DRP Accelerator vs Veolia Water Technologies: the Alternative That Adds No Bacteria

DRP Accelerator is the stronger choice for a lift station, force main or lagoon that needs hydrogen sulfide prevented rather than treated, at no capital cost. Veolia Water Technologies sells BioPlus, a bioaugmentation chemical line that its website describes, as of September 2026, as blends of naturally occurring, adapted microorganisms with enzymes and nutrient supplements added; we add no bacteria and no enzymes of our own, only usable oxygen for the bacteria already living in your wastewater. Adding bacteria properly takes a lab evaluation of what bacteria are already present, an analysis that is costly and has to repeat as a regular part of the program, and what is often seen is that it works at first, the lab work rarely happens, and the added culture dies off or has little or no effect; we only add oxygen, think of it as supercharging the bacteria already there, and it works continuously. If BioPlus, or any bioaugmentation product, is already running at your site, DRP Accelerator adds upstream of it, with nothing to remove first.

One adds bacteria, fungi, enzymes and nutrients from outside. We feed the bacteria already living in your wastewater instead.

Two starting points

Veolia Water Technologies sells a bioaugmentation chemical line it calls BioPlus, described on its own website, as of September 2026, as blends of naturally occurring, adapted microorganisms with enzymes and nutrient supplements added, the organisms drawn from bacteria and fungi isolated from the environment. Alongside BioPlus, Veolia offers two support tools: BioHealth, an ATP-based test for biomass activity, and InSight, a monitoring platform. Its site names COD and BOD removal, fats, oils and grease degradation, organic sludge degradation, and ammonia removal during nitrification as applications, sold into municipal wastewater plants and industrial sectors including chemical processing, food and beverage, pulp and paper, and oil, gas and refining, and it sells membrane bioreactors and membrane-aerated biofilm reactors as a separate equipment line from BioPlus.

We start from a different point of intervention. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater, and we add no bacteria and no enzymes of our own. With that oxygen available, the bacteria stop drawing it from sulfate, so hydrogen sulfide is not formed, and the same aerobic bacteria dig into fats, oils, grease and organic sludge that anaerobic conditions leave alone. The compound is consumed as the bacteria use it, so nothing of it stays downstream, and we dose it as far upstream as water and power allow, running it as a monthly service with no capital purchase.

The reason the starting point matters is what happens in the pipe itself. A sewer line, a wet well or a lagoon bottom runs out of dissolved oxygen fast, and once it does, the bacteria already 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. Any product that changes that chemistry has to reach the water where the oxygen shortage actually is, not just the tank or the piping where it is convenient to dose.

Four things decide which one fits your system: what each one adds, when it acts relative to the moment hydrogen sulfide forms, what stays in the water once it has worked, and what it costs to run in capital and handling terms.

At a glance

Factor	DRP Accelerator	Veolia Water Technologies
What is added	Usable oxygen for the bacteria already in the wastewater; no bacteria or enzymes added	Bacteria, fungi, enzymes and nutrient supplements, as its website describes BioPlus
When it acts	Before hydrogen sulfide forms, since those bacteria stop drawing oxygen from sulfate once oxygen is available	After BioPlus is added, once the added organisms and enzymes take hold
What stays downstream	Nothing; the compound is consumed as the bacteria use its oxygen, so no chemical additives are left behind	Not stated on Veolia’s site
Where it reaches	As far upstream as water and power allow, into force mains, wet wells and lagoon bottoms	Dosed in bulk, pail and pound quantities, or fed continuously into plant piping, per its case studies
FOG and sludge	Digested by the same aerobic bacteria once they have the oxygen	A separate line built around bacteria, enzymes and surfactants for oil and grease clean-up
Capital and handling	No capital purchase; arrives dry, mixed and activated in a tank on site	Chemical dosed in bulk, pail and pound quantities, plus separate biological treatment equipment sold on its own
How it is measured	Against a measured baseline, with follow-up readings as part of the monthly service	Veolia’s own BioHealth activity test and InSight monitoring platform

Where DRP Accelerator is the stronger choice

Prevention instead of capture. Hydrogen sulfide is never formed in the first place, because the bacteria already in your wastewater get oxygen before they would otherwise strip it from sulfate. BioPlus, and every added-organism product, works after that gas already exists, once the added organisms and enzymes have had time to take hold.
Nothing added that stays behind. We add no bacteria, fungi, enzymes or nutrient supplements, and DRP Accelerator is consumed as the bacteria use its oxygen, so no chemical additives are left in the water once the job is done. There is no added culture competing with the native population for room to work.
FOG and sludge digested by the same bacteria. The oxygen we supply lets the aerobic bacteria already on site work through fats, oils and grease and organic sludge, instead of adding a separate product line built around bacteria, enzymes and surfactants just for oil and grease clean-up.
Upstream reach where aeration cannot go. We dose as far upstream as water and power allow, into force mains, wet wells and lagoon bottoms that a plant’s blowers, and a chemical fed only into plant piping ahead of treatment, never reach, in anaerobic and aerobic water alike, with documented before-and-after readings in our case studies.
No capital purchase, a monthly service we run and measure. DRP Accelerator arrives dry, is mixed and activated in a tank on site, and runs as a monthly service built around a measured baseline and follow-up readings, not a bulk chemical order, a pail or pound purchase, or an equipment purchase.
No lab work to keep an added culture alive. To add bacteria properly, a lab has to evaluate what bacteria are already present, and that analysis is costly and has to repeat as a regular part of the program. What is often seen is that it works at first, the lab work rarely happens, and the added culture dies off or has little or no effect. We only add oxygen. Think of it as supercharging your bacteria, and it works continuously. Our bacteria growth test measured that difference directly.

Where Veolia Water Technologies has the edge

One vendor for chemistry and equipment. Veolia sells BioPlus bioaugmentation chemistry alongside its own biological treatment equipment, membrane bioreactors and membrane-aerated biofilm reactors, so a large municipal plant or an industrial site such as a refinery, a chemical plant or a food or beverage producer can source both under a single contract, without coordinating between separate vendors for chemistry and equipment.
In-house, lab-style monitoring. BioHealth and InSight give an operation already set up for its own activity testing and monitoring a tool built to match its BioPlus dosing, which suits a plant that already runs that kind of program internally.
A named line for an ammonia upset, and a broader catalog. Veolia’s site lists formulations for oil and grease clean-up, nutrient-only products, and blends built around facultative organisms and oxygen donors for low-oxygen conditions, plus product lines aimed directly at recovering ammonia removal during nitrification, a specific upset that a broad catalog can be useful for matching to.

Where DRP Accelerator pulls ahead is the moment the work happens: we prevent hydrogen sulfide before it forms and leave nothing behind, instead of adding organisms, enzymes and nutrients that act once they are already in the water.

Already running Veolia Water Technologies? add DRP Accelerator upstream

Nothing about BioPlus 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 BioPlus, or any bioaugmentation 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 bioaugmentation 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.

How to decide

Find where your own system actually runs out of oxygen, the wet well, the force main or the lagoon bottom, not the plant’s aeration basin where blowers already reach.
Ask what each product adds to the water, whether that is bacteria, fungi, enzymes and nutrients from outside or usable oxygen for the population already there, and what, if anything, stays behind once it has done its work.
Ask what happens to fats, oils, grease and sludge at that same point, and whether that takes a separate product line or the same bacteria already doing the rest of the job once they have the oxygen to do it.
Ask what it costs to run in capital and handling terms, whether it is a bulk chemical order, a pail or pound purchase, or an equipment purchase, and how the result gets measured, an in-house activity test or a baseline set before the first dose.

Ask both vendors for the same page

Ask Veolia Water Technologies, 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. 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 Veolia Water Technologies?+

Yes, for the kind of site that wants hydrogen sulfide prevented rather than treated, with no bacteria, fungi or enzymes added from outside. Veolia Water Technologies sells BioPlus, a bioaugmentation chemical line that its website describes, as of September 2026, as blends of adapted microorganisms with enzymes and nutrient supplements. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in your wastewater instead, and that oxygen keeps those bacteria from drawing it out of sulfate, which is how hydrogen sulfide forms. 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 large municipal plant or an industrial site that wants one vendor for chemistry, equipment and monitoring under a single contract, Veolia Water Technologies remains a reasonable choice.

What is the main difference between DRP Accelerator and Veolia Water Technologies?+

The main difference is what each one adds. BioPlus, as Veolia's website describes it, adds bacteria, fungi, enzymes and nutrient supplements from outside the wastewater system. Adding those organisms properly calls for a lab to check what bacteria are already present, an analysis that is costly and has to repeat as a regular part of the program, and without it an added culture often works at first, then dies off or has little effect. DRP Accelerator adds none of those; we add usable oxygen to the bacteria already living there, so hydrogen sulfide is prevented rather than treated after it forms.

Where does Veolia Water Technologies fall short?+

Veolia's own site does not state what, if anything, stays in the water downstream once BioPlus has done its work. Its case studies describe BioPlus dosed in bulk, pail and pound quantities, or fed continuously into plant piping, which suits a plant with the staff and storage for that kind of chemical program more than a single lift station or lagoon looking for a low-capital, upstream fix. Adding bacteria this way also depends on lab work that is costly and easy to let slide, checking what bacteria are already present before more is added, and without it an added culture often works at first and then dies off or has little effect.

Do we have to stop using Veolia Water Technologies to start DRP Accelerator?+

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

Can DRP Accelerator and Veolia Water Technologies run at the same time?+

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

What happens to Veolia Water Technologies once DRP Accelerator is running?+

BioPlus 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 bioaugmentation product once the readings against baseline hold. Gas monitors and confined-space procedures stay in place regardless.

Is Waste Water Innovations affiliated with Veolia Water Technologies?+

No. Waste Water Innovations is not affiliated with, endorsed by or sponsored by Veolia Water Technologies. Veolia Water Technologies, BioPlus, BioHealth and InSight are the property of their respective owners, and every statement about them on this page comes from Veolia's own website as of September 2026.
