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.
Available as a citrus-ginger scented liquid, or an economical concentrated powder. Made in the USA.

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.
Every container gives either the septic and drain treatments shown, or the septic shock doses for restoring a struggling system.
Citrus-ginger scent. Pour it in and the microbes do the rest.

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.

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.
DPW feeds the microbes from the moment they hit the tank, so they start digesting waste sooner.
Well-fed bacteria produce more of the enzymes that break down sludge, solids and grease.
It helps clear the biofilm that lines pipes and tank walls, where odor-causing buildup starts.
Routine monthly maintenance to keep the biology working — or a septic shock dose to restore a system that's backing up or smells.
Kitchen, bath and floor drains. Digests the buildup that causes slow drains and odor.
Breaks down waste and neutralizes odor on the road, at home and on the ranch.
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.
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.
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.
Yes. It works in RV holding tanks to break down waste and control odor.
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.
Bio-Pure Septic & Drain + RV with DPW — for septic tanks, drains and RV holding tanks.
A septic tank is a biological system: bacteria digest the solids that settle out of your wastewater, and what they cannot digest builds up as sludge. Detergents, bleach and drain openers knock that biology back, and the tank falls behind.
Bio-Pure adds task-oriented microbes and bio-enzymes, fed by DPW (deproteinized whey) so they activate quickly instead of waiting to wake up. They break down sludge, solids and scum, and eliminate the odors that come from waste sitting undigested.
Each container gives either the septic and drain treatments shown or the septic shock doses. Follow the dose on the label.
| Size | Septic | Drain | Shock |
|---|---|---|---|
| Liquid 8 oz | 4 | 16 | 1 |
| Liquid 32 oz 15-month supply | 15 | 30 | 2 |
| Powder 4 oz 15-month supply | 15 | 60 | 1 |
| Powder 14 oz | 55 | 200 | 3 |
| Powder 48 oz | 190 | 760 | 12 |
One treatment a month maintains a household septic system.
Bio-Pure does not replace pumping, and no additive should claim to. What it does is keep the tank's biology digesting solids between scheduled pump-outs, so less passes through as sludge and odors stay down.
Household septic systems and drains — kitchen, bath and floor. Barns, animal stalls and other places organic waste collects on the ranch. RV holding tanks, and boat and marine septic and drains.
A caustic drain opener burns through a clog and moves on. Bacteria digest the organic waste that caused it, and keep working between treatments. Bio-Pure is safe for pipes, all natural and biodegradable — and it is the biology, not a chemical reaction, doing the work.
Once a month for routine maintenance. That is why the 32 oz liquid and the 4 oz powder are both 15-month supplies: 15 treatments.
No. A septic tank still needs pumping on its normal schedule. Bio-Pure is what keeps the biology working between professional pump-outs.
A larger one-off dose for a system that is struggling: backing up, smelling, or untreated for a long time. Each container can be used for shock doses instead of routine treatments.
Yes. The directions list it as safe for animals, humans, plants and pipes, environmentally safe, all natural and biodegradable.
Yes. The same formula works in RV holding tanks, and the directions cover RV and boat/marine septic and drains.
Same biology, different format. The liquid is the simplest pour-and-go and has a citrus-ginger scent; the powder costs less per treatment and comes in larger sizes.
