Break Down Sludge, Solids & Odors — at the Source.
Bio-Pure Septic & Drain + RV is a concentrated microbial and bio-enzyme treatment with Deproteinized Whey (DPW). It digests waste around the clock and eliminates odor where it starts, instead of covering it up.
- Digests waste and eliminates odors, 24/7
- Maintains septic tanks and household drains
- Works in RV holding tanks, too
- One treatment a month for a household septic system
Available as a citrus-ginger scented liquid, or an economical concentrated powder. Made in the USA.
Why DPW?
Most bacteria treatments ship dormant microbes and hope they wake up. Bio-Pure adds deproteinized whey — food for the bacteria — so they activate faster and keep working.

The Problem
When a septic system falls behind, you notice.
Septic tanks and drains depend on bacteria to break down what goes into them. When that biology can't keep up, waste accumulates faster than it's digested — and the symptoms follow.
- Odors from drains, the tank, or the yard
- Slow or gurgling drains
- Sludge, solids and grease building up
- RV holding tanks that smell on the road
The Bio-Pure Difference
What is DPW?
Deproteinized Whey (DPW) is a built-in nutrient source for beneficial bacteria. Instead of relying on dormant microbes to wake up on their own, Bio-Pure gives them what they need to get to work.
Faster bacteria activation
DPW feeds the microbes from the moment they hit the tank, so they start digesting waste sooner.
More enzyme production
Well-fed bacteria produce more of the enzymes that break down sludge, solids and grease.
Better biofilm breakdown
It helps clear the biofilm that lines pipes and tank walls, where odor-causing buildup starts.
Where To Use It
One treatment, three jobs
Septic tanks
Routine monthly maintenance to keep the biology working — or a septic shock dose to restore a system that's backing up or smells.
Household drains
Kitchen, bath and floor drains. Digests the buildup that causes slow drains and odor.
RV holding tanks
Breaks down waste and neutralizes odor on the road, at home and on the ranch.
Common Questions
Before you buy
How often should I treat my septic tank?
Once a month for routine maintenance. That's why the 4 oz powder and 32 oz liquid are each a 15-month supply: 15 treatments. Follow the directions on the label for dosing.
What's a septic shock treatment?
A larger one-off dose for restoring a system that's struggling — backing up, smelling, or untreated for a long time. Each container can be used for shock doses instead of routine treatments.
Liquid or powder — which is better?
Same biology, different format. The liquid is the simplest pour-and-go option and has a citrus-ginger scent. The powder costs less per treatment and comes in larger sizes.
Can I use it in my RV?
Yes. It works in RV holding tanks to break down waste and control odor.
What is DPW?
Deproteinized Whey — a nutrient source added so the beneficial bacteria activate faster and stay active longer. It's the main difference between Bio-Pure and bacteria-only treatments.
Stop chasing odors. Keep the biology working.
