Clarification of the water of wetlands using a mixture of natural coagulants

摘要

The purpose of this investigation was to evaluate the coagulant power of 5 natural combinations to clarify the water of a wetland.The clarification process was simulated with the jar test and a rapid agitation at 120 rpm was established for this test for 1 minute, slow agitation at 30 rpm for 20 minutes and sedimentation for 15 minutes.For the natural combinations, a ratio of 90-10, 80-20, 70-30, 60-40, and 50-50 yucca -seeds of Moringa oleifera was determined.After the process, the turbidity of the water was compared with a control sample.It was determined that the best results were obtained with treatment 2, 4 and 5 that removed the turbidity of the water from the wetland in 89.7%,93.0 and 93.4% and 93.4% respectively.
