INEXA designs, supplies and assembles a wastewater treatment plant, with a treatment capacity of 20 m3 / day once a month at La Gomera Airport. The wastewater originates from carrying out firefighting practices at La Gomera Airport, in a raft with approximately 10,000 liters of water and with 100-300 liters of fuel (diesel and gasoline or kerosene). The tests consist of combusting the fuel and then using the corresponding extinguishing equipment using approximately 10,000 liters of water for extinction and a biodegradable foam concentrate for extinction (Aguafil AF-6). The test is carried out once a month. In total, approximately 20 m3 of residual water are generated, after being treated in the treatment plant, half will be discharged into a public channel and the other half will serve to fill the water storage tank, with 10 m3 of capacity.
