Chemical Dosing Systems
Precision Dosing for Reliable Water Treatment Outcomes
Chemical dosing systems play a critical role in water and wastewater treatment by ensuring the accurate and consistent introduction of treatment chemicals into the process stream. Whether for pH correction, coagulation, disinfection, antiscalant injection, or oxidation, precise dosing enhances process efficiency, safeguards equipment, and ensures regulatory compliance.
BT Water designs and manufactures fully integrated, skid-mounted chemical dosing systems engineered for industrial applications. Each unit is tailored to process requirements, with robust construction, high chemical compatibility, and seamless automation options.
Applications
- Reverse Osmosis (RO) pre-treatment (antiscalant, sodium metabisulfite, acid dosing)
- Effluent and sewage treatment plants (coagulants, flocculants, pH correction)
- Cooling towers and boilers (biocides, scale inhibitors)
- Disinfection (chlorine, sodium hypochlorite, hydrogen peroxide)
- Process industries (paper, pharma, food, chemical)
System Configuration
| Component | Specification |
|---|---|
| Chemical Storage Tank | HDPE / FRP / PP construction, volume based on dosage and autonomy required |
| Dosing Pump | Electromagnetic or motor-driven (diaphragm/plunger type) with flow accuracy of ±1% |
| Skid Base | MS powder-coated / SS304 frame with anti-vibration pads |
| Piping & Valves | Chemical-resistant PVC/PP/HDPE piping with NRVs, isolation valves |
| Calibration Cylinder | For pump flow verification |
| Instrumentation | Level sensors, flow meters, pressure relief valves, pressure gauges |
| Control Panel | Manual, semi-automatic, or PLC-based with SCADA/BMS integration options |
Pump Selection Guide
| Application | Typical Pump Type | Flow Range | Pressure Range |
|---|---|---|---|
| Antiscalant | Electromagnetic | 1–10 LPH | 4–10 bar |
| Acid / Alkali | Motor-driven diaphragm | 5–100 LPH | 4–7 bar |
| Flocculant | Motor-driven plunger | 2–30 LPH | 3–5 bar |
Automation & Integration
Our systems support automation based on:
- Flow-proportional dosing (linked to main process flow)
- pH/ORP controller-based feedback dosing
- Timer-based dosing
- Remote monitoring & control through IoT or SCADA
