Nutrient removal from agricultural run-off in demonstrative full scale tubular photobioreactors for microalgae growth

[Display omitted] •Three full scale tubular photobioreactors used for microalgae growth removed nutrients from agricultural run-off and treated domestic wastewater.•Nitrogen removal efficiency was 65%, with values of around 90% in summer and 50% in winter. Phosphorus removal efficiency was greater t...
