Automatic PAC Dosing Device for Waste Water Purification

What Is An Automatic PAC Dosing Device :

In many industries like waste water purification, printing and dyeing etc., usually we are required to dose some chemical solution into water or other liquids by a certain proportion. For example to dose coagulant and coagulant into waste water to achieve sedimentation.

Manufacturing process and dosing operation are both continuous, that requires a multi-functional dosing system which can both prepare and dose chemical solution in certain time and in certain quantity.

ZRY automatic PAC dosing device is specially designed for these applications. 

Working Principles of Automatic PAC Dosing Device:

Powdered flocculant firstly access into pre-mixer through screw propeller to pre-mix with water. Then it is deliveried to preparation chamber and is diluted there in required concentration.

PAC dosing device will vary automatically with water inflow changes, thus well guarantee same solution concentration in the whole preparation process.

Diluted solution then enter into digestion chamber for digestion, and is finally stored in storage chamber. Preparation chamber and digestion chamber are both equipped with multi-propeller stirrer to guarantee the dilution and aging effect.

Solution preparing process is completed step by step. Different chambers are separated with each other to avoid any direct access between preparing chamber and storage chamber. Thus ensuring the best reaction time and a constant concentration in each solution chamber.

Automatic control system is connected with liquid level controller in storage tank. When liquid level exceed limited height, preparation process will stop automatically, and when liquid level down back to preset height, preparing process will automatically start again. 

As an experienced manufacturer started in year 2006, we provide one-stop services from project design to manufacturing, installation and final commissioning, professional services with cheap factory price automatic PAC dosing device for you.

Product features of Automatic PAC Dosing Device:

• SS304 or PE material, with excellent anti-corrosion performance.
• Whole process is continuous and automatic, easy to operate and maintain, low labor costs.
• Designed for both powdered and liquid chemicals, suitable for different applications.
• With proportional control function, can prepare required solution with different concentration.
• When chemicals in feed hopper is less than preset quantity, the inside sensor will give a warning signal and stop preparation process, safe and reliable.
• Unique designed intermittent stirring function, stirrer will work intermittently in stand-by time to ensure thorough mixing of solution, and keep solution in the best state.
• Powder feed hopper is equipped with anti-condensation function and heating function, well avoiding caking or deterioration when chemical powder is damp.
