TREATMENT TANK FUNCTION
In the treatment tank, solid waste and toilet paper is

escapes out the tank vent. The liquid then flows through
the filters to the bottom of the treatment tank, then into
the chlorinator. Microphor recommends adding a cup of
Micro Culture monthly to insure proper operation.
TREATMENT TANK VENT
The vent in the treatment tank is a key part of the
Microphor treatment process. The vent allows oxygen
