Abstract
The present disclosure relates to a multi-effect desalination apparatus by partially dosing acids into only evaporators corresponding to a relatively high temperature part, while dosing a polymer-based anti-scalant into all the evaporators, to minimize a risk of a scale and corrosion with maximizing a top brine temperature of desalination facility, and a desalination method using the same.
