<p>Dentrifying backing in a tablet form is periodically introduced into a home or commercial sewage treatment system, and specifically into an underground denitrification chamber. The system uses ground temperature to promote dentrifying bacteria activity to aid in sewage denitrification. The tablets are periodically dispensed with a power-driven dispenser that periodically drops a tablet below ground into the underground denitrification chamber.</p> |
