With the increase in population, pollution, and water crisis, managing water resources becomes a high priority. This study was conducted to manage water resources and to investigate the performance of two microalgae biofilters, i.e. Chaetoceros(sp( and Chlorella, in the complementary treatment of municipal wastewater in the West Ahvaz Wastewater Treatment Plant. The phytoremediation of microalgae species was compared in biofilters at 0, 24, 72, 48, 100, and 150-hour retention time. Analysis of the results was done using SPSS software using one-way ANOVA and LSD post hoc tests. Multivariate covariance analysis (MANCOVA) was used on the mean results of the effects of Chlorella and Chaetoceros(sp( microalgae, and one-sample t-test was used to compare the means of indicators with the standard values. The results of multivariate covariance analysis to investigate the difference between the mean effects of Chlorella and Chaetoceros(sp( microalgae in time periods and groups of microalgae showed that the differences between the means of all indicators measured in time periods were significant (p<0.05) and the performance of microalgae biofilters in removing and reducing the parameters of COD, BOD, TSS, turbidity, iron, lead, mercury, phosphate, nitrite, nitrate, total and faecal coliforms for Chlorella and Chaetoceros(sp( microalgae were (83%, 81%), (81%, 79%), (77%, 65%), (73%, 82%), (83%, 98%), (91%, 92%), (86%, 96%), (78%, 67% ), (53%, 70%), (62%, 68%), (91%, 95%) and (89%, 96%), respectively. Moreover, the results showed that the final concentration of the studied parameters in the output of the biofilters was in accordance with the standard of the Environmental Protection Organization. Since the performance of the biofilters was favorable and close to each other, both types of microalgae biofilters were introduced as efficient biofilters and microalgae in the complementary treatment of urban wastewater, while the Chlorella biofilter removed physicochemical pollution and heavy metals and the Chaetoceros(sp( biofilter removed microbial load more efficiently.
