現今水處理過程中的大多數污泥排放都是通過傳統方法來控制，例如定時排放和經驗豐富的操作人員。傳統方法無法即時獲得沉澱池中的污泥厚度，因此無法有效地排放污泥，此方法的特點是低能量效率和低應變能力。本研究將即時精準多層式感測器（Real-Time Precision Multi-Layer Sensor, RTPMLS）用於檢測沉澱池中的污泥厚度。結果顯示，能在污泥排放過程中即時反應污泥厚度變化。此結果幫助水處理廠即時排放適當的污泥濃度，減少污泥脫水程序的運行次數，提高能源效率。未來將RTPMLS和物聯網（IOT）進行結合，可有效加強監測污泥沉降情形，進而提升給水廠供水穩定性。

Most sludge pumping in water treatment processes were manipulated by traditional approaches, such as definite time discharge and experienced workers. However, the traditional approaches cannot monitor real-time sludge thickness in a sedimentation tank. Thus, while the sludge discharge of the traditional approaches is independent to the sludge quantity in the sedimentation tank, the pumping interval of the sludge cannot be adjusted by water quality nor sludge quantity. Therefore, the traditional processes were struggled with low energy efficiency and low strain capacity. In this study, Real-Time Precision Multi-Layer Sensor (RTPMLS) for the sludge thickness detection in the sedimentation tank is proposed. With a series of experiments, we successfully demonstrate real time monitoring of sludge thickness during the discharging process. While the sludge can be discharged with appropriate concentration every time, it could reduce the operation frequency of dewater program. Thereby increasing the energy consumption efficiency. Compared to the traditional approaches, the introduction of RTPMLS stands for a more reliable sludge treatment program. In the future, the capability to connect RTPMLS and Internet of things (IOT) provides a massive potential to optimize the water treatment program, which can enhance the sludge thickness monitoring ability.
