These bacteria are used to activate bio digester with the healthy bacteria which multiplies with time. They help to reduce surface and bottom solids. The build-up of surface and bottom solids can carry over to the soaking area and cause it to become clogged.
Once clogged, the system has nowhere to drain and the tank fills up, causing a backup in the home and thus requiring frequent exhaustion. Use of bacteria restores the biological population of good worker bacteria and enzymes which reduce solids.
The beneficial bacteria also get carried over to the soaking area to reduce solids and help prevent clogging.
