Photosynthetic processes have emerged as an innovative biological platform capable of performing a cost-effective treatment of wastewater with a concomitant assimilation of nutrients into biomass. In this work, the performance of a purple phototrophic bacteria photobioreactor (PPB-PBR) coupled with a microalgae-bacteria photobioreactor (MB-PBR) was assessed during the treatment of PWW at an hydraulic retention time (HRT) of 12.2 (stage I) and 6.2 days (stages II–VI) and intensities of near-infrared radiation in the PPB-PBR of 30 W m−2 (stages I–II) and 114 W m−2 (stages III–IV). Maximum removal efficiencies of total dissolved organic carbon (TOC-RE) and total dissolved nitrogen (TN-RE) of 91% and 82%, respectively, were recorded at an HRT of 12.2 days. The decrease in HRT to 6.2 days reduced the TOC-RE and TN-RE in both photobioreactors, but the increase in near-infrared radiation enhanced TOC-RE in the PPB-PBR, contributing to a global carbon recovery of 67% via assimilation in the form of PPB biomass. PPB-PBR was highly efficient in carbon assimilation, while MB-PBR enhanced nitrogen and total suspended solids removals, with a contribution to TN-RE of 63% and a global decrease in TSS of 76%. The culture broth of PPB-PBR was dominated by Rhodopseudomonas sp. up to 54%, supported by the high HRT and the increase in near-infrared radiation, while the sequential MB-PBR favoured the dominance of Mychonastes homosphaera.
