Automatic Dosing Device

1.Main usage
    PDU automatic dosing device is widely used in auxiliary equipment of municipal water treatment and water sludge treatment; continuous and efficient completion of the polymer compounding and mixing to obtain homogeneous active polymer solution.

2.Working principle

    The device applies a jet mixer, using high-speed hydraulic to bre -ak up the drug or powder and increase the fineness, improve conta -ct of water and pharmaceutical or particulates, permeate area, red -uce the time of dissolution; the equipment uses three slots overflow combination: preparing, aging and dosing; through the solution’s specific gravity difference, caused by gravity and solubility, automatically separate the dissolved and undissolved; and then , by stirring of low-speed stirrer to improve the evenness of the solution.
