5. How to Use
Wet dosing: Firstly, make it up to 5%-10% solution and continuously mechanical stir. Add to waste water after it completely mixed into suspension & turbid liquid until the PH value come to target value
Dry dosing: add it directly to the reaction pool, control of its dosing through the ph value. This method is suitable for dealing with strong acidic sewage; adjust the ph value to rough though its strong alkalinity.
6. Packing, Storage and transportation
Packed with 25 kgs woven bag or paper bag.
Stored in dry ,cool and ventilate place, it will keep good for 6 months.
