MTM medio Filtrante:

It is a media of dioxide manganese granular used for the reduction of iron, manganese and hydrogen sulfide in drinking water. Its active surface coating oxidizes and precipitates soluble iron and manganese. Hydrogen sulfide is oxidized to sulfur. The precipitates are filtered into the granular bed and removed by backwashing also called backwashing.

It consists of a lightweight granular core with a layer of carbon dioxide. manganese. Es un ejemplo de la oxidación de contacto donde los propios medios ofrecen el potencial oxidante. Esto permite una variedad mucho más amplia de la operación que muchos otros medios de eliminación de hierro. Un nivel de h tan bajo como 6,2 puede ser tratada. El oxigeno disuelto no es esencial. El peso ligero de los medios reduce os requerimientos de agua de retro lavado. MTM requiere la regeneración, ya sea continua o intermitente para mantener su capa oxidante. Para la regeneración ya sea continua o intermitente para mantener su capacidad oxidante.

Para la regeneración continua una solución de permanganato de potasio (o cloro luego permanganato de potasio) puede ser pre-alimentada a mantener la capacidad. En este ´´último caso, el recubrimiento de dióxido de manganese acts as a catalyst to enhance the oxidation reaction and as a regulator to reduce any excess potassium permanganate concentration and prevent it from entering service lines. Continuous feed regeneration using CI2, KMnO4, or both is required for all systems that are greater than 3 cubic feet.

For intermittent regeneration use a regeneration solution of 1 1/2 2 ounces (dry weight) of potassium permanganate per cubic foot is usually sufficient. After commissioning a new litter it should be backwashed and care taken to ensure that light weight media are not washed for drainage. A new bed must be regenerated by the afternoon of installation. Operating the filter after its oxidizing capacity is exhausted will reduce its life and may cause staining. The water not treated periodically must control the parameters of the raw water. The treated water must be periodically monitored for the manganese and if iron and hydrogen sulfide are present.

When intermittent regeneration is used, samples of treated water should be taken shortly before a regeneration and immediately after a regeneration to check if the filter system is working. Concentrations of manganese High treated water levels prior to regeneration may indicate that the filter media is being destroyed or that the reduction capacity of the bed has been exceeded.

Low pH, lack of chlorine oxidant or lack of permanganate oxidant are the most likely conditions leading to media destruction. The addition of other chemicals to the influent or wash water that makes contact with the MTM media can inhibit iron, manganese or removal of hydrogen sulfide or it may degrade.
