Removal of inorganic nutrients from wastewaters by microalgae is an efficient and productive method, which provides oxygenation to water bodies and useful biomass for several industries. The aim of this investigation was to determinate the nitrate (N-NO3) and phosphate (PO4) removal capacity by free and immobilized cultures of native strains of Chlorella sp. (Chlorelaceae) and Chlamydomonas sp. (Chlamydomonadaceae) in municipal wastewaters. Removal experiments were performed in sterile wastewater effluents from the same plant during 10 days. Microalgae were immobilized in 4 % sodium alginate discs. Free Chlamydomonas sp. reported the maximum N-NO3 removal percentage (75.08 %) while free Chlorella sp. showed the highest PO4 removal (83.69 %). Most of the cultures removed more than 50 % and 70 % of N-NO3 and PO4, respectively, during the first day. Immobilization affected negatively the nutrient removal, however, these values were higher or within high ranges of removal reported in previous studies. The results showed that both strains in free or immobilized cultures have the potential to be used for removal of inorganic nutrients in municipal wastewaters, especially for PO4 removal.
