TECNADIS METALCOAT “EASY-TO-CLEAN” IN WATER TREATMENT PLANTS
Other industrial application of the TECNADIS METALCOAT “Easy-To-Clean” is on water treatment plants and waste processing companies, where the organic pollution is extreme. In these cases, the coating is used to facilitate the cleaning of such facilities, reaching considerable savings because of resources optimisation, as well as to protect them against the corrosion, since the acids and vapours that are released from the decomposition of organic matter are highly corrosive.

Problem: The installations with corrosive environment undergo various problems by oxidation of the materials. In the case of sludge lines of a Waste Water Treatment Plant, the environment becomes highly corrosive as a result of acid vapours that are generated during the process. Because of this matter, the metallic elements should be protected with thick layers of paint. In the case of valves where the thickness variation is limited in order to proper operation, common paints can not be used. As a consequence, these valves should be often replaced because of the oxide layer that is created and which makes difficult the movement and rotation of them, ceasing to be functional.
Application: Tecnadis Metalcoat “Easy-To-Clean” has been applied on brass valves covered in nickel from a sludge line of the Waste Water Treatment Plant of Estella (Navarre).
Results: Several valves of the Waste Water Treatment Plant of Estella, which are operating in parallel, were treated with Tecnan coating, and after two months, it was verified that the not treated valves were corroded, and therefore, their manipulation was very complicated, whereas the valves treated with Tecnadis Metalcoat “Easy-To-Clean” were totally immaculate. These valves go on in operation for more than one year and a half after their installation.
