Factors Affecting the Coagulation Effect of Liquid Aluminum Sulfate

Liquid aluminum sulfate in a certain conditions can be coagulation, the impact of its coagulation effect of what factors? Take a look at it

It is generally believed that the factors that affect the coagulation of liquid aluminum sulfate are water temperature, suspended solids concentration in water, pH value, coagulant dosage and so on. Water temperature is too low, colloidal Brownian movement slows, hydration increased, coagulant hydrolysis is slow, so the water temperature is generally 20 ~ 30 ℃ is appropriate. The experimental conditions for the water temperature of 25 ~ 30 ℃, in line with the most appropriate temperature requirements. While the concentration of suspended solids in water is low, the particle collision rate is greatly reduced, the coagulation effect is poor; but the concentration is high, the required coagulation dose increases. pH value affects the presence and surface properties of pollutants, but also affects the hydrolysis equilibrium of coagulants and the morphology and time of product existence. Leachate contains a high degree of bicarbonate alkalinity, the pH has a certain buffer effect.

The results show that the weakly alkaline leachate can achieve better experimental results without acid and alkali regulation. The dosage of liquid aluminum sulphate is related to the type and concentration of microparticles in water, and is also related to the variety of liquid aluminum sulphate, the dosage method and the medium condition.

Here, I believe we have a liquid aluminum sulfate has a general understanding of the bar
