Abstract

Aquaculture produces considerable quantities of organic matter, ammonia, and phosphorus during cultivation processes. These wastes must be discarded from the fish pond and treated before discharged into receiving waters to prevent toxicity to the aquatic life and worsening of the water quality. Aquaculture waste which is left without properly treated will cause deterioration to the water quality standards inside the pond or receiving water. The water may no longer be suitable for the aquatic life or any beneficial use. The polysulfone (PSF) membranes were developed via dry-wet phase inversion technique with various polymer concentrations (19%, 21% and 23%) and immersed in different post treatment medium (methanol, ethanol and propanol) were analyzed to verify the potential for treating aquaculture wastewater. The PSF 21% in ethanol post treatment medium showed the highest rejection of ammonia with an average of 90% removal. The findings obtained indicated that membrane technology has a high potential for aquaculture wastewater treatment and helps to elevate aquaculture production quality.
