Application Overview
In wastewater treatment processes, precise and reliable dosing of treatment chemicals is essential to ensure effective pollutant removal, stable process control, and regulatory compliance. Chemical dosing metering pumps are widely used for the accurate injection of coagulants, flocculants, pH adjustment chemicals, disinfectants, and other treatment agents throughout municipal and industrial wastewater treatment systems.
Wastewater characteristics often fluctuate due to changes in influent quality and flow rate, requiring flexible and accurate chemical dosing. Metering pumps provide high-precision, repeatable, and controllable dosing performance, enabling automated chemical addition based on real-time process parameters. Integrated with PLC systems and online analyzers, chemical dosing metering pumps play a critical role in maintaining treatment efficiency, reducing chemical consumption, and improving overall system reliability.
Typical Applications
Coagulant and Flocculant Dosing
Accurate dosing of PAC, PAM, iron salts, and aluminum salts to enhance solid–liquid separation and improve sedimentation efficiency.
pH Adjustment and Neutralization
Precise injection of acids or alkalis to control pH levels in influent, process tanks, and effluent discharge.
Disinfection and Oxidation Processes
Dosing of sodium hypochlorite, chlorine dioxide, hydrogen peroxide, and other disinfectants to ensure effective pathogen removal.
Sludge Conditioning and Treatment
Controlled addition of conditioning chemicals to improve sludge dewatering and handling performance.
Industrial Wastewater Chemical Treatment
Used in chemical dosing systems for heavy metal removal, oil separation, and advanced treatment processes.
