New Wetland Systems Purify Wastewater with Impressive Efficiency Rates!
Constructed wetland systems combining horizontal and vertical flow beds effectively purify wastewater from septic tanks. The systems showed stable removal rates for pollutants like COD, BOD5, TP, TN, and SS, with average removal rates exceeding 72%, 80%, 83%, 33%, and 60% respectively. Plant-based systems were more effective in removing pollutants compared to systems without plants.
