Algae growth and photosynthesis can be inhibited in high-rate algae ponds (HRAP) in cold climates. This study evaluated the feasibility and importance of polyester fiber strips (PFS) that can be applied to HRAP as growing sites for algae survival, thus enhancing HRAP performance. The results indicated that 42.0±2.0% TN, 86.0±1.0% TP and 99.0±1.0% DCOD were reduced in HRAP with high PFS amounts, which outperformed HRAP with low PFS amounts and was significantly higher than control. The positive role of PFS on algae biomass production could effectively remove organics and nutrient from wastewater.
