DRP Accelerator vs the Companies That Add Bacteria to Wastewater: the One That Adds Oxygen Instead

Search for companies that add bacteria to wastewater and nine names come up again and again: Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet, Drylet and REX-BAC-T Technologies, each selling its own bacteria, fungi, enzyme or nutrient product, in its own words, on its own website, checked September 2026. DRP Accelerator is the one option on this page that adds none of that: an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater, so hydrogen sulfide is prevented instead of treated and fats, oils, grease and sludge get digested by bacteria that were already there. This page sets all nine beside DRP Accelerator in one table, with a full page linked for each, and it works the same way whether your system is running one of these products today or none at all: we dose upstream of whatever is already there, set a baseline, and measure from it.

Nine companies add bacteria, fungi, enzymes or nutrients to wastewater. We add usable oxygen to the bacteria already there instead.

Bioaugmentation is the addition of outside bacteria, fungi or enzyme cultures to a wastewater system.
Biostimulation is a change in conditions, such as added oxygen, for the bacteria already living in a system, rather than the addition of new organisms.
Hydrogen sulfide forms when bacteria draw oxygen from sulfate once the dissolved oxygen already in wastewater has been used up.
Companies that sell bacteria for wastewater treatment package their products as a liquid, a powder, a tablet, a dissolving block, or bacteria carried on an engineered particle.
An inorganic compound that carries usable oxygen to bacteria already living in wastewater is consumed as those bacteria use it.
A distributor and dealer network is the main sales channel several wastewater bacteria manufacturers name on their own websites.

Read this first

Every company on this page adds something to your wastewater that was not there before: a bacterial strain, a fungal culture, an enzyme, or a nutrient blend, packaged as a liquid, a powder, a tablet, a dissolving block, or bacteria carried on an engineered particle. DRP Accelerator is the one option here that adds none of that.

They add organisms that depend on lab work. To add a strain properly, a lab has to evaluate what bacteria are already present, so anyone knows whether the new strain will have any effect at all, and that evaluation is costly and has to be repeated as a regular part of the program. What we often see instead is that the product works for a while, the lab work never gets repeated, and the added culture dies off or has little or no effect, as our bacteria additives comparison explains.
We only add oxygen, and it works continuously. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater, continuously rather than in a single dosed batch: think of it as supercharging the bacteria you already have, as our bacteria growth test shows. Once that oxygen is available, those bacteria stop drawing it from sulfate, the reaction that produces hydrogen sulfide, and the same oxygen lets the aerobic bacteria already on site digest fats, oils, grease and organic sludge that an oxygen-starved system leaves alone.

Added organisms against fed organisms is the whole case on this page.

That table is most of the decision. If the DRP Accelerator row already reads your way, contact us and we will show you the program on your own system.

Veolia Water Technologies: bioaugmentation chemistry and equipment

Veolia Water Technologies sells BioPlus, bacteria, fungi, enzymes and nutrient supplements dosed in bulk liquid or dry blends, by the pail and pound or fed continuously into a sump, sold into municipal plants and industrial sectors including chemical processing, food and beverage, pulp and paper, and oil, gas and refining. Read the full comparison for the complete table and sourcing. DRP Accelerator adds none of that: we feed the bacteria already living in your wastewater instead of adding more from outside.

Microbial Discovery Group: Bacillus strains through a dealer network

Microbial Discovery Group sells Bacillus bacteria strains and a micronutrient and biostimulant blend called Biotifx, packaged as liquid, powder and solid forms, including a water-soluble packet and a mesh-bag hanging block, sold mostly through a distributor and dealer network into municipal plants, lift stations, sludge tanks, lagoons and residential or septic use through supplier partners. Read the full comparison for the complete table and sourcing. DRP Accelerator needs no dealer network and no added Bacillus strain; we run the program ourselves and feed the bacteria already on site.

EnviroZyme: fermented blends for a named job

EnviroZyme ferments bacterial blends built for specific jobs, nitrification, organics reduction, FOG and odor, sold as liquid concentrate, powder, pouch packaging or a dissolving block, direct and through distributor partners across markets from agriculture and aquaculture to municipal, pulp and paper, and septic or remote sites. Read the full comparison for the complete table and sourcing. DRP Accelerator does not need a different named product for each job; the same oxygen program answers all of them.

Ecological Laboratories: MICROBE-LIFT bottles and packets

Ecological Laboratories sells MICROBE-LIFT, bacterial consortiums with dedicated nitrifying strains in some products and a separate micronutrient product, packaged as liquid bottles and dry water-soluble packets that its site describes as hand-dosed, with no activation step named, sold through a distributor and dealer network and directly online. Read the full comparison for the complete table and sourcing. DRP Accelerator arrives dry and is mixed and activated in a tank we run on site, not dosed by hand from a bottle.

Brenntag: a distributor’s bioaugmentation catalog

Brenntag distributes Arkea and ProBlend, bacterial cultures, enzymes, micronutrients, a carbon source and a floc-control chemical packaged as bags, buckets, blocks, totes and drums, including a mesh-bag culture media and a time-release block, ordered through its own connect portal; its product sheet does not name the manufacturer behind the formulas. Read the full comparison for the complete table and sourcing. We tell you exactly what DRP Accelerator is and who makes it, and it needs no floc-control chemical added alongside it.

Aster Bio: named microbial blends sold direct

Aster Bio sells named microbial blends isolated for specific functions, with enzymes and surfactants in some products, as concentrated dry powder or liquid in drums and totes, pump-metered or hand-dosed, sold direct with no dealer network named. Read the full comparison for the complete table and sourcing. DRP Accelerator needs no matching of a named strain to a named pollutant; it feeds the bacteria the system already has.

Bio-Green Planet: Bacillus blocks, tablets and powders

Bio-Green Planet sells Bacillus bacteria blends, paired with enzymes in some products, across named product lines packaged as powder, liquid, tablet and slow-dissolve block, sized by weight or count, and sold direct, through distributors, and through OEM and private-label partners. Read the full comparison for the complete table and sourcing. DRP Accelerator runs as one measured program across those same markets rather than a catalog of separate products.

Drylet: bacteria carried on an engineered particle

Drylet embeds bacterial cultures in engineered porous particles, sold as a dry powder applied daily or per pit pump-out with no mixing equipment described, mostly direct from the maker with a dealer network for one livestock product. Read the full comparison for the complete table and sourcing. DRP Accelerator needs no engineered carrier particle; the oxygen we add goes straight to the bacteria already living in the water.

REX-BAC-T Technologies: bulk powder bacteria and enzymes since 1983

REX-BAC-T Technologies has supplied microbial biotechnology products, equipment and systems since 1983, selling bacteria and enzyme formulations under named product lines such as BP-1200, EP-1201 and EP-1400, as bulk powder, liquid or solid formulations, to residential, commercial, industrial, institutional, agricultural and municipal customers. Read the full comparison for the complete table and sourcing. DRP Accelerator needs no bulk powder order or a separate named product line for each job; we add usable oxygen to the bacteria already living in your wastewater instead.

DRP Accelerator: the oxygen program

DRP Accelerator is an inorganic compound that carries usable oxygen in a form the bacteria already living in your wastewater can use. We add no bacteria and no enzymes. A sewer line, a wet well or a lagoon bottom runs out of dissolved oxygen fast, and once it does, the bacteria there take their oxygen from sulfate instead, and the sulfide left behind becomes hydrogen sulfide gas: the smell, the corrosion, and the gas that kills people in a confined wet well. Give those same bacteria a supply of usable oxygen and they take that first, so the sulfide that becomes H2S never gets made. The same oxygen lets the aerobic bacteria already on site work through fats, oils, grease and settled solids that anaerobic conditions leave alone.

We review your data, work out flow and volume, calculate dose and frequency, and survey the site for a delivery point as far upstream as water and power allow: a lift station, a headworks channel, a wash-down line, or the pond itself. The product arrives dry; we mix and activate it in a tank on site, and it drips into the flow continuously. We monitor tank levels remotely and come back to replenish on a schedule set by tank size. There is no capital purchase: it runs as a monthly service, for as long as you want the result, measured against a baseline we set before the first dose and readings we take after.

Six questions that sort any vendor

What does it add to the water: a bacterial strain, a fungal culture, an enzyme, a nutrient blend, bacteria on an engineered particle, or usable oxygen for the population already there?
When does it act: before hydrogen sulfide forms, or after, once an added organism or enzyme has had time to take hold?
What stays in the water downstream once it has done its work, and does the company’s own site say?
Does it also reach fats, oils, grease and sludge, or does that take a separate product line?
What does it cost to run: a bulk chemical order, a pail, bottle or block purchase, and dosing equipment, or a measured monthly service with no capital purchase?
How is the result measured: an in-house activity test sold alongside the product, or a baseline set before the first dose with readings taken against it?

Already dosing one of these? Add DRP Accelerator upstream

Nothing about any of these nine products has to be removed to add DRP Accelerator. We review your data, work out flow and volume, and survey the site for a dosing point as far upstream as water and power allow, the same way we did at a Texas lift station: a wet well, a headworks channel, or the pond itself, upstream of wherever a bacteria, fungi or enzyme product is already dosed. We set a measured baseline before changing anything else, then take follow-up readings against it on a schedule that matches your tank size. With usable oxygen reaching the bacteria before hydrogen sulfide can form, the added product typically has less work left to do, and many sites reduce or retire it once the readings hold, though that decision is always yours to make against your own numbers, not ours. Gas monitors and confined-space procedures at a lift station or wet well stay in place regardless of what the readings show. Our case studies show the same upstream approach at work.

Ask every vendor for the same page

Ask each of these nine companies, and ask us, for the same page: what is added, when it acts relative to the moment hydrogen sulfide forms, what stays downstream, and what it costs to run in capital and handling terms. A fair vendor answers all four questions in the same terms for its own product, not just the ones that favor it. We will show you the program on your own system: where we would set the dosing point, what a measured baseline looks like, and how we report the readings against it once the service is running. Contact us and we will walk through it together, or reach us through our contact page if you would rather start there. Our FAQ page answers more of the questions operators ask before they call. We say all of this in public, on this page, because it holds up in public.

COMMON QUESTIONS

Straight answers.

Is DRP Accelerator a good alternative to the companies that add bacteria to wastewater?+

Yes, for a lift station, force main or lagoon that needs hydrogen sulfide prevented rather than treated, with no bacteria, fungi or enzymes added from outside. Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet, Drylet and REX-BAC-T Technologies each sell a version of the same idea, on their own websites, as of September 2026: bacteria, fungi, enzymes or nutrients added to the water as a liquid, a powder, a tablet, a dissolving block, or bacteria carried on an engineered particle. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater instead, so the reaction that forms hydrogen sulfide gas never gets the oxygen shortage it needs to happen. It is consumed as the bacteria use it, so nothing of it stays downstream, and it arrives as a monthly service with no capital purchase. For a plant that wants one manufacturer's catalog across several problems, or a named strain for an ammonia upset, one of these nine companies remains a reasonable choice.

What is the main difference between DRP Accelerator and the companies that add bacteria to wastewater?+

The main difference is what each one adds. All nine companies on this page add something to the water that was not there before: a bacterial strain, a fungal culture, an enzyme, a nutrient blend, or bacteria seeded onto a manufactured particle. To work, an added strain needs a lab to evaluate what bacteria are already present, so anyone knows whether the new strain will have any effect, and that evaluation is costly and has to be repeated as a regular part of the program; often the lab work never happens, and the added culture dies off or has little or no effect. DRP Accelerator adds none of that; it adds usable oxygen to the bacteria already living in the wastewater, continuously, so think of it as supercharging the bacteria that are already there, and hydrogen sulfide is prevented rather than treated once it has already formed.

Where do these companies fall short?+

Their own websites describe products built around bacteria, fungi or enzymes that work on organic material, ammonia, odor compounds or a targeted pollutant once conditions in the system support that activity, rather than a change to the oxygen already reaching the bacteria that are there. Several sell mostly through a distributor and dealer network rather than direct: Microbial Discovery Group, Ecological Laboratories, and Drylet for its livestock product line. Veolia Water Technologies, EnviroZyme and Aster Bio describe direct sale alongside a sales team or distributor partners, and Bio-Green Planet names several channels without indicating any one is primary.

Do we have to stop using one of these products to start DRP Accelerator?+

No. We dose DRP Accelerator upstream of whatever you already run, including any of these nine products, and set a measured baseline before changing anything else. Nothing has to be removed first.

Can DRP Accelerator run at the same time as one of these products?+

Yes. The two act at different points, an added bacteria, fungi or enzyme product once it is in the system, and DRP Accelerator before hydrogen sulfide forms, so running both at once does not conflict. Many operators find the added product has less work to do once the oxygen program is running.

What happens to one of these products once DRP Accelerator is running?+

It typically has less to do once usable oxygen is reaching the bacteria already in the system, since less hydrogen sulfide is forming and less FOG and sludge is building up for it to work through. Many sites reduce or retire the added product once the readings against baseline hold. Gas monitors and confined-space procedures stay in place regardless.

Is Waste Water Innovations affiliated with any of these companies?+

No. Waste Water Innovations is not affiliated with, endorsed by or sponsored by Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet, Drylet or REX-BAC-T Technologies. Their names and product names belong to their respective owners, and every statement about them on this page comes from their own websites as of September 2026.
