The coagulant dosing station is designed for the preparation of a working solution of a coagulating reagent and its precise dosing into water treatment or wastewater treatment systems.
A coagulant is the first step toward stable treatment performance.
It destabilizes colloidal particles, binds fine suspended contaminants, and forms flocs that are subsequently removed in clarifiers or flotation units.
If coagulant dosing is unstable, the entire treatment process becomes unstable.
The station ensures full control and stability of this critical stage.
THE PRINCIPLE OF OPERATION
The unit is a технологический module consisting of:
- Solution preparation tank
- Day (storage) tank
- Dosing pumps
- Flow meters and rotameters
- Shut-off and control valves
- Process pipelines
- Mixing system
- Automated control cabinet
1. Solution Preparation
In the preparation tank, the reagent solution is mixed to the required concentration.
Homogeneity is achieved using mechanical agitators or pneumatic air sparging.
2. Storage and Stabilization
The prepared solution is transferred to the day tank, where the required volume is maintained to ensure continuous and stable dosing.
3. Precise Dosing
Dosing pumps inject the reagent into the water flow proportionally to flow rate or based on automation signals.
Dosing accuracy is maintained within 2–3%, ensuring stable technological parameters.
The coagulant station can operate in fully automatic mode and synchronize with flow meters, turbidity sensors, or signals from the wastewater treatment plant control system.
Proportional injection with minimal deviation ensures stable coagulation performance.
The system operates without constant operator supervision.
Suitable for dosing liquid reagents, acids, and alkalis depending on the process scheme.
Optimized dimensions allow installation in confined areas of WWTP facilities or water treatment plants.
User-friendly control interface and convenient access to service components.
