The acid most commonly used is sulfuric acid and the most commonly base is lime [Ca(OH) 2]. When activated silica is added to water, it produces a stable solution that has a negative surface charge. The activated silica can unite with the positively charged aluminum or with iron flocs, resulting in a larger, denser floc that settles faster and enhances enmeshment.
