        abstract = {The increasing contamination of water 
resources due to domestic and industrial activities 
necessitates the development of low-cost, sustainable 
methods for wastewater treatment. This study 
evaluates a multi-layered column filtration method 
employing natural adsorbents: wooden sawdust, acid
washed river sand, biochar from neem and tulsi leaves, 
and poplar bark ash. The column treated sewage 
wastewater, targeting specific pollutants through each 
layer. Water quality parameters like turbidity, pH, 
COD, BOD, and microbial load were assessed before 
and after treatment. Results demonstrated significant 
reductions, supporting this as a cost-effective, eco
friendly wastewater treatment solution.},
