Abstract

The article represents a contribution that constitutes an improvement to environmental problems, in one of the most important current areas such as the conservation of water resources, which is one of the resources most affected by human and industrial actions. The study makes a design proposal for a wastewater treatment plant for the Tekunal restaurant, located in Lake Coatepeque, between the municipalities of Santa Ana and El Congo, in the department of Santa Ana in El Salvador.
A sampling of physicochemical and biological parameters of the water produced in the restaurant was carried out, as well as a review of the facilities of the place, through which it was possible to determine that the necessary conditions for the treatment of the water did not exist. With the laboratory results, the appropriate treatment was selected according to the capacity of clients, availability of resources and land that said restaurant has. In addition, a calculation report and the treatment train diagram were prepared, which will have preliminary, primary, secondary and tertiary treatment; providing as the best option the anaerobic treatment combined with the wetland, and the management of sludge by an external company, so as not to affect and inconvenience the users of the restaurant with possible bad smells.
