In the present work, a prototype based on nanoadsorbents for the removal of lead species II from Lake Chinchaycocha is designed and built. A phased or staged design methodology is used in which the initial input parameters refer to the performance of the nanoadsorbent in an adsorption column, field conditions such as solar availability and navigation. Thus, in the prototype three systems are identified: the hydraulic conduction network, the autonomous photovoltaic system and the flotation system. The design process begins with nanoadsorbent column tests under field conditions in the area of operation. In this experience, the breakthrough curve is determined and thus the filter performance is characterized. With these results, scaled operating conditions are simulated and the amount of adsorbent needed is determined. The dimensions of the decontamination network are selected in such a way that the hydraulic pump can support the manometric height generated in the filters. Then the autonomous photovoltaic system necessary to sustain the daily energy demanded by the electrical devices, mainly by the pumping system, is sized. These devices are packaged in cubicles for installation. With all the dimensioned components, the floating system is designed in such a way that it gives the prototype buoyancy and stability during navigation. Finally, the necessary materials were identified and simple steps are established for the installation of the prototype. Using the procedure outlined and knowing the principle of operation of the systems installed in the prototype, the main aspects to be controlled in its design are identified: the level of adsorbent load in the column and the total manometric height in the hydraulic conduction network. In the case of the autonomous photovoltaic system, conditions were established that guarantee an optimal operation and long durability of the electrical components due to the fact that in its dimensioning a safety factor was used for the calculations, thus allowing to cover the energy demand for the photovoltaic generator and the energy storage. The flotation system was assembled from available and low-cost materials. The developed process, although it employs an intuitive method, however it guarantees to achieve the expected operating results. Finally, for the economic analysis, the designed prototype is considered as a drinking water supply to the nearest population, and the lowest sale price that guarantees profitability for the investment in the project is determined. The results indicate the need to establish the conditions for the service to be marketed since its commissioning requires a considerable initial investment. The determined sale price, on the other hand, is comparable to the value established by the market so that its insertion into it would not present any inconvenience. Among the main recommendations, we have to analyze the species present in the matrix of the lake to optimize the performance of the filter and to continue improving the process of synthesis of the nanoadsorbent, so that a lower manufacturing cost can be achieved and it will give the service greater competitiveness.
