Town development provokes an increase in the number of used-water treatment sites. In turn, these factories generate silt which must be treated. Therefore, MENART develops and equips silt treatment purification stations with: Corridor turners for silt drying. Sludges mixers with green waste coupled to a sieve. Green waste shredders. Jigger-mixers. Once treated, these sludges can be spread to enhance farming.
