DRP Accelerator vs Brenntag: an Oxygen Program, Not a Packaged Bioaugmentation Catalog

DRP Accelerator is the stronger choice for a lift station, force main or lagoon that needs hydrogen sulfide prevented at the source: we add usable oxygen for the bacteria already living in the wastewater, and we add no bacteria and no enzymes of our own. Brenntag, a global chemical and ingredients distributor, sells a packaged "Biological Solutions Product Line" for wastewater bioaugmentation under its own Arkea and ProBlend house brands, alongside a carbon source product and a floc control product, as its website describes it (September 2026). Adding bacteria the right way calls for a lab to evaluate what bacteria a system already has, an analysis that costs money and has to be repeated as a regular part of the program, and what is often seen instead is that it works at first, the lab work does not happen, and the added culture dies off or has little or no effect; we only add oxygen, so think of it as supercharging your bacteria, and it works continuously. A system already running one of Brenntag's products does not have to give it up either: DRP Accelerator dosed upstream sets a baseline and measures from there, and the added product typically has less to do once oxygen reaches the water first.

Two starting points

Brenntag is a global chemical and ingredients distributor, calling itself “the global market leader in chemicals and ingredients distribution,” a company that “connects chemical manufacturers and chemical users in a value-adding partnership.” For wastewater, Brenntag sells a packaged “Biological Solutions Product Line” under its own Arkea and ProBlend house brands: bacterial cultures, an enzyme product for fats, oils and grease, several nutrient blends, a concentrated liquid carbon source and a floc control chemical. Brenntag’s own product sheet defines bioaugmentation as “the addition of bacterial cultures, enzymes, and micronutrients to increase the digestion capacity of a wastewater system,” and its pages do not name the manufacturer behind the Arkea or ProBlend formulas, as its website describes it (September 2026).

DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater. We add no bacteria and no enzymes. With that oxygen available, the bacteria stop drawing it from sulfate, so the sulfide that becomes hydrogen sulfide is never formed, and the same aerobic bacteria go on to digest the fats, oils, grease and organic sludge in one program, instead of an enzyme product and a bacterial culture ordered separately for that job.

Four things decide which approach fits a system: what each one adds to the water, when it acts relative to the moment hydrogen sulfide forms, what stays behind once it has worked, and what it costs to run in capital and handling terms. The rest of this page walks through each of those four in turn, starting with the table below.

At a glance

The table below lines up the same eight questions worth asking of any bioaugmentation product, Brenntag’s biological line and DRP Accelerator side by side, with DRP Accelerator listed first because that is the answer we are recommending.

Factor	DRP Accelerator	Brenntag
What is added	Usable oxygen for the bacteria already present; no bacteria, no enzymes	Bacterial cultures, an enzyme product, nutrient blends, a carbon source and a floc control chemical, as its website describes its Biological Solutions Product Line
When it acts	Before the sulfide pathway starts	On the schedule and at the point the ordered product is applied
What stays downstream	Nothing; consumed as the bacteria use the oxygen	Depends on the product; Arkea Culture Media ships in a mesh bag and BioBoost CR in a time release block, per its product sheet
Where it reaches	As far upstream as water and power allow, into anaerobic zones aeration never reaches	Wherever the ordered product is placed by hand or added to the flow
FOG and sludge	Digested by the same aerobic bacteria	One enzyme only product addresses FOG; sludge reduction is stated qualitatively, tied to ammonium compound control, with no mechanism given for preventing hydrogen sulfide
Capital and handling	No capital purchase; a monthly service we run	Packaged product ordered through its own portal; no dosing equipment or service network described on its site
How it is measured	A baseline and follow up readings as part of the monthly service	Product selection support only; no ongoing measurement protocol stated
Markets it names	Collection systems, lift stations, force mains and lagoons across the markets we serve	Wastewater treatment plants and lift stations, anaerobic lagoons, drains, porta potties and septic systems, plus municipal water treatment and industrial markets on its broader pages

Where DRP Accelerator is the stronger choice

Prevention, not another package to apply. Hydrogen sulfide is never formed once the bacteria already in the wastewater have usable oxygen to draw on, instead of adding bacteria or enzymes from outside that still need an oxygen supply of their own before they can do anything once they arrive.
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.
Nothing added that stays behind. DRP Accelerator is consumed as the bacteria use its oxygen, so no added culture, enzyme or nutrient blend and no leftover mesh bag, block or bucket sit in the system once the job is done.
FOG and organic sludge digested by the same bacteria. The oxygen that keeps sulfide from forming also feeds the aerobic bacteria that break down fats, oils, grease and settled solids, one program instead of a separate enzyme product ordered for that job alone.
Upstream reach a packaged additive cannot match. We dose as far upstream as water and power allow, into anaerobic zones a bag, block or bucket placed by hand never reaches: force mains, wet wells, sludge blankets.
No capital purchase, a service we run and measure. DRP Accelerator runs as a monthly program built around a measured baseline and follow up readings, not a catalog order placed and left to work on its own, with documented before and after readings from systems that made the switch.
Works in anaerobic and aerobic water alike. The same oxygen that stops hydrogen sulfide from forming in an anaerobic force main also supports the aerobic bacteria doing the rest of the digestion work, so one program covers water a single packaged product was never built to reach on its own.

Where Brenntag has the edge

Brenntag’s own website supports a few real advantages, and it is worth naming them plainly rather than pretending the choice is always one sided.

One distributor’s whole catalog. Brenntag’s Biological Solutions Product Line covers bacterial cultures, an enzyme product for FOG, several nutrient blends, a carbon source and a floc control chemical, all ordered through its own connect portal, a real advantage for a buyer who wants a full range of additives from a single supply chain rather than assembled from several suppliers.
A named formula for a known problem, with selection help. Brenntag advertises “expertise, and testing solutions needed to assist in product selection,” and lists individual formulas by name, including one it says protects the existing microbial community against an adverse, possibly toxic substance, useful when the problem is already identified and specific.
A low commitment format that needs no dosing equipment. Two of Brenntag’s products ship ready to place by hand: Arkea Culture Media in a mesh bag for continuous addition and BioBoost CR as a time release block, either one a way to add bacteria to a small tank without a pump or a service contract.

Where DRP Accelerator pulls ahead is what happens once oxygen, not another organism, reaches the water: the sulfide pathway never starts, and the fats, oils, grease and sludge get digested by the same bacteria already on site, in one program instead of a separate enzyme product ordered for that job alone.

Already running Brenntag? Add DRP Accelerator upstream

Nothing has to come out first. We dose DRP Accelerator upstream of whatever Brenntag product is already running, set a baseline against your current readings, and measure from there before anything about the existing order changes. With usable oxygen reaching the water before Brenntag’s bacteria, enzymes or nutrients do, the added product typically has less work left to do; many sites reduce or retire it once the readings hold against that baseline, and some keep a smaller order in reserve rather than dropping it entirely, a decision that stays with the operator, not with us. Gas monitors and confined space entry procedures stay in place either way; nothing about adding an upstream oxygen program changes what has to be true for anyone entering a wet well or a force main manhole.

How to decide

Find where the oxygen runs out. Walk the system from the point waste enters to the point it leaves, and mark where dissolved oxygen disappears: a force main, a wet well, a sludge blanket. That is where hydrogen sulfide is being made, and it is the point any real comparison has to start from.
Ask what each product adds, and what stays behind. Brenntag’s line adds bacterial cultures, enzymes, nutrients, a carbon source or a floc control chemical, with two products shipped in a mesh bag or a time release block. DRP Accelerator adds usable oxygen that is consumed as the bacteria use it, leaving nothing of the product itself behind. For the general case against packaged bacteria additives, see our comparison of bacteria additives.
Ask what happens to FOG and sludge. Brenntag sells one enzyme product for fats, oils and grease as a separate item; ask whether that is already included in what is ordered, or whether the fats, oils, grease and organic solids in the system are being left for something else to handle.
Ask what it costs in capital and handling, and how the result is measured. Compare ordering packaged product through a portal against a monthly service with no capital purchase, and ask how each vendor proposes to show you, in writing, that the result is actually working.

Ask both vendors for the same page

Ask Brenntag and ask us for the same thing: where the product actually reaches in the system, what stays behind once it has worked, and how the result gets measured over time. A distributor with a wide catalog can usually answer the first question with a product name; fewer can answer the second and third with anything more than a selection guide. We will show you that same page on your own system: the dosing point we would use, the baseline we would set, and the readings we would bring back to you as the program runs. Contact us and we will walk through it together, on your data, not a sales sheet. We say all of this in public because it holds up in public.

COMMON QUESTIONS

Straight answers.

Is DRP Accelerator a good alternative to Brenntag?+

Yes, DRP Accelerator prevents hydrogen sulfide from forming instead of adding another organism that still needs oxygen to work. Brenntag sells a packaged "Biological Solutions Product Line" of bacterial cultures, an enzyme product, nutrient blends, a carbon source and a floc control chemical, as its website describes it, with no mechanism stated for keeping hydrogen sulfide from forming in the first place. DRP Accelerator is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater, so those bacteria stop drawing it from sulfate and hydrogen sulfide is never formed. It is consumed as the bacteria use its oxygen, leaving no chemical additives behind, and it runs as a monthly service with no capital purchase. It can also be dosed upstream of Brenntag's products already in place, without removing anything first.

What is the main difference between DRP Accelerator and Brenntag?+

Brenntag adds bacterial cultures, enzymes, micronutrients, a carbon source or a floc control chemical from outside the system, packaged and ordered through its own portal. Adding bacteria that way only works if a lab keeps checking what is already present, since the added culture can otherwise die off or do little once it ships. DRP Accelerator adds none of that, only usable oxygen for the bacteria already living in the wastewater, and it is consumed as those bacteria use it.

Where does Brenntag fall short?+

Brenntag's product sheet does not name the manufacturer behind its Arkea or ProBlend formulas, and its pages describe outcomes such as sludge, ammonia and odor reduction in qualitative terms with no mechanism given for stopping hydrogen sulfide before it forms. Nor does it say whether a lab evaluates what bacteria a system already has before an Arkea or ProBlend culture ships, the analysis that has to be repeated as a regular part of the program if the added bacteria are going to do more than work for a while and then die off. No dosing equipment, monthly visit or measurement protocol appears on the pages Brenntag publishes; instead it offers product selection support and ships packaged bags, buckets, mesh bags, blocks, totes and drums for the customer to apply.

Do we have to stop using Brenntag to start DRP Accelerator?+

No. We dose DRP Accelerator upstream of whatever Brenntag product is already running, without removing or shutting anything down first, and set a baseline against your current readings before making any change to what is already in place.

Can the two run at the same time?+

Yes. DRP Accelerator dosed upstream and a Brenntag product dosed at its existing point can run together; with more oxygen reaching the water first, the added product typically has less work to do, and the two can be adjusted against each other as the readings come in.

What happens to Brenntag once DRP Accelerator is running?+

The added product typically has less to do once oxygen is reaching the water upstream of it, and many sites reduce or retire it once the readings hold against the baseline we set. Some sites keep a smaller order in reserve rather than dropping it entirely; either way, the decision is measured against readings, not assumed.

Is Waste Water Innovations affiliated with Brenntag?+

No. We are not affiliated with or endorsed by Brenntag. Brenntag, Arkea and ProBlend are names and marks that belong to their owners, and the facts about Brenntag above come from its own website as of September 2026 and may have changed since. Confirm current details with Brenntag before buying.
