Using molar ratios of the algae-based biofilm, it was also possible to derive a temperature correction coefficient from the biofilm productivity values in order to predict nitrogen and phosphorus uptake by the system. Rates of nitrogen and phosphorus uptake are reported in Table 3 as K N and K P respectively, and the temperature correction coefficients for nitrogen and phosphorus, Θ N and Θ P, are also reported in Table 3. At a known water temperature and concentration of organic carbon, the Θ N-values from Table 3 can be applied to the equation5\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {K}_{N, prediction}=0.723*{\theta_N}^{T_{water}-280} $$\end{document}KN,prediction=0.723*θNTwater−280to predict rate of nitrogen uptake (mg m-2 day-1), and the Θ P-values from Table 3 can be applied to the equation6\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$$ {K}_{P,\ prediction}=0.098*{\theta_P}^{T_{water}-280} $$\end{document}KP,prediction=0.098*θPTwater−280to predict rate of phosphorus uptake (mg m-2 day-1) by the biofilm.
