Studies on the Pilot Scale Filtration System for Coir Wastewater Treatment

Pilot scale low cost system was carried out in the Coconut Research Station for treating coir industry wastewater using Vetiver zizanioides along with Vermiculite clay mineral. Wastewater collected from the two different sites were considered as two treatments. The reduction in pH, EC, BOD, COD, TDS and Polyphenols at both the treatments (T1 and T2) was observed. Major reduction was observed in the TDS content with the reduction percentage of 49.73% and 51.03% for T1 and T2 respectively. Likewise, reduction percentage of polyphenols in T1 and T2 were 4.76% and 4.9%, respectively. Hence, phytoremediation using vetiver was found to be a promising approach for remediation of coir industry wastewater.
