Abstract
The lack of wastewater treatment in Honduras is a problem that affects the entire country, even the most important cities such as San Pedro Sula. It has been found that this city does not have water treatment plants, and its rivers are polluted. The Blanco River is one of them, which is reported to be destroyed by the contamination present in the water flowing through it.The electrocoagulation method is a tool used to treat contaminants in water. The purpose of the research is to demonstrate the most efficient way to use the electrocoagulation method for the decontamination of the Rio Blanco. To do so, the variables of voltage and time at different levels were taken into consideration to check the optimal combination of these variables and to obtain a complete removal of total coliforms. The turbidity indexes found in each of the tests, electrode consumption and energy consumption were also calculated. The levels for voltage were 10 V, 15 V, 20 V and 25 V; on the other hand, the levels for time were 1 min, 5 min, 10 min and 15 min. It was decided to apply a full factorial design to visualize the relationship of the factors and the best combination of these.Once the design was applied, it was concluded that the best combination of voltage and time to apply in the electrocoagulation method is 15 V for 15 min, which ensures a complete removal of total coliforms with an energy consumption of 0.25 kWh/m^3. In water turbidity, the results showed fluctuations in the indices of the samples taken, so it is not considered a determining factor in the measurement of water contamination. On the other hand, the electrode consumption before and after each run was calculated; these did not present significant changes, so electrode consumption was minimal.
