SWEETTANK™
STK Series: Odor
Neutralization System
Compatible with 155 and ZDS Series
The SweetTank™ concept has been developed by GROCO® to stop odors in yacht and RV holding tanks without the use of chemicals or filters.
SweetTank™
comes as standard equipment on Thermopure-2® Type-I
MSD, and is optional with GROCO® Type-III
MSD units (specifically Model ZDS).
We also offer
SweetTank™ in several retrofit kits to fit existing holding tanks.
Aerobic and anaerobic bacteria coexist naturally in raw sewage. It is the anaerobic bacteria that produce undesirable odors. Introducing a constant flow of air into the tank produces an oxygen-rich environment in which bacteria cannot thrive, thus eliminating unpleasant odors.
The compact module that constantly delivers oxygen to the holding tank requires less than 3 watts of DC power. Also available in an AC model.
