Abstract

Phytoremediation was known as an alternative technology in treating various type of wastewater. This application has been used worldwide and proven effective. Water hyacinth (Eichhornia crassipes) was used as the phytoremediation plant in treating PETRONAS Fertilizer Kedah Wastewater Treatment Plant effluent. The objectives of this project were to study the effectiveness and ability of phytoremediation method in treating fertilizer wastewater at three different detention time of 2, 4 and 6 days and to evaluate the effect of fertilizer wastewater in the growth of water hyacinth. Two reactor tanks each with a dimension 40 em width, 90 em length and 25 em height were prepared and set up at the UTP Sewage Treatment Plant. Both reactors were divided into three compartments (Compartment I, Compartment 2 and Compartment 3). Each compartment was 40 em x 30 em x 20 em. Water hyacinth was planted in the Wetland Tank with nine water hyacinths (three water hyacinths each compartment) while another tank without any plant acts as the Control Tank. Influent was pumped from the influent tank into the both reactor with fixed flow rate 12 Llday. Influent and effluents from each compartment were analyzed for Nitrate, Nitrite, Ammonia, Phosphorus and Chemical Oxygen Demand (COD). The results showed that water hyacinth was able to remove 79% of COD, 94% of Ammonia, 55% of Nitrate, 45% of Phosphorus. Water hyacinth also shown that it cans double its population in wastewater condition after the fortnights. This study concluded that water hyacinth was capable to remove the nutrient and COD from the fertilizer wastewater and growth perfectly in that condition.
