Toxic wastewater treatability study by soil aquifer treatment (SAT) with adsorbent

Abstract

Soil aquifer treatment (SAT) is a most proficient innovation which depends on broad physical and biogeochemical forms in the underground water and aquifer for water quality change. In this investigation, the conveyance, quantitative changes and, in addition, the speciation qualities of heavy metals in various depths of soils of a 2-year worked laboratory-scale SAT are investigated. A greater part of the heavy metals in the energized secondary effluent are effectively caught by the consistent state worked SAT. Here, the removal efficiency of SAT with and without adsorbent is conveyed for parameters like pH, total dissolved solids, total solids, chloride, COD, TKN, potassium, phosphate, copper, zinc, nickel and hexavalent chromium. The investigations are completed by utilizing toxic wastewater and fluctuating adsorbents, for example, eucalyptus leaves, sawdust and mosambi peel (MP). Here, the soil types of clayey sand, inorganic silt with sand (MI SAND) and silty sand are utilized and their properties are resolved. To enhance the removal efficiency of SAT for expulsion of heavy metals, distinctive adsorbents and, in addition, different soil tests are utilized. In the light of investigation, the SAT system with adsorbent is more effective in treating toxic wastewater.
