Application Notes

Water Treatment:
pH controllers are crucial in wastewater treatment (ETP/STP plants) and drinking water systems, where they regulate chemical dosing to ensure water safety and prevent corrosion or scaling. 
Chemical Processing:
In chemical plants, pH controllers maintain optimal pH levels in reactors, mixing tanks, and other processes, ensuring efficient reactions and product quality. 
Food and Beverage:
pH controllers are used in food and beverage production for processes like fermentation, CIP (cleaning in place), and controlling the acidity of products like beer and wine. 
Agriculture:
pH controllers help monitor and adjust soil pH for optimal crop growth and are used in hydroponics and aquaculture. 
Mining:
pH control is important in mining operations, especially in water recycling and runoff management to prevent environmental damage. 
Pharmaceuticals and Cosmetics:
pH is critical in the production of pharmaceuticals and cosmetics. pH controllers ensure that products are within the required pH range for safety and effectiveness.
Cooling Towers:
Maintaining the correct pH in cooling towers prevents corrosion and scaling of the system.
Aquaculture:
pH controllers are used to maintain optimal water quality for fish and other aquatic organisms in aquaculture systems.
