A brief description of the institution's water-related behavior change initiatives:
A brief description of the institution's water recovery and reuse initiatives:
CEM Campus uses treated wastewater for irrigation in the WWTP, with an average flow of 0.115 l / s and destination are the green areas of the preparation. - Discharges of wastewater to be treated from inside the Emerald Prepa generally toilets and dining. Arriving at the WWTP to solids separator. There are separate large solids such as rags, nylon, wood etc.. - The low water discharged by gravity to a lift station. - Subsequently by means of a submersible pump sends the water to the anaerobic reactor. This is where Anaerobic digestion of organic products, transforming them into simpler products, thus initiating the removal of organic matter. 1. Anaerobic reactor water passes by gravity to the aerobic reactor number 1. - RA # 1, follow the water by gravity to the RA # 2. - RA # 2, the water mixed with activated sludge reaches into the clarifier tank by gravity, where the clarified water is obtained at the top of the sludge tank and settle at the bottom of the tank and are returned to the RA # 1. - Passes water obtained an acrylic box where it is disinfected with sodium hypochlorite tablets. Downloading to a contact tank. - Contact tank the water is sent through a centrifugal pump to a deep bed filter where fine solids are separated from the water using sand filters. - The water, disinfected and filtered, is discharged into a storage tank and treated water is sent through a centrifugal pump to the irrigation of green areas on campus.
