PAC dosing device

 

PAC dosing device is a device used to accurately add polyaluminum chloride (PAC) agents into water treatment systems. The following is a detailed introduction about it:

component

Solution tank: used to dissolve PAC agents, generally made of corrosion-resistant materials such as polyethylene, fiberglass, etc., to ensure that it can withstand the corrosiveness of the agents.

Blender: installed in the solution tank, used to stir PAC agent and water to fully mix and dissolve, forming a uniform PAC solution. The speed of the mixer can usually be adjusted as needed to achieve the best mixing effect.

Metering pump: It is one of the core components of PAC dosing device, responsible for accurately delivering PAC solution from the solution tank to the water treatment system according to the set flow rate and pressure. The flow rate and pressure of the metering pump can be precisely adjusted according to specific dosing requirements.

PAC dosing device

Liquid level gauge: installed in the solution tank, used to monitor the liquid level height of PAC solution in the solution tank in real time. When the liquid level is lower than the set value, the level gauge will send a signal to remind the operator to replenish the medicine in a timely manner.

Control system: It is the brain of the PAC dosing device, which achieves automated control of the entire dosing process by controlling the start and stop of the metering pump, adjusting the speed of the agitator, and monitoring the signal of the liquid level gauge. Control systems typically have two control modes, manual and automatic, for flexible operation in different situations.

working principle

The working principle of PAC dosing device is to accurately add pre configured PAC solution to the water to be treated through a metering pump. During the water treatment process, PAC agents undergo flocculation reactions with impurities in the water, forming larger flocs. These impurities are then removed through processes such as precipitation and filtration to achieve the goal of purifying water quality.

characteristic

High degree of automation: It can achieve automatic dispensing and dosing, reducing the workload and errors of manual operation, and improving the accuracy and stability of dosing.

High dosing accuracy: The precise metering function of the metering pump ensures accurate dosing of PAC solution, thereby ensuring the stability of the water treatment effect.

Strong reliability: All components of the PAC dosing device are made of high-quality materials and advanced manufacturing processes, with good corrosion resistance and wear resistance, and can operate stably for a long time.

Easy and convenient operation: The control system has a simple and intuitive interface, and operators only need to perform simple settings and operations to control the dosing device.

Wide applicability: PAC dosing devices can be widely used in various water treatment fields, such as waterworks, sewage treatment plants, industrial circulating water systems, etc.

application area

Tap water treatment: In the coagulation and sedimentation process of water plants, PAC dosing devices are used to add PAC agents, remove suspended solids, colloidal substances and other impurities in water, and improve the clarity and transparency of water quality.

Wastewater treatment: During the wastewater treatment process, PAC dosing devices can be used to enhance the coagulation and sedimentation effect of wastewater, remove pollutants such as organic matter and heavy metal ions, reduce the color and turbidity of wastewater, and meet discharge standards or reuse requirements.

Industrial circulating water treatment: In industrial circulating water systems, PAC dosing devices can be used to control the formation of scale, inhibit the growth and reproduction of microorganisms, prevent equipment corrosion, extend the service life of equipment, and improve the utilization rate of circulating water.
