Apu Wood (Pistia stratiotes) as Phytoremediation Agent of Screen-printing Wastewater

Abstract. The screen-printing process produces wastewater like organic compounds that are difficult to degrade and heavy metals such as chromium, copper, manganese, lead, which toxic can accumulate in the human body through food chain. Phytoremediation is one method utilizes plants' ability reduce inorganic pollutants, including metals. Objective: This study aimed describe concentration of waste be tolerated by apu wood plants analyze effectiveness a metal remediator. Technology or Method: used this research combination filtration phytoremediation using Pb Cr,6+ preliminary test Cr6+ contained was carried out. Results: Apu lives thrives on wastewater, with an average 34 new individuals' tillers growth within 15 days. propagation produced total biomass 145 grams per reactor. remediator 13.65%, accumulated leaves 0.0911 mg/L. accumulation 0.6635 component during days treatment did not show positive effect removal because higher chromium element oxidation reaction occurred process.
