HEAVY METALS AND CONTAMINATION PARAMETERS REMOVAL BY DIFFERENT PLANT FROM WASTEWATER IN HYBRID CONSTRUCTED WETLANDS

Abstract

Water is essential requirement for every living creature on our planet to grow and prosper. The progress expansion and increased population of Sulaimani city caused increased in water demand and need for reusing of waste water for irrigation. This study aims to remove some waste water heavy metals and parameters by root and shoot of Macrophytes in Hybrid Constructed wetlands (HCW). HCW are designed as (Vertical-Horizontal and Horizontal-Vertical) along with sand filtration implemented with two local Macrophytes (Typha angustifolia and phragmate australis). The plant root and shoot were analyzed in beginning and end of the study to determine the removal rate. The result shows increase in the mean concentration values of heavy metals and waste water parameters in root and shoo of both T. angustifolia and Ph. australis in HCW (H&V) and (V&H). Therefore, Macrophytes in HCW can be used to remove heavy metals and other parameters from waste water used for irrigation.
