Microalgae are an alternative for wastewater treatment, as they have the capacity to
purify through phycoremediation. This research was performed at laboratory level to
reduce the contaminants in wastewater at IAM-Q Laboratory of the Department of
Environment, through the consortium microalgae Chlorella sp., and Scenedesmus sp.
The crops used for the treatment started with a cell density of 2.5x106 cell/mL
microalgea consortium, and 15 mL of Nitrofoska (3 mL/L), in plastic containers of
5 L capacity, 3 L of effluent was used pH 9 further control containing effluent
without the consortium was used, the experiment was performed in 5 replications and
maintained with constant aeration and illumination for 15 days. The growth of the
consortium microalgae was evaluated by cell count. The efficiency of removal of
contaminants from the effluent was determined, reporting maximum rates of 89.57%
for removal Chemical Oxygen Demand (DQO), 98.32% for Biochemical Oxygen
Demand (DBO5), 77.47% for total phosphorus, 99.18% for phenol, 89.8% for
surfactants, 18.03% for sulfates, 99.66% for cyanides and 99.20% for sulfur. |
