Studies on the Integration of Nanofiltration and Soil Treatment for Municipal Effluent Reclamation as a Groundwater Supplement
Water shortage leads to increasing attention to artificial groundwater recharge by reclaimed water. An injection well is the most common recharge approach. In this paper, a new kind of integrated technology—short‐term vadose soil treatment followed by nanofiltration—is recommended as pretreatment for artificial groundwater recharge by an injection well. Laboratory‐scale experiments demonstrate that the short‐term vadose soil can remove approximately 30% of the total dissolved organic carbon (DOC) content and 40% of dissolved organic matter with a molecular weight less than 1 kDa. As a compensatory process of soil treatment, nanofiltration offers a favorable desalination and additional organics removal. The removal efficiencies for total dissolved solids and conductivity amount to 45 and 48%, respectively. The residual DOC in the final effluent is below 1.0 mg/L. In addition, short‐term vadose soil offers effective elimination of aromatic protein‐like and polysaccharide‐like substances, which are detected as components of the membrane foulant.
