“Zero discharge” plants

In designing its plants for industrial wastewater treatment, Tecam aims whenever possible to complete recover of process water, as demonstrated from the installation of a hundred zero liquid discharge systems in different countries. The zero liquid discharge is reachable for process water of almost all industrial fields by combination of chemical, physical and biological tecnologies. In particular, biological technologies that find an efficient application in a zero liquid discharge system are MBR (Membrane Bio-Reactor), SBR (Sequencing Batch Reactor) and MBBR (Moving Bed Biofilm Reactor). By the concentration of pollutants contained in wastewater, they allow the recycling of treated water in production process: they represent therefore an ideal answer in case of industrial cycles that produce wastewater containing highly hazardous substances, as the laws forecast very low concentration levels of them in water to discharge. An essential factor in Return On Investment calculation is the local cost of water: the installation of zero discharge systems is then particularly suitable in countries with limited water resources.
