The aim of the research is to verify constructed wetlands as a sustainable solution for metal-laden wastewater treatment and to discover particular parameters for purification of industrial wastewater with different chemical composition. As an eco-friendly and economical method, bioremediation using plant, phytoremediation, is a promising strategy for removing, accumulating, or decomposing contaminants from water, soil, or sludge. The goal of the paper is to test the ability of metal removal from highly polluted batch systems and wastewater by Phragmites communis and Typha gracilis. Two experiments were carried out, firstly industrial wastewater was used. Typha gracilis and Phragmites communis were planted in two kinds of substrates. Half of the samples were planted in the combination of quartz sand and gravel. The second half of the samples grew in the ceramsite sand. The regular sampling of water (once per week) indicated a very quick removal of zinc ions from zinc-containing wastewater. Therefore, the model experiment followed the research. Samples of Phragmites communis were planted into the ceramsite and were watered by water containing zinc in concentrations ranging from 10 to 100 mg/L. Water was collected for analysis once per week. After four weeks, Zn concentration in all samples was below permissible pollution values for wastewater discharged from the selected industrial sector. After zinc removal from the water, all parts of the plant (root, leave, stem) and substrate were taken to analyze in order to gain information about the transfer and accumulation of zinc through the system. Inductively coupled plasma atomic emission spectroscopy as a suitable method for elements analyses of employed plants was used. Results have shown that Phragmites communis and Typha gracilis are suitable for zinc removal from wastewater.
