Water is the basic element that we use in our daily life. The failure of proper wastewater treatment from the plant to the river stream is one of major factors for the degradation of water quality. Phytoremediation system was being started over 10 years ago and is now rapidly developing. The treatment of wastewater using specific aquatic plants has been proven to be efficient on-site. This technology removes harmful chemicals from the ground when the roots of the plants absorb water and nutrients from polluted soil, streams and groundwater. Aeration is a part of the wastewater treatment process, this process aims to remove and break several elements in wastewater. Aeration process provides oxygen to the water, increasing dissolved oxygen content to increase the oxidization of pollutants. Two samples of wastewater were taken from the aeration zone and the samples were being tested with parameters like BOD, COD and Total Suspended Solids. These parameters would then determine the standard of the water being released to the river after going through the aeration zone in an integrated phytogreen system. There were two methods of experiments being conducted to test these water parameters which were the in-situ and ex-situ experiments according to The Examination of Water and Wastewater (APHA; AWWA; WEF, 2005). 5.2.1. Aeration zone has been successful in lowering the value of Chemical Oxygen Demand and Biochemical Oxygen Demand. Aeration zone has lowered 97% of BOD and 96% of COD in this study. The overall removal efficiency for BOD and COD were 98.1% and 97.6% respectively. Suspended Solids has been decreased at 85% through the aeration zone, and 90% after the overall process. The concentration of suspended solids in this integrated system was in Standard A. As a conclusion, aeration zone has enhanced several parts of the phytogreen integrated system.
