ترجمة الملخص

This study was conducted in two wastewater treatment plants (WWTPs): Al-Harah WWTP and Al-Jenderia WWTP, in Latakia, Syria, where both sites utilisethe principle of secondary wastewater treatment. The aim of the study is to assess the feasibility of a tertiary treatment (nutrient removal) option in a wastewater matrix using Duckweed.At first, the Duckweed Lemna minor L.was planted in the firefighting and irrigation tank in Al-Harah WWTP in a rectangular tank (3m x 3m x 1.6m, LxWxH) between January 2014 and April 2014. The results demonstrated the ability of Duckweed to adapt and grow in the secondary treated wastewater in Al-Harah WWTP, with an average weekly increase in plant mass of (430)g/m2. Water temperature in the Duckweed planted tank varied between 13.8 °C and 27.3 °C, average pH was 7.3 and electrical conductivity was measured between 1408 μS/cm -1444 μS/cm.Due, to the particularity of firefighting and irrigation tank (continuous flow, small size), it was difficult to control flow and hydraulic retention time (HRT), subsequently led to move to work in Al-Jenderia WWTP, which was put into service later. The particularity of firefighting and irrigation tank in Al-Jenderia WWTP, with the dimensions of tank were (6.5L × 5.5W × 1.75H) m gave the feasibility to control the flow and hydraulic retention time. The volume of the treated waterwas )63 m3(with HRT of 7 days, so the accurate results had obtained.The results of the performed analysis on Duckweed in Al-Jenderia WWTP, between October 2014 and November 2014 showed an average weekly increase in plant mass of (670)g/m2. Water temperature in the Duckweed planted tank varied between 17.2 °C and 20.9 °C, average pH was 7.48 and electric conductivity was between 1076 μS/cm -1106 μS/cm. The achieved removal efficiencies of ammonium, nitrate, phosphate, COD and BOD5in the Duckweed planted tank were 18.90%, 19.91%, 34.73%, 26.20% and 54.47%, respectively. Based on the above results a modification of the current process flow diagram of Al-Jenderia WWTP is proposed, where the Duckweed planted tank can be implemented as a tertiary treatment stage on the site, according to the appropriate dimensions of the design parameters of the WWTP.
