EVALUACIÓN A ESCALA LABORATORIO DEL SISTEMA “ELECTROCOAGULACIÓN” COMO PROPUESTA PARA LA REMOCIÓN DE NITRÓGENO TOTAL Y FÓSFORO TOTAL EN EL TRATAMIENTO TERCIARIO DE AGUAS RESIDUALES DE ORIGEN DOMÉSTICO

Abstract

The article on tertiary wastewater treatment involves the design, construction and evaluation laboratory scale electrocoagulation unit, determining design parameters, such as dimensions, thickness of the plates, optimum current and voltage, once the unit is built taking samples of wastewater from secondary clarifier treatment plant of the colony Aurora II, eight replications were performed to assess the percentage of each macronutrient removal of nitrogen and phosphorus. The evaluation was done for a retention time of one hour unit, removals were achieved for the 27% nitrogen and 82.5% for phosphorous. The unit has a capacity of 20 liters, its lifetime is estimated at eight years and the cost per cubic meter of treated wastewater is Q28.23 ($ 3.50).
