APPLICATION OF BIOFILMS IN REMOVAL OF HEAVY METALS FROM WASTEWATER IN STATIC CONDITION Ogbuagu Dike Henry, Nwachukwu Ikenna Ndubuisi, Ejike Onyinye Joy

Abstract

The aim of the research was to utilize biofilms as a model in ecotoxicology to remove selected heavy metals (Cd, Cu, Cr, Zn and Pb) from wastewater in a static condition. Biofilms were grown in three graded concentrations of the metal leachates (0.625, 0.417 and 0.250 %), harvested after 1, 2 and 3 weeks and analyzed for heavy metals. Mean accumulations peaked on Day 21, and of Cd ranged from 0.000 to 0.040 (mean = 0.00837 ± 0.002), Cu from 0.000 to 0.212 (meam = 0.03929 ± 0.012), Cr from 0.000 to 0.500 (mean = 0.05821 ± 0.021), Zn from 0.000 to 1.456 (mean = 0.31833 ± 0.109) and Pb from 0.000 to 0.099 (mean = 0.02129 ± 0.006) mg/g in resultant biofilm formations. Accumulation of the metals increased significantly with time [F(205.59) > Fcrit(3.95)] at the 95% confidence interval. Those of Pb was significantly higher in the 0.625% leachate mixture than control (Sig F = 0.034) at P < 0.05, even as those of Cd and Cu were slightly higher in the concentrations than control. Biofilm model removed small amounts of metals from wastewater stream in static condition.
