Purification of Sewage Wastewater though Sand Column Filter for Lessening of Heavy Metals Accumulation in Lettuce, Carrot, and Cauliflower

Sewage wastewater is one of the richest sources mineral nutrients contributing toward plant growth and yield. However, accumulation heavy metals in edible parts vegetables fruits can be dangerous to life. The current research aimed evaluate performance a sand column filter for elimination from sewage applied selected vegetables. contents metals, i.e., Pb+2, Ni+2, Cu+2, Fe+2, were estimated higher untreated than treated water. number leaves, fresh dry weights roots, total biomass lettuce, carrot, cauliflower improved due irrigation unfiltered compared wastewater. curd diameter, curd, stem weight cauliflower, root length diameter carrot increased after with comparison was In present study, Cd+2 Cr+2 concentrations not affected by filtration process through filter. Conclusively, effective removal used irrigate agricultural land.
