Menu Business Our work Drinkable Drinking water Drinking water The purification treatment begins with the determination (online) of the pH and turbidity of the water at the entrance of the Drinking Water Treatment Station (ETAP). Coagulant (poly aluminum chloride) is then metered in, which reacts with suspended solids, giving rise to a precipitate (floc). Subsequently, flocculant (polyDADMAC) is added , which favors the decantation process , forming more voluminous and heavier flocs as well as micro-sand that allows the formation of flocs with a higher specific weight, so we can increase the decantation speed. The process incorporates a hydrocyclone system, which allows the micro-sand to be recovered for continuous reuse in the process. After passing through the ripening chamber, the water reaches the lamellar decanters , at the outlet of which the already clarified water is obtained, on the one hand, and the sludge, which is led to a thickener for further treatment. Once the water has been decanted, it goes to the filtration stage , in this stage the water passes through a filter bed of siliceous sand and granular activated carbon, the solids in suspension of the water being retained in it, obtaining the Low turbidity water filter outlet. In addition to this retention, removal by adsorption of organic substances and therefore removal of odors and flavors will also take place. Finally, a final disinfection is carried out , by dosing chlorine to the filtered water, until reaching the established values of residual free chlorine at the plant exit. © 2018 MUNICIPAL MIXED COMPANY ABASTECIMIENTOS Y SERVICIOS DE CALPE, SA All rights reserved Contact Web map Dictionary Responsible consumption Contractor profile Hiring @Invoice PDF Frequent questions Sail happily Legal information Cookies policy We use our own and third-party cookies to facilitate navigation and obtain statistical information on the use of our visitors.
