Abstract

Phytoplankton are at the base of the entire aquatic food chain. Their main applications are related to nutrition in aquaculture but they can absorbation nutrient wastewater and use them for their growth. Therefore culture of phytoplankton CHLORELLA VULGARIS with use from URBAN WASTEWATER at summer 1387 in Bandar Abbas treatment plant lab was investigated that we essayed moreover reduce of production cost, nutrient absorbation efficiency and settlement effect it. CHLORELLA VULGARIS with some density in different condition of wastewater (20, 40, 60, 80 and 100%) for the study on growth and three initial density, (‘high density’ 2×106 cells/ ml, ‘medium’ 1 × 106 cells/ml and ‘low’ 5 × 105 cells/ ml), were applied to primarily treated wastewater. The cell number increased gradually in the fourteen days and the rates of increase in 80 and 100% were more than other cultures. At the end of the 14 days study, over 80% of NO-3-N, 56% NO-2-N and 80% PO43--P were removed from wastewater in all cultures except the low density one. These results indicated that the efficiency of reducing wastewater nutrients by an phytoplankton system was directly related to the physiological activity and growth of the Chlorella cells which in turn were affected by the initial density. The high density culture seemed to be more beneficial as this treatment achieved satisfactory growth and NUTRIENT REMOVAL within 10 days instead of 14.
