                  In aerobic 
                  attached-growth process, microorganisms responsible for 
                  treatment are attached to a fixed medium (plastic rings) set 
                  into volume 2. 
                  This process 
                  allows to reach high quality in effluent, including 
                  denitrification. 
                  A remote unit (electric board) insures automatic and silent 
                  operation. 
                  
                  In order to guarantee quality of effluent according to 
                  regulations, ECOPLAST SA offers a 
                  maintenance service.  |
