A zero-wastewater-discharge noncontact solar desalter for saline–alkali soil remediation and grain yield increase using brackish water

without wastewater discharge, sufficient to support 100% germination of wheat. Global wheat production is expected to increase by 1.09% based on the geographic information of wheat and soil. Our desalters provide guarantees for global food security with its environmental concepts of "zero wastewater discharge" and "soil remediation using brackish water".
