| The applicability of filamentous periphyton (FP) to control of eutrophication and organic pollution was scrutinized in a eutrophic lake (Paldang) and a hypertrophic stream (Kyeongan). Growth rates of FP were highest at water velocity about 10 cm/s and net media with 4 mm mesh size, and increased with the phosphorus concentration of influent. When phosphate $(PO_4-P)$ concentration of lake water was in the range of $0.025{sim}0.075$ mgP/L, and water velocity was in the range of $5{sim}15$ cm/s, FP showed net productivity of $74{sim}125;mgChl-{alpha};m^{-2}d^{-1}$; specific growth rate of $0.42{sim}0.46$/d; phosphorus removal rate of $19{sim}103;mgPm^{-2}hr^{-1}$; specific removal rate of $62{sim}196;mgPgChl-{alpha}^{-1}hy^{-1}$. Phosphorus removal rates increased with phosphorus concentration of influent and water velocity. Aveyage removal efficiency of phosphorus was about 45% in the normal growth period. In the FP channel system at the hypertrophic stream, the maximum standing crop of FP was over 1,200 $mgChl-{alpha}/m^2$, and the net productivity was about 20 $gDWm^{-2}d^{-1};and;83;mgChl-{alpha}m^{-2}d^{-l}$, and specific growth rate was 0.36/d. In the normal growth condition, FP showed high oxygen production rate of $7.7;gO_2m^{-2}hr^{-1}$. Removal rate was $4.4;gO_2m^{-2}hr^{-1};for;BOD_5;;1.7;gNm^{-2}hr^{-1}$ for total nitrogen (TN); $278;mgPm^{-2}hr^{-1}$ for total phosphorus (TP); $85;mgPm^{-2}hr^{-1};for;PO_4-P$, respectively, Specific phosphorus removal rate was $1,252{mu}gPgDW^{-1}hr^{-1}$ in TP and $376{mu}gPgDW^{-1}hr^{-1};in;PO_4-P$. Phosphorus removal rate increased with standing crops of FP. The N/P ratio of effluent in the FP system was high compared with that of influent. It seemed to be attributed to the phosphorus limitation for the growth of FP. |
