Dosing equipment in wastewater treatment is one of the key equipment, which is used to add chemicals to wastewater to improve the treatment effect and ensure that the wastewater meets the discharge standards.
● Drug Storage & Handling ● Flow Measurement ● Drug Dosing ● Mixing & Reaction
● PH Control ● Process Monitoring ● Automatic Control
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 & 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 machine 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.
THE TYPES OF DOSING SYSTEM
There are many different types of dosing equipment in sewage treatment, and the appropriate dosing system can be selected according to its application, the nature of the chemical and the needs of the treatment process.
They are used to precisely add chemicals such as PAC and PAM to the water flow to improve coagulation, flocculation, precipitation, turbidity removal, and wastewater treatment.
Chemical dosing equipment is divided into different types, such as plunger pumps, screw pumps, centrifugal pumps, etc., according to the nature of the drug and dosing requirements to choose.
The dry powder dosing system can quickly and evenly dissolve or disperse the dry powder reagent into the wastewater, thus improving the efficiency of the chemical reaction.
Automatic chemical dosing unit has a highly accurate dose control function, which can ensure that the dosage of the chemical drug is within the specified range each time.
Manual dosing devices require the operator to manually control the dosing process, including starting, stopping, adjusting the dose and monitoring the dosing.
Dosing systems have a wide range of applications, and they play a key role in several industrial and environmental sectors for precisely adding chemicals, polymers, gases or other substances to a fluid stream to achieve a variety of treatment objectives.
The following is an introduction to the dosing system application
Chemical dosing water treatment
In wastewater treatment plants, systems are used to improve sludge sedimentation, remove pollutants from wastewater, degrade organic matter and improve wastewater treatment efficiency.
Industrial processes
Dosing systems are used in many aspects of industrial production, including pharmaceuticals, food and beverage production, paper making, chemicals, metal processing, etc. They can be used to precisely control production processes, improve product quality, and treat wastewater and liquid waste.
Environmental engineering
In environmental protection projects, dosing systems can be used for tasks such as groundwater treatment, soil remediation, gas purification, waste treatment and emission control.
