Note: the indexes of Fe, As, Pb, Cd, Hg, Cr, and insoluble substances listed in the liquid products in the table are calculated as 10% of AL2O3. When the content of AL2O3 is > 10%, the impurity indexes shall be calculated as 10% of AL2O3 products. |
Method of Use
Solid products should be dissolved and diluted before input. Users can confirm the best input volume by testing and preparing agent concentration based on different water quality.
● Solid product:2-20%.
● Solid product input volume:1-15g/t.
Specific input volume should be subject to flocculation tests and experiments.
Packing and Storage
Every 25Kg of solid products should be put in one bag with inner plastic film and outer plastic woven bag. Products should be stored in the dry, ventilated and cool place inside the door for fear of damp. Don't store them together with inflammable, corrosive and toxic goods.
