| Summary: | Residential and Housing Research & Development Center (Puskim), Ministry of Work and Housing (PUPR) has developed a wastewater treatment plant (IPAL) biosorption system capable of reducing heavy metal lead (Pb) from domestic waste, to safe limits with the help of water plants that are heavy metal accumulators. This study aims to analyze the IPAL ability of the biosorption system in lowering Pb concentration in domestic wastewater and determining the effect of Pb concentration on plant biomass. Water samples were taken at three points of (IPAL), there are influent wastewater, biosorption units, and indicator pools. The concentration of Pb in water and plant part (root and canopy) is measured by destructive method. The concentration of Pb was analyzed by Atomic Absorption Spectrophotometry (AAS) -Flame, then analyzed further to determine the value of Pb removal efficiency of each unit of IPAL biosorption. Plant dry biomass is measured at the beginning and end of the day of observation. Water temperature and pH are measured using a digital pH meter with three repetitions. The results showed that Pb accumulated in both species, both jasmine and T. latifolia were able to accumulate Pb at the root with concentrations of 4.43 mg / g and 4.531 mg / g, respectively. The percentage of dry biomass of E. palaefolius decreased from 86.36% to 83.5%, but in T. latiolia increased from 79.57% to 86.06%, although the difference is not significant (p value<α). This is because T. latifolia is more resistant to heavy metal Pb than E. palaefolius. The rhizofiltration unit in IPAL biosorption has a better average removal efficiency value of Pb metal compared to the biosorption unit of 61.356% and 52.06%, respectively, although both units can decrease the average Pb concentration to 0.001 ppm in the waters so as to meet the quality standards of waste water. Pb concentration which reached 0.4135 ppm did not give significant effect to plant biomass. |
