Product features: the product indicators meet the drinking water grade standard of gb15892-2020. It has the characteristics of fine powder, uniform particle, easy dissolution in water, good flocculation effect, high efficiency and stability of purification, low dosage and low cost.
Application: widely used in drinking water, urban water supply and industrial water purification.
Solid products need to be dissolved and diluted before being put into use. Users can determine the best dosage through testing and dispensing reagent concentration according to different water quality.
① Solid products are 2-20%.
② The dosage of solid products is 1-15 g / T,
The specific dosage shall be subject to flocculation test and experiment.
Packaging and storage：
The solid is packed in 25kg bags, with inner plastic film and outer plastic woven bag. The product shall be stored indoors in a dry, ventilated and cool place, and shall not be affected by moisture. It is strictly prohibited to store it with flammable, corrosive and toxic substances.
