Abstract

It was studied the relationship among means alkalinity concentration as calcium carbonate, and the nitrification process in an aerated oxidation lagoon in batch and pilot scale (1,72 m3 as total volume and 1,46 m3 as effective one) working on a residual synthetic liquid, elaborated with base in sucrose, sulfate and ammonium phosphate. The results demonstrated that when being increased the initial alkalinity in the range from 120 to 360 mg CaCO3/dm3, the nitrification process efficiency increased significantly until the surroundings of the 86%, decreasing when being this with smaller and bigger values that said range. The dissolved oxygen concentration stayed around 4,3 mg/dm3, belonging together with the aerobic character of the microorganisms for nitrification (Nitrosomona and Nitrobacter). The initial concentration of total nitrogen in each one of the 14 processes batch was 38 mg/dm3 and the same one went down to minimum values around 4,56 mg/dm3.
