The present paper describes pilot plant development of a novel process enabling increase of water recovery in brackish water desalination without using any chemicals. This is achieved by precipitating the scaling salts of a carbonate-rich concentrate by increasing the pH through air stripping of CO2

Many scaling species such as CaCO3, Mg(OH)2 and Ca3(PO4)2 present in brackish and wastewater feeds can be removed by precipitation processes induced by raising the pH level of the raw water. These processes require dosage of alkaline chemicals such as NaOH, lime or magnesia. An interesting possibili

Desalination of brackish water containing silica at high recovery levels leads to a rapid flux decline, due to the precipitation of a colloidal solution consisting of polymerized silica nano-particles. The critical flux (CF) phenomenon postulates that there is a certain permeate flux level below whi
