The ,effect, of sulfate on effluent Al concentrations was studied in a laboratory study in treating Al‐bearing AMD treatment using NaOH (Zhao, Liang, Wang, Li, & Pu, 2018). It was found that, despite the reduction in soluble Al concentration, the presence of sulfate could actually increase the total effluent Al concentration due to the formation of small nonsettleable Al‐containing particles.

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.
