The aim of this
study was to evaluate the nutrient uptake capacity of an algal biofilm as a means to treat polluted water.
In addition, the study investigated the nutrient removal process. The algal biofilm was able to remove 99%
of phosphorus within 24 hours of P addition, with the PO4-P concentration in inflowing water ranging
from 3 to 10 mg L¡1. Different patterns of phosphorus and nitrogen removal were observed. Daily
quantity of removed NO3-N ranged from 2 to 25% and was highly dependent on solar irradiance. Precipitation
of phosphorus during the removal process was studied using X-ray diffraction analyses and was not
confirmed in the biofilm. The biofilm system we constructed has a high efficiency for phosphorus removal
and, therefore, has great potential for integration into wastewater treatment processes.Workplace Global Change Research Institute Contact Nikola Šviková, svikova.n@czechglobe.cz, Tel.: 511 192 268 Year of Publishing 2018
