Project description
The construction of the Wastewater Treatment Plant (WWTP) was carried out in the Chapultepec forest area, once the previous 50-year-old plant was demolished, it captures the sewage through collectors in the Lomas de Virreyes and Lomas de Chapultepec area. The project consists of a reactor composed of several structures such as the sieve, with four treatment phases: anaerobic reactor, anoxic reactor, aerated reactor and endogenous reactor whose structures are made of reinforced concrete and walls with a thickness of up to 80 cm and heights of up to 9.00 meters and molded in a monolithic way. Air is incorporated in several reactor processes through five stainless steel blower and pipe equipment; which were installed based on metal structure pendants; a membranes tank, that was constructed with a bottom slab, and reinforced concrete walls in a monolithic manner. This tank of membranes in its process of operation requires the inclusion of air, and for this a group of four blowers were installed. The air injection is done through carbon steel pipes. For the operation, an electrical substation with a capacity of 34 kva was built, based on footings, block walls and a reinforced concrete slab, as well as an administrative building, green areas, parking and roads.
