3. Control System
Components: PLC-based Electric Control Cabinet, Level Gauges, Frequency Converters.
This versatile system is ideal for precise dosing in numerous applications:
Wastewater Neutralization: Acidic wastewater from mining, steel plants, coal mines.
Sludge Treatment: Conditioning and dewatering.
Water Treatment: Softening (de-hardening) in water plants.
Industrial Processes: Fluoride removal (photovoltaic industry), power plant FGD, dry powder dosing.
Pneumatic Loading: Powder is delivered by tanker truck through the feed pipe. The silo-top dust collector filters and releases air, ensuring a dust-free process.
Automated Level Control: High/low-level sensors trigger alarms and PLC signals for precise inventory management. The system automatically requests refills and can safely shut down if levels are critically low.
Precise Dosing & Mixing: On demand, powder is conveyed to the dissolving tank via a screw feeder. Water is added automatically, and a mixer creates a uniform solution.
Continuous Operation: Dosing pumps feed the solution to the application point. The PLC automatically initiates a new mixing cycle when the solution level drops, ensuring an uninterrupted supply.
Packing and Delivery
