What Is PORTA-TAB Used For?

PORTA-TAB is a commercial holding tank deodorizer tablet used to control odors in portable toilets and restroom trailers. It is designed for portable sanitation operators who need reliable odor control in cold climates, winter service routes, and demanding operating conditions.

As a tablet-based holding tank treatment, PORTA-TAB simplifies servicing while delivering consistent results. It is ideal for operators seeking a compact, easy-to-handle alternative to liquids or packets without sacrificing performance.

How Does PORTA-TAB Work?

PORTA-TAB features an effervescent, self-mixing formula that activates immediately upon contact with water. As the tablet dissolves, it disperses deodorizing ingredients evenly throughout the holding tank, ensuring uniform treatment without manual agitation.
