Why Oxidation Ditch + Real‑time Monitoring Works?

Advantages of the Oxidation Ditch process:

- The long hydraulic retention time and sludge retention in the ditch allow both suspended and soluble organics to be degraded thoroughly. 
- The process design is simple with minimal structures, enabling either a single combined clarification or no primary clarifier at all; this simplifies operation and maintenance.
- Due to extended sludge age, discharged sludge tends to be stable, requiring only thickening and dewatering — sludge digestion tanks may be omitted.

Challenges / Limitations:

- Oxidation ditches typically require larger land area compared with conventional activated‑sludge basins, due to the geometry and hydraulic layout. 
- Mechanical aeration consumes more energy, leading to higher operational costs. 

How Sinomeasure’s Instruments Help:  

By installing online pH, DO and turbidity instruments, operators gain continuous, real‑time insight into critical biological treatment parameters. This enables:

- Rapid detection of process deviations (e.g. pH swings, oxygen depletion, turbidity fluctuations)
- Timely adjustment of aeration and sludge control to maintain optimal biological activity and effluent stability
- Assurance of effluent quality and compliance with discharge standards
- Reduction of manual sampling workload, and improved automation and process traceability.
