The present investigation was to evaluate the behavior of two constructed wetlands in series with Phragmites australis for the treatment of domestic sewage. The wastewater source was captured drainage network of the Universidad Nacional Agraria La Molina. The wastewater was conducted by pipes to a sedimentation tank and cylinders and subsequently distributed to two reservoirs installed in series planted with Phragmites australis : A Horizontal followed a vertical marsh swamp. The porous medium marsh consisted of gravel and sand substrates . The marshes were operating with subsurface flow under conditions of continuous power . Performance monitoring of the treatment system was conducted during the months of November 2000 and January 2001, with weekly sampling . In analyzing the behavior of TSS and BOD5 in the horizontal marsh A removal of 97.2 % and 79.6 % were obtained. The horizontal sw...

Projections made by scientists on the water situation point to Peru as one of the regions most threatened by the scarcity of water resources by 2025. Droughts in various regions, the progressive loss of glaciers, contamination of the coastal basins , the overexploitation of water resources, the irresponsible use of the water resource due to poor irrigation practices, the increasing demand for water in densely populated cities, are problems that are affecting today in those places in Peru where the water resource scarce. The measures to counter water scarcity will depend a lot on the right decisions made by the State and the rulers. Some experiences developed in the State of Israel can be taken into consideration for water management in Peru. The State of Israel planned and carried out intensive long-term Research and Development efforts to integrate wastewater into the country's water re...

Electrocoagulation is frequently studied considering only the current or current density as a determining parameter when looking for the optimal conditions of wastewater treatment; however, these are correlated to the charge loading parameter that regulates the dose of metal to be dissolved. Due to this, the present study incorporates the charge loading to find the optimal conditions of treatment by electrocoagulation to the effluents of a dairy industry, “La Planta Piloto de Leche” of Universidad Nacional Agraria La Molina, taking as a variable response to the removal of turbidity. Work has been done in batch on prototypes of 2.2 liters of effective capacity. The aluminum and iron electrodes, acting as anode and cathode respectively, were the best materials for the treatment, in addition, the highest turbidity removal was achieved at a pH of 8 and a charge flow of 5.65 F/m3, achieve...
