The Industrial Wastewater Treatment Plant (Edari) of the La Campana industrial estate, in the metropolitan municipality of El Rosario, already treats a monthly volume of sewage equivalent to the capacity of one and a half Olympic swimming pools. The sanitation infrastructure purifies an average of 108 cubic meters daily, according to the latest operating report of a facility whose implementation has helped solve the historical problem of lack of capacity to treat sewage in the area. In fact, the La Campana Edari began its journey a little over two years ago, when it became the first treatment plant of its type launched in the Autonomous Community.
The mayor of El Rosario, Escolásico Gil, stressed yesterday the importance of “the companies in our industrial estate being able to discharge their wastewater with complete security of its treatment and purification, not as was happening previously, when it went directly to a well. the urbanization of Costanera through a totally illegal connection. The first mayor of the metropolitan municipality added in this regard that the El Rosario City Council is thus “an example that from the local level firm steps can be taken to benefit sustainability and purification.”
Besides, The Edari of the La Campana industrial estate consumes its own electrical energy, which is generated through a solar field made up of 250 photovoltaic modules with a power of 100 kilowatts (kW), which represents an electricity saving of 44% and stops emitting the equivalent of 96 tons of carbon dioxide each year. This industrial wastewater treatment plant treated between February and July of this year a total of 19,483 cubic meters of sewage, which is equivalent to 19.5 million liters and a wastewater volume of almost eight Olympic swimming pools. The monthly average is 3,247 cubic meters of treated industrial water and the daily average is 108 cubic meters, although it is prepared for a maximum of 250 cubic meters per day. Furthermore, in those six months the volume of sludge delivered to authorized managers amounts to 12.7 cubic meters.
The La Campana industrial estate is a “milestone”, they explain from the El Rosario City Council, as far as purification in industrial centers is concerned, and its Edari, together with its pumping station and the new treatment plant in the Costanera urbanization, solved the wastewater discharges into the sea that occurred at the beginning of 2020 thanks to a joint investment of more than three million euros.
The La Campana treatment plant covers around 280 companies located in the industrial area and consists of a pumping station located at the lowest point of this industrial center, from where the water is then raised to the treatment plant itself. The process followed in this purification system consists of the pretreatment of wastewater with a fine sieve, gritting and degreasing; rolling deposit; biological reactor; disinfection channel; sludge pumping; and a deodorization equipment with the capacity to treat 1,600 cubic meters of air per hour to prevent bad odors. The facility is completed with a control building where the offices, toilets, electrical room, sludge dehydration area, blowers, workshop and all other spaces and units necessary to carry out the activity are located.
