Cleaning in filtration

These systems, in turn, are divided into anaerobic and aerobic. Anaerobic septic tanks for cottages are represented by such models as Green Rock, Favorite, Elgad, Uponor Sako and T. D. But since cleaning in them occurs without air access, they clean the drains only partially. In this case, their further biological cleaning in filtration devices is necessary, which entails an additional problem of creating such devices. In addition, to install such a septic tank, it is necessary to provide access roads, since the Assencing machine must periodically delete the sediment accumulating in the septic tank.
