Industrial Diaphragm Dosing Pump , Automatic Dosing System For Wastewater Treatment

Dosing System: Applied in water/wastewater treatment, industrial processes, chemical reagent dosing, etc.

Quick Details

Precise chemical reagent dosing is a core process that ensures process efficiency, improves water quality, reduces operational costs, and guarantees stable system operation. The fully automatic intelligent dosing system we provide is specially designed for key processes such as pH adjustment, coagulation, and flocculation. Through the closed-loop control of "real-time monitoring - intelligent calculation - precise dosing", it completely eliminates reliance on manual labor and empirical judgment, achieving optimization of chemical dosing and full-process automation.

System Core Components and Working Principle

This system is a complete electromechanical integration unit integrating three functions: sensing, decision-making, and execution.

Sensing Unit: On-line Water Quality Analysis Instruments

pH/ORP Controller: Continuously monitors the pH value or oxidation-reduction potential of the process water, providing real-time data for acid-base neutralization or redox reactions.

Turbidity/Suspended Solids (SS) Analyzer/Streaming Current Detector (SCD): Real-time detects the effect of coagulation and flocculation, providing direct or indirect feedback signals for the dosing of coagulants and flocculants.

Flow Meter: Monitors the treated water volume, providing a benchmark for proportional dosing.

Decision-making Unit: Intelligent Control System

Calculates and outputs control commands in real time according to preset control logic (such as PID control, feedforward-feedback composite control) and set values.

Equipped with a Human-Machine Interface (HMI) for parameter setting, mode switching, operation status display, and historical data query.

Execution Unit: High-precision Dosing Module

Chemical Storage Tank: Made of corrosion-resistant materials (PE, FRP, stainless steel), equipped with liquid level indication and alarm functions.

Precision Metering Pump: The core executive component, enabling stepless and precise adjustment of dosing volume. Diaphragm pumps, plunger pumps, etc., are available as options.

Agitation System: Ensures uniform concentration of chemicals in the storage tank and prevents sedimentation.

Safety and Auxiliary Components: Including back pressure valves, pulsation dampeners, injection valves, Y-type filters, etc., to ensure stable and reliable operation of the dosing pipeline.

Application Scenarios

Water and Wastewater Treatment: Coagulation and flocculation in the pretreatment of municipal and industrial wastewater, pH neutralization; coagulant dosing in waterworks; PAM dosing for sludge dewatering conditioning.

Industrial Processes: Dosing of corrosion and scale inhibitors, bactericides in circulating cooling water; pH adjustment and oxygen scavenger dosing in boiler feedwater; precise pH control in technological processes.

Other Fields: Swimming pool water treatment, food processing, pharmaceuticals, electronic ultrapure water, and other occasions requiring precision chemical dosing.
