Odor Neutralization System
The SweetTank™ concept has been developed to stop odors in yacht and RV holding tanks without the use of chemicals or filters. SweetTank™ is standard equipment on Thermopure-2® Type-I MSD, is optional in GROCO® Type-III MSD units, and is offered in several retrofit kits to fit existing holding tanks.
Contact GROCO® if you have questions, for the exact kit to accommodate your specific application needs.
Aerobic and anaerobic bacteria coexist naturally in raw sewage, but it is the anaerobic bacteria that produce undesirable odors. By inducing a constant flow of air into the holding tank through a submerged aeration tube, SweetTank™ produces an oxygen-rich environment in which the anaerobic bacteria cannot thrive, thus eliminating unpleasant odors!
The heart of the SweetTank™ system is a compact module that operates continuously to deliver air to the holding tank using less than 3-watts of DC power. For yachts where AC power is always available, an AC powered SweetTank™ module is offered.
-
STK-18 (Standard Model) aeration equipment fits into any available 1-1/2" NPT threaded fitting in the top or side of the tank.
-
If there is no 1-1/2" NPT opening available the kit can be installed into a 2-1/2" hole cut in the tank top or side. Mounting hardware is included.

STK-18 fits tanks up to 18" deep.
Contact GROCO® for installation in tanks deeper than 18".
