Abstract
The objective of this work was to chemically evaluate the solid liquid phases of swine biofertilizer separated by different flocculants. The experimental design was completely randomized, with five kinds of flocculants and five doses of each flocculant, with five repetitions. The separation was conducted through flocculation/decantation for an hour after the addition of each flocculent. The chemical characterization was done on the solid and liquid biofertilizer phases from the determination of the following elements: N, P, K, Ca, Mg, Cu, Zn, Fe and Mn. For the liquid phase, the purpose of decreasing macronutrients was achieved using the doses of 10 and 20 mL of the combination between the flocculants dolomitic limestone + calcium hydroxide, and micronutrients reduction occurred when the flocculants aluminum sulfate and calcium hydroxide + aluminum sulfate were used.Downloads
