A floating cover and baffle system used to vastly increase treatment effectiveness of wastewater treatment lagoons used to remove pollutants from water. The floating cover prevents direct sunlight penetration which prevents the growth of algae, while allowing air to flow between the cover and the surface of the lagoon to maximize oxygen transfer. The baffle system consist of several aerobic baffles and anaerobic baffles. The aerobic baffles are located perpendicular to the direction of flow of wastewater and directs the flow into the upper region of the lagoon which is where aerobic micro-organisms prevail and there is the most available oxygen. The baffles are also secured at a thirty degree angle with the bottom of the lagoon in order to minimizing solids settling and prevent the accumulation of solids in a concentrated area which can cause odor problems. The anaerobic baffles are very similar to the aerobic baffles except the flow is directed to the lower region of the lagoon which is where anaerobic micro-organisms prevail.
