Case study: determine plant performance on Phosphorus removal
May 4, 2023
Hach Phosphax sc Low Range Analyzer 水中磷酸鹽線上分析儀準確可靠，可用於量測範圍為 0.015 – 2mg/l 的正磷酸鹽，於此應用實績，英國某水務公司採用 Hach Phosphax sc LR 磷酸鹽線上分析儀以評估污水處理廠去除污水中磷的能力，協助專案團隊確定將最終流出物中的正磷濃度降至<0.25 毫克磷所需的最少附加程序的範圍。 這可能為相關的自來水公司節省大量成本，為未來的水處理程序設計提供了關鍵資訊。
Using a Hach Phosphate online analyser, a UK water company was able to assess the capability of a wastewater treatment plant to remove phosphorus and to assist with informing future process design.
The instrumentation was provided for a three month trial in order to assess the accuracy and robustness of the analyser, increase its familiarity with operators and importantly to determine the P removal capability of the process stream up to an including the ASPs.
Conclusion of the study
• The Hach Phosphax sc LR is a reliable and accurate instrument for the determination of orthophosphate in the range 0.015 – 2mg/l as P
• The wastewater treatment plant was capable of regularly reducing ortho P concentrations to <0.5mg/l after the ASPs though careful management of the process. This was previously regarded as being in the range 0.6 – 3.3 mg/l as P
• The trial has assisted the project team with the scoping of the minimum additional processes required to reduce ortho P concentrations to <0.25mg as P in the final effluent. This may allow significant cost savings for the water company involved
