5. How to Use

Wet dosing: First, make it up to 5%-10% solution with continuous and mechanical stir. Add to waste water after it completely mixed into suspension and turbid liquid until the pH reaches target value.

Dry dosing: Add it directly to the reaction pool, and control dosing through the pH value. This method is suitable for dealing with strong acidic sewage by adjusting its pH value to rough expected value with the product’s strong alkalinity.

 

6. Packing, Storage and transportation

Packed in 25 kg woven bag or paper bag.

Stored in dry,cool and ventilate place, it will keep good for 6 months. 


7.Production Process

The annual production capacity is 150,000 tons of hydrated lime, the product cycle is 36 hours, and the production time from raw materials to finished products is 30 hours. High-quality quicklime is selected as the raw material. During the production process, the water is automatically metered and added to avoid artificial errors. The advanced digestion system is designed to fully Stirring, no dead spots in the reaction, the unique secondary reaction of the aging fermentation tank for 24 hours, so that the original excess water and heat are lost in the circulating air, and at the same time water vapor is emitted to the residual quicklime to react with it to ensure the completion of the reaction, and then use reliable Mill and air separation equipment to ensure that the product can reach more than 325 mesh.
