Abstract
The inhibitory effects of free ammonia (FA) on microalgae/cyanobacteria in wastewater-treating photobioreactors (PBR) can strongly reduce their treatment efficiency, increasing the operational costs and undermining the stability of the system. Although FA-promoting conditions (high pH, temperature and ammoniacal nitrogen concentration) are commonly met in outdoor PBRs, photosynthesis inhibition from FA has been scarcely explored and is rarely considered in microalgae-bacteria growth models. Two ...
