29/11/2015, · This is the precipitation of heavy metals from the solution. Through the manipulation of the wastewater pH (neutralizing the pH from very low or very high values), the neutralization process actually initiates the redox reaction process. In turn, the redox reactions initiate the precipitation process and subsequently the solidification process.
