Age of sludge: If the age of sludge is too long, the activity of microorganisms will be reduced, and a large amount of sludge will be produced, which will affect the thickening effect. Pre-treatment of sludge: Pre-treatment of sludge, such as acidification, alkalization, etc., can change the nature of sludge, affecting the thickening effect.
