The dosage and dosage method of polyanionic cellulose PAC will vary according to the specific water treatment conditions. You can refer to the following common dosage and dosage methods:

1. Dosage: Generally speaking, the dosage of PAC is related to factors such as water turbidity, pH value, alkalinity, and water temperature. Under normal circumstances, the dosage of PAC is 0.1-10mg/L, and the specific dosage needs to be adjusted according to the actual situation.

2. Adding method: There are many ways to add PAC, the common ones are as follows:

    (1) Pre-adding method: Add PAC to the coagulation tank or reaction tank to interact with suspended solids and colloidal particles in the water to form large particles, which facilitates subsequent processing.

    (2) Post-adding method: Add PAC to the sedimentation tank or filter to interact with suspended solids and colloidal particles in the water to promote sedimentation or filtration.

    (3) Mixing and adding method: Mix PAC with other water treatment agents and then add them. If mixed with iron salt, the coagulation effect can be improved.

    (4) Direct addition method: PAC is added directly to the water and interacts with suspended solids and colloidal particles in the water to form large particles, which is convenient for subsequent processing.

It should be noted that the dosage method and dosage of PAC need to be selected and adjusted according to the specific water quality conditions and treatment requirements to achieve the best treatment effect.
