Abstract

In this work, an innovative design of integrated photobioelectrochemcial system (IPB) and an algal harvesting method based on polyester-mesh membrane (MM) were investigated. The algal growth/harvesting period of 6 days led to the highest surface biomass productivity (SBP) of 0.88 g m⁻² day⁻¹ and the highest energy generation of 0.157 ± 0.001 kJ day⁻¹. The harvesting frequency of 3 times in an operational cycle (with three pieces of MM) enhanced the SBP to 1.14 g m⁻² day⁻¹. The catholyte recirculation for catholyte mixing resulted in a positive net energy production (NEP) of 0.227 ± 0.025 kJ day⁻¹. Those results have demonstrated the benefits of both using mesh membrane and the new reactor design for algal collection with positive effects on improving IPB performance.
