Drug storage and handling: First, chemicals are usually stored in dedicated tanks or containers. In these containers, the drug may need to be pre-treated, such as stirred, diluted or stirred, to ensure its uniformity and appropriate concentration.
Flow measurement: During wastewater treatment, the flow rate of wastewater is usually measured to ensure the correct rate of acceleration. Flowmeters are usually located at the inlet or outlet of the wastewater stream.
Drug dosing: Drug pumps are used to extract drugs from storage tanks and deliver them precisely into the wastewater stream. The running rate and dosage of the pump are usually controlled by the control system according to the monitoring data and preset parameters.
Mixing and reaction: Once drugs are added to wastewater, they must be thoroughly mixed to ensure uniform dispersion. In wastewater streams, chemicals can react with contaminants in a variety of ways, such as coagulation, neutralization, oxidation, or precipitation.
PH control: For wastewater treatment processes that require pH adjustment, the pH controller can be used to monitor the pH of the wastewater and automatically adjust the pH level required for drug administration maintenance.
Process monitoring: Throughout the dosing process, systems typically continuously monitor wastewater chemistry, turbidity, pH, and other key parameters to ensure that the treatment process is operating within a controlled range.
Automatic control: The dosing device is usually integrated into the automatic control system of the entire sewage treatment system, which can automatically adjust the drug dosing acceleration rate according to real-time monitoring data and preset parameters, so as to achieve efficient and accurate drug dosing.
Final treatment: After the wastewater is dosed, it continues to the subsequent steps of sewage treatment, such as precipitation, biological treatment, filtration, or other physicochemical processes, in order to achieve the required water purification and discharge standards.


Our chemical dosing unit precisely dispenses diverse chemicals in various industries, ensuring accuracy, safety, and efficiency, with features such as automation, monitoring, and material compatibility. And our dosing machine is suitable for different chemicals, such as:

In the oil and gas industry, dosing systems are utilized for injecting chemicals into extraction and refining processes, such as corrosion inhibitors, demulsifiers, and scale inhibitors.

01.Project Cases

  • Solved the later dosing device is corrosion risk
In purchasing a 1000L, 2.8kw fully auto dosing unit, the customer overlooked the issue of corrosion resistance.
Our company understands the Ph value of the customer's dosing, found that the medium is acidic and alkaline, they purchased 304 stainless steel corrosion resistance can not be reached, we recommend for the customer to use pp material box, steel lined with plastic mixing shaft and impeller.
For the customer to solve the later dosing device is corrosion risk.

02.Custom Cases

  • auto dosing systemCustomized the parts for customer
The customer wanted to buy a 1000L/h, 2.8kw caustic dosing system in communication with us, and We customized the parts for him:
Box: non-metallic pp material, enhance corrosion resistance.
Dissolving mixer: with 3 sets of 0.75kw, steel lined plastic shaft and impeller.
Dosing silo: with reducer, vibration pump, conveying system, can effectively prevent the crystallization of drugs.
Dosing pump: according to the customer's needs to choose metering pumps, screw pumps, centrifugal pumps, etc.
Control box
