There are two new validated low energy and low capex technologies for treating hyper saline water such as neutralized acid from lead acid recycling operations that could significantly help reduce water footprint and improve water discharge compliance. The first is “Dual Cavitation” which precipitates dissolved solids including sodium chloride and sodium sulfate from solution, producing clean water and solids for disposal. The second is “Electro Hydrodynamic Drying” which uses an electric field to atomize salty water into extremely small droplets which quickly evaporate in a hot air stream producing vapor and dried solids. The first method is appropriate if the client wishes to reuse the water. The second is ideal if the client wishes to eliminate water discharge. Both methods are zero liquid discharge.
