Microalgae cultivation has gained tremendous attention in recent years due to its great potential in green biofuel production and wastewater treatment application. Membrane technology is a great solution in separating the microalgae biomass while producing high quality of permeate for recycling. The main objective of this study was to investigate the filtration performance of Ag/GO-PVDF (silver/graphene oxide-polyvinylidene fluoride) membrane in an algalmembrane photoreactor (A-MPR) by benchmarking with a commercial PVDF (com-PVDF) membrane. In this study

Chlorella vulgaris

microalgae was cultivated in synthetic wastewater in an A-MPR for ammoniacal-nitrogen and phosphorus recovery and the wastewater was further filtered using Ag/GO-PVDF and com-PVDF membranes to obtain high quality water. Spectrophotometer was used to analyze the chemical oxidation demand (COD)

ammoniacal nitrogen (NH

). The concentration of proteins and carbohydrates was measured using Bradford method and phenol-sulfuric acid method

respectively. The COD of the synthetic wastewater was reduced from (180.5 ±5.6) ppm to (82 ±2.6) ppm

due to nutrient uptake by microalgae. Then

the Ag/GO-PVDF membrane was used to further purify the microalgae cultivated wastewater

resulting in a low COD permeate of (31 ±4.6) ppm. The high removal rate of proteins (100%) and carbohydrates (86.6%) as the major foulant in microalgae filtration

with low membrane fouling propensity of Ag/GO-PVDF membrane is advantageous for the sustainable development of the microalgae production. Hence

the integrated A-MPR system is highly recommended as a promising approach for microalgae cultivation and wastewater polishing treatment.
