Other Holding Tank Treatments:
Holding Tank treatments usually combine deodorants and germ killers to mask or eliminate offensive odors created as
waste is broken down. These treatments come in four basic formulations: Chemical, Enzyme, Nitrate, and
Bioactive.
1) Chemical Treatments — The most common. Kills bacteria immediately. Very effectively control odors by
masking smells with deodorant. Although relatively inexpensive when compared to other treatments, chemicals must
be added regularly. They are not designed to dissolve waste and are the least environmentally friendly.
2) Enzyme Treatments — Accelerate the digestion of organic materials in waste and neutralize odors at the same
time. Their toxicity is extremely low. They work quickly and completely emulsify paper and sewage. They must be
added regularly. They have a limited range of effectiveness in terms of temperature and pH. Enzymes require a tank
free from residuals of other treatment products.
3) Nitrate Treatments — Provide an interesting alternative. Oxygen is vital to bacteria in the process of breaking
down organic waste. When little air is present, as in most holding tanks, bacteria derives the oxygen from sulfates in
the waste. This produces hydrogen sulfide (stinky!) gas. When nitrates are introduced, they act as nutrients for the
bacteria, providing an alternative source of oxygen. This results in the production of nitrogen (odorless) gas. Nitrates
are environmentally friendly. They speed up the breakdown process and eliminate odors. They require a tank free of
residuals from other products. They are expensive relative to other treatments.
4) Bioactive Treatments — Contain live aerobic bacteria, which break down waste, reproduce and crowd out
anaerobic (odor-producing) bacteria. They, too, are environmentally friendly. Like enzymes, bioactive treatments
emulsify paper and sewage completely. Unlike other treatments, they multiply and continue to work long after
treatment is complete. This eliminates the need to add more between pump outs. However, the microbes require a well-
ventilated holding tank to survive. The tank must be free of residuals. Although initially expensive, bioactive treatments
become more cost effective over time because of bacteria propagation.
Our Holding Tank Treatments:
Happy Campers and Healthy Boaters are stand alone mono hydrate, highly concentrated mineral blends in an
anhydrous form. They work basically the same as a bioactive treatment. They are synergist formulated to eliminate
odor (not cover it up) and accelerate decomposition. They are activated when mixed with water. Because it withstands
hot and cold temperatures well, they keep on working so you don't have to add more before dumping.
