This work is aimed at developing a design of a wastewater treatment plant to treat wastewater released from the Campus of the University of San Marcos in Lima - Perú. An anaerobic treatment of sewage has been designad to treat a load of 1.00 L/s of wastewater, containing a DBO5 of 220 mg/L. The required biorreactor has a capacity of 10.8 m3 , wich will operate at high yield compared to the standard processes of treatment. lt has been demonstrated that this process is economically and technically feasible, and the total cost of implementing, this project has been calculated in US$ 45 000, using locally available corrosion resistant material.

This work has the goal of designing a system to treat solid municipal wastes by recycling and final disposition in a sanitary filling field. Studies of handling solid wastes in the northem part of Lima, determine a rate of treatment of 800 TM/day. The filling field will be located near the Pan American high way, around the 38,700 Km in the district of Puente Piedra, taking around 100 hectares of field. Studies on climatological, geophysical, geodinamic and social impacts, determine that the environmental impact on the ecosystem will be minimal. Finally, the useful lile of the facility is estimated in 45 year at a total final deposition cost of US$2,60 /TM.

It has been developed a process of integration of fermentation systems of organical solid waste (OSW) in facilities of the «La Vizcacha» filling field, Puente Piedra District-Lima. We are obtained 225 mL ethanol and 0,008 5 kWh per kilogramm of urban solid waste.

In this work we present the design of a Process for the treatment of the urban salid wastes (USW) produced in the northern part of Lima. The plant will be installed in the district of Puente Piedra, region of Lima. The treatment capacily is of 1500 TM/day and ethanol, methane and diesel 2 has been produced of added value, also a higher reduction is achieved to 80% in volume of USW destination at present to the final disposition in the sanitarias fillings fields of Zapallal and The Vizcacha. The impact of the implementation ol this process will be positive so much in the technological, economic and environmental aspects.

En este trabajo se propone un proceso para el tratamiento de los residuos sólidos urbanos (RSU) generados en el cono norte de Lima. La planta se instalará en el distrito de Puente Piedra, región de Lima. La capacidad de tratamiento es de 1500 TM/dia y se produce etanol, metano y diesel 2 como productos de valor agregado, asimismo se logra una reducción superior al 80% en volumen de RSU destinados actualmente a la disposición final en los rellenos sanitarios de Zapallal y La Vizcacha. El impacto de la implementación de este proceso será positivo tanto en los aspectos tecnológico, económico y ambiental.

This work aims to simulate a bioreactor to produce ethanol from glucose using immobilized cells . First, we have proceeded to statistically evaluate the proposed kinetic models , from which we selected the model Aiba , Shoda and Nagathani [18 ] as the most appropriate model . Second, the values ​​of the simulated fermentation have been validated by comparing the results with experimental data and Mutharasan Gencer [17 ] . Finally , the yield of ethanol production was simulated by considering a bioreactor of PFR type . The solution of the equations of material balance was done using Runge Kutta algorithm in Mathcad 7P IV . Comparison of simulated and experimental Mutharasan Gencer sample values ​​appropriate arrangement .
