DRP Accelerator vs the Companies That Add Bacteria to Wastewater, Side by Side

Search "companies that add bacteria to wastewater" and the results are mostly manufacturers: businesses that grow, ferment or otherwise culture bacterial, fungal or enzyme strains, then package them as a liquid, a powder, a tablet, a dissolving block, or bacteria carried on an engineered particle, for a customer to dose into a wastewater system. Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet and Drylet each describe, on their own websites (September 2026), their own version of that approach. This page sets all eight beside DRP Accelerator, an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater, in one place, with a link to a full page on each.

Eight companies add organisms to wastewater. DRP Accelerator feeds the bacteria already there.

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.

Companies That Add Bacteria to Wastewater

A search for companies that add bacteria to wastewater turns up manufacturers of packaged biological products: bacterial, fungal or enzyme cultures grown or fermented, then sold as a liquid, a powder, a tablet, a dissolving block, or bacteria carried on an engineered particle, for a customer to dose into a lift station, a lagoon, a tank or a collection line. Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet and Drylet are eight of them, each with its own catalog, its own named products and its own way of describing what it sells. Every fact about each company on this page comes from that company’s own website, read in September 2026, and stated in its own terms, with a full comparison page linked for the ones that want more detail.

The One Difference

Set beside each other, the eight companies share one trait: every one of them adds something to the water that was not there before, whether that is a bacterial strain, a fungal culture, an enzyme, a nutrient blend, or bacteria seeded onto a manufactured carrier particle. DRP Accelerator adds none of that. It is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater. With that oxygen available, the bacteria already present stop drawing it from sulfate, the reaction that produces hydrogen sulfide, so the gas is not formed in the first place rather than treated, bound or digested after it already exists. The same oxygen supports the aerobic bacteria already on site as they digest fats, oils, grease and organic sludge, work an oxygen-starved system leaves undone. Nothing is left behind once that work is done: the compound is consumed as the bacteria use its oxygen, and no chemical additives remain downstream. It is dosed as far upstream as water and power allow, as a continuous drip, and run as a monthly measured service built around a baseline reading and follow-up readings, rather than a packaged product bought once and dosed by hand.

Where One of These Companies May Be the Better Fit

All eight of these companies are established wastewater treatment suppliers with their own product catalogs, and a fair comparison says so before it says anything else. A site that wants one manufacturer’s catalog spanning several problems and markets under a single name, rather than a single monthly service, is a reasonable candidate for one of them. A plant working through an ammonia or nitrification upset, where the specific bacteria capable of that job are missing from the system rather than merely short of oxygen, is often better served by a company selling a named nitrifying strain than by a program that only changes the oxygen available to whatever population already lives there. And a small, easily accessible tank that just needs a low-cost, low-commitment trial, a bagged, bottled or tableted product tried once and stopped without equipment left behind, is a reasonable place to start with one of these eight rather than with a continuous program. None of that changes what each company adds to the water; it only says where that addition is the better first step for a given system.

Eight Companies That Add Bacteria to Wastewater, Side by Side

Company	What is added	Form and delivery	Markets it names	Distributor or maker	The question to ask

How to Read This Table

Every row states what the company’s own website says about its own product, as of the date at the top of this page, in that company’s own words rather than ours. None of the eight is described here as better or worse, only as what it adds, how it is delivered, which markets it names, and whether it sells direct or mostly through distributors and dealers. The last column is the one worth spending time on: it names the specific condition each option is built to answer, so the fit can be checked against the system in front of you rather than against a company name. A full page for each company, linked from its row, carries the detail this table leaves out.

Summary

Eight companies, Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet and Drylet, each add bacteria, fungi or enzymes to a wastewater system, in forms ranging from bulk liquid to a dissolving block to bacteria carried on an engineered particle, as their own websites describe them.
DRP Accelerator adds none of that. It is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater, so hydrogen sulfide is not formed and fats, oils, grease and organic sludge are digested by the aerobic bacteria already present, with the compound consumed and no chemical additives left downstream.
A large product catalog, a named nitrifying strain for an ammonia upset, or a low-cost bagged, bottled or tableted trial for a small tank each point toward one of these eight companies; a lift station, force main or lagoon that needs an upstream, continuous, measured program points toward DRP Accelerator.

COMMON QUESTIONS

Straight answers.

What do these companies add to wastewater?+

Veolia Water Technologies, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Brenntag, Aster Bio, Bio-Green Planet and Drylet each describe, on their own websites, products built around bacteria, fungi or enzymes added to a wastewater system, packaged as a liquid, a powder, a tablet, a dissolving block, or bacteria carried on an engineered particle.

Is DRP Accelerator a bacteria additive like these companies sell?+

No. DRP Accelerator adds no bacteria and no enzymes. It is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater, so hydrogen sulfide is not formed and the compound itself is consumed as the bacteria use its oxygen.

When is one of these companies the better fit than DRP Accelerator?+

A site that wants one manufacturer's catalog across several problems and markets, a plant recovering from an ammonia or nitrification upset that needs a named nitrifying strain, or a small, accessible tank that just needs a low-cost trial are each usually better served by one of these eight companies than by a continuous, measured program.

Are Veolia, Microbial Discovery Group, EnviroZyme, Ecological Laboratories, Aster Bio, Bio-Green Planet and Drylet distributors or manufacturers?+

Each is a manufacturer, as its own website describes it. 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, EnviroZyme and Aster Bio describe direct sale alongside a sales team or distributor partners. Bio-Green Planet names several channels without indicating any one is primary: direct sale, distributors, and OEM and private-label partners.

Does any of these eight companies prevent hydrogen sulfide before it forms?+

Their own websites describe their bacteria, fungi and enzyme products working on organic material, ammonia, odor compounds or a targeted pollutant once conditions in the system support that activity. DRP Accelerator acts earlier: with usable oxygen available, the bacteria already present stop drawing it from sulfate, the reaction that produces hydrogen sulfide, so the gas is not formed in the first place.

What question should I ask about my own system before choosing between these options?+

Ask whether the bacteria capable of solving the problem are already present in the system and only short of oxygen, or whether a specific population or pollutant-degrading capability is missing entirely. The first points toward continuous oxygen dosing; the second points toward one of these eight companies' named products.
