Engineered column treatment of greywater using raw and pyrolyzed coconut husk powder

Reclaimed water from wastewater has become a prominent source option to manage scarcity. This study explores the potential of coconut husk biomass, common waste material in Ghana, as valuable low-cost resource for greywater treatment. Engineered column treatment was applied investigate influence pyrolysis and biochar properties biomass on Coconut pyrolyzed at 600°C characterized using SEM, FTIR, XRD. Three engineered columns with 1) raw powder (RCHP), 2) charred (CCHP), 3) sand-gravel filters (control setup) were used. A hydrostatic head throughput 8.0 ml/min hydraulic retention time 45 min maintained columns. The SEM image suggested an increased surface area pores due biomass. RCHP CCHP contributed 63% 95% turbidity removal, respectively. Experimental results showed high removal efficiencies 71% COD CCHP. nitrate efficiency 78.93%, 88.38%, 28.65% observed RCHP, CCHP, control log faecal coliform by two orders magnitude higher than RCHP. Faecal total 2.87 units Significant differences between p < 0.05 electrical conductivity dissolved solids effluents. promising Pyrolyzed is adsorbent applicable
