Post treatment of secondary wastewater effluent for irrigation purposes using Ulva lactuca algaeOla AlrawaghBackground: Due to the continuous population increase and so the quantities of produced wastewater and the failure of treatment plants in Gaza strip, huge quantities of raw or partially treated wastewater is discharged into the sea which increase the presence of the seaweeds like Ulva sp. The macroalgae of the genus Ulva can have applications in the wastewater treatment.Objective: To study the effectiveness of Ulva lactuca whole organism and powder in post treatment of secondary wastewater effluent for irrigation purposes.Materials and Methods: Each liter of wastewater was treated by powder and whole algae. Electrical conductivity (EC), power of hydrogen (pH), chloride ions and nitrate were measured for raw and treated secondary wastewater. Microbiological quality for both raw and treated secondary wastewater effluent were measured. The treated wastewater with the best results was used for irrigation of Arugula seeds (Eruca sativa) which were bought from JUMARSTM Company, as well as others were irrigated by medium salinity water (5000 mS), and by filter water, and some were fertilized with powder of algae.Results: The treated wastewater with whole algae and powder algae showed slight increase in EC, Cl-, pH and decrease in nitrate concentration. COD levels decreased after treatment with algae. Heavy metals analysis (Fe, Zn, Pb, Mn, Sr) showed decrease in concentration after algal treatment. Bacteria and fungi count in treated wastewater with algae decreased as well as Coliform bacteria and Salmonella and Shigella spp. Arugula plants samples which irrigated with algal treated wastewater and those that fertilized with powder of algae showed increase in average area of leaves, leaves number as well as average root lengthConclusion: Ulva lactuca whole and powder algae have a tangible impact in tertiary treatment of wastewater and reuse in irrigation, also the powder algae has a tangible impact as a biofertilizer. Keywords: Ulva lactuca, algae, wastewater treatment, Arugula
