| dc.description.abstract | In this study, the separation of water from fish farm water via forward osmosis was carried out. The membrane used in this study was cellulose triacetate (CTA) membrane. The effect of different draw solution concentrations (1.0 M, 1.5 M, and 2.0 M) and crossflow velocity of feed solution (10.0 GPH and 12.0 GPH) on the membrane performance were studied. The fouling phenomena of the membrane was evaluated based on pre-treat and untreated fish farm effluent. It was found that the water permeate flux increased when the draw solution concentration was increased due to higher osmotic pressure. The water permeate flux also found increased when the crossflow velocity was increased, where the highest water permeate flux was recorded at 7.48 ± 0.15 L/m2.hr. The rejection level of phosphate, nitrate and ammonia was found to be high at draw solution concentration of 1.0 M and feed solution crossflow velocity at 12.0 GPH. The fouling phenomena of the membrane is observed and analysed using scanning electron microscope (SEM) and energy dispersive X-ray (EDX). The fouling was found to be not severe for both filtered and unfiltered fish farm water. | en_US |
