks at the earliest possible stage.

Online Ammonia Monitoring Solution for Sludge Treatment Plants

It is recommended to install ammonia leak alarms at sewage tanks, discharge outlets and other relevant locations. Ammonia leak alarms serve as an effective means for gas‑concentration detection. They monitor toxic and harmful gas concentrations in real time. Once the measured ammonia concentration exceeds preset thresholds, the alarms will immediately trigger audible‑visual alerts or interlock with exhaust fans, prompting personnel to evacuate urgently or implement countermeasures, which effectively prevents hazardous accidents.

The core component of ammonia detectors is the ammonia gas sensor. Shenzhen Wuliang Technology Co., Ltd. recommends the British electrochemical ammonia sensor (NH₃ sensor) GS+4NH3‑1000. It is mainly used to measure ammonia concentration in ambient air. Featuring linear current output for easy signal processing and high sensitivity, it is well‑suited for harsh operating environments.
