DRP Accelerator vs the Aeration Equipment Makers: the Oxygen That Reaches Where Blowers Cannot

Search for aeration equipment makers and six names come up again and again: Xylem, Aqua-Aerobic Systems, Environmental Dynamics International, Parkson Corporation, Aeration Industries International and Grundfos, each building blowers, diffusers or mechanical aerators for a basin, an oxidation ditch or a lagoon, in its own words, on its own website, checked September 2026. The fundamental issue with aeration as a method is a scientific limitation: water holds only a small amount of dissolved oxygen no matter the design, bubble size or power behind the equipment moving air through it, and that ceiling is what the bacteria in that basin are limited to, wherever the equipment reaches at all. Our compound carries oxygen past that ceiling, into force mains, wet wells, sludge blankets and lagoon bottoms no blower or diffuser reaches, running on power like a light bulb and fitting into any treatment plant design. This page sets all six makers beside DRP Accelerator in one table, and the addition case is the point of the whole page: we never ask anyone to shut off a blower, we ask them to add oxygen upstream of it, where it cannot go.

Six companies build blowers, diffusers and mechanical aerators for a basin, a ditch or a lagoon. We carry oxygen to the force mains, wet wells, sludge blankets and lagoons those blowers cannot reach.

Water holds only a small amount of dissolved oxygen no matter the design, bubble size or power of the equipment moving air through it.
Diffused aeration equipment adds air through diffusers mounted in a basin; mechanical surface and jet aerators add oxygen by spraying, pumping or churning water at or below the surface.
Aeration equipment adds oxygen only where its air, spray or jet physically reaches inside a basin, ditch or lagoon.
Force mains, wet wells, sludge blankets and lagoon bottoms commonly sit downstream or below any aeration equipment a system runs.
An inorganic compound that carries usable oxygen on the molecule is available anywhere the compound travels, including where blowers, diffusers and mechanical aerators do not reach.

Peter Flowers puts the aeration argument in one line: the fundamental issue is a scientific limitation. Water can only hold a small amount of dissolved oxygen no matter the design, the bubble size or the power behind the equipment moving air through it, and that ceiling is what the bacteria in the basin are limited to, wherever the equipment reaches at all. A blower feeding fine bubble diffusers, a mechanical surface aerator spraying basin water, or a jet aerator pumping and mixing a tank, every one of them only adds oxygen where its air, spray or jet physically arrives inside the basin, ditch or lagoon it was built for. A force main upstream of the plant, a wet well, a sludge blanket resting on the basin floor and a lagoon bottom below where the mixing reaches commonly sit outside that range, no matter how well the equipment inside the basin performs. Our compound is different in kind: it carries usable oxygen on the molecule itself, so it travels with the water into those same reaches instead of waiting for a blower to push air to them. Power to run it is minimal, closer to a light bulb than a compressor, and it fits into any treatment plant design or collection system without a redesign. The figures behind how much oxygen water can hold, and how far past that our compound reaches, are on our technology page.

Xylem: Sanitaire diffused aeration

Xylem’s Sanitaire brand builds fine and coarse bubble diffusers and membrane diffused aeration systems for municipal and industrial wastewater, installed in aeration basins, aerated grit chambers, sludge holding tanks and digesters, channel aeration and mixing systems, and Bioloop oxidation ditch plants, as its own site describes. That equipment does what a diffuser can do: put air into the basin it is mounted in. DRP Accelerator carries oxygen on the compound itself, so it reaches the force main and wet well upstream of that basin, and the sludge blanket on the basin floor the bubbles pass over, without a diffuser grid of its own.

Aqua-Aerobic Systems: Aqua-Jet surface aerators

Aqua-Aerobic Systems sells the Aqua-Jet mechanical surface aerator, which pumps basin water up through a volute and disperses it through a diffusion head in a spray pattern, installed in activated sludge basins, SBRs, MSBRs, extended aeration, aerobic digesters, sludge holding and equalization basins, per the company’s own site. The spray transfers oxygen and mixes the basin at the same time. DRP Accelerator needs no basin to spray into; it carries oxygen upstream of the basin, into the collection system the Aqua-Jet never touches.

Environmental Dynamics International: FlexAir and CoarsAir diffusers

EDI manufactures FlexAir and CoarsAir fine and coarse bubble diffused aeration systems, installed worldwide in treatment basins and tanks, as wastewater.com describes. The diffuser grid and membrane choice decide how evenly oxygen spreads across the basin floor it serves. DRP Accelerator does not need a grid sized to a basin; the oxygen travels with the water into whatever sits upstream of that basin.

Parkson Corporation: VariOx, RetrievOx and Biolac

Parkson sells the VariOx jet aeration system, the RetrievOx diffused fine bubble aeration system, and the Biolac extended aeration system with a floating aeration chain, installed in activated sludge basins, holding tanks, lagoons, and lined earthen basins built or retrofitted for Biolac, by Parkson’s own account. Each system is built around a basin or lagoon the equipment sits in or floats on. DRP Accelerator carries oxygen to the collection system feeding that basin, a reach none of Parkson’s aeration equipment is built to cover.

Aeration Industries International: Aire-O2 Triton

Aeration Industries International built the Aire-O2 Triton surface aerator and mixer line before Newterra acquired the company; the Triton 2.0 now runs under the Newterra brand as a surface-mounted process aerator and mixer that combines aeration and mixing in one unit, shown installed in oxidation ditches and open-air treatment basins and ponds, per Newterra’s own site. It reaches the water its float or mount sits in. DRP Accelerator reaches the force main or lift station upstream of that ditch or pond, where no floating unit is placed.

Grundfos: jet aeration and pumps

Grundfos sells a range of submersible wastewater pumps, a grinder pump for raw sewage, control panels, and an aeration product line alongside its pumps, sold for wastewater, drainage and tank-filling applications in wet wells, lift stations and tanks, as the company’s own site describes. Its pumps move water through the system; its aeration line adds oxygen where it is installed. DRP Accelerator adds oxygen to the water itself, so it is available in the stretch of force main between one Grundfos pump and the next, where nothing else is adding it.

DRP Accelerator: oxygen where the blowers cannot go

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 blower, a diffuser or a mechanical aerator can only put oxygen into the basin, ditch or lagoon it is built for; a force main, a wet well, a sludge blanket and a lagoon bottom outside that reach get none of it. Give the bacteria in those reaches a supply of usable oxygen and they take it before they take it from sulfate, so the sulfide that becomes hydrogen sulfide gas never gets made, and the same bacteria work through fats, oils, grease and settled solids an oxygen-starved stretch of pipe leaves 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 aeration decision

Where does the water sit before it reaches any blower, diffuser or mechanical aerator, and does anything add oxygen to it there?
Does the equipment’s air, spray or jet reach the full depth of the basin, including the sludge blanket on the floor, or only the water above it?
Is the complaint coming from inside the basin the aeration equipment serves, or from a force main, wet well or lagoon upstream of it?
What does it cost to add reach, in capital and installed equipment, versus a service that carries oxygen on the water itself?
Does adding reach mean a new basin or a new blower, or can oxygen travel upstream without a new structure to house it?
How is the result measured: a spec sheet for oxygen transfer inside the basin, or a baseline set before the first change and readings taken against it everywhere the oxygen now reaches?

Keep the blowers, add DRP Accelerator upstream

We never ask a site to shut off a blower, a diffuser or a mechanical aerator, and none of the six makers on this page describes equipment we would ask you to remove. Adding DRP Accelerator upstream of plant aeration is the whole point of this page: we take load off the aeration equipment already running by preventing hydrogen sulfide and digesting fats, oils, grease and sludge before the water ever reaches the basin, and we reach the force mains, wet wells, sludge blankets and lagoon bottoms none of that equipment touches. 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 the blower, diffuser or aerator that keeps running exactly as it does today. We set a measured baseline before changing anything else, then take follow-up readings against it on a schedule that matches your tank size. Gas monitors and confined-space procedures at a lift station or wet well stay in place regardless of what the readings show.

Ask every vendor for the same page

Ask any of these six makers, and ask us, for the same page: what the equipment adds, where it physically reaches, and where it stops. A fair vendor answers all three for its own equipment, not only the basin it was built for. We will show you the program on your own system: where we would set the dosing point upstream of your aeration, 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 aeration equipment?+

No, it is the addition that reaches where aeration cannot, and it never replaces plant aeration. Xylem, Aqua-Aerobic Systems, Environmental Dynamics International, Parkson Corporation, Aeration Industries International and Grundfos each build blowers, diffusers or mechanical aerators that add oxygen inside a basin, an oxidation ditch or a lagoon, described on their own websites as of September 2026. That equipment does real work wherever its air, spray or jet physically reaches. Water can only hold a small amount of dissolved oxygen no matter how that equipment is designed, so a force main, a wet well, a sludge blanket or a lagoon bottom the blower does not reach stays short of oxygen regardless of how well the plant's aeration basin runs. DRP Accelerator carries usable oxygen on the molecule, past that ceiling and into those same reaches, added upstream of the aeration equipment that keeps running.

What is the main difference between DRP Accelerator and aeration equipment?+

Aeration equipment adds oxygen by moving air or water inside a basin, a ditch or a lagoon, so it only reaches where the blower, diffuser or aerator physically puts its air or spray. DRP Accelerator carries usable oxygen on the compound itself, so it travels with the water into a force main, a wet well, a sludge blanket or a lagoon bottom that sits beyond where any blower reaches, and it runs at a fraction of the power of a blower, closer to a light bulb than a compressor.

Where does aeration equipment fall short?+

Not in its design. Every maker on this page builds equipment that transfers oxygen efficiently where it is installed, by their own websites' account. The limit is physics and location, not any one maker's engineering: water can only dissolve a small amount of oxygen regardless of bubble size or blower power, and a blower, diffuser or mechanical aerator only adds that oxygen where its air or spray reaches inside the basin it is built for. A sewer line, a wet well, a sludge blanket or a lagoon bottom the aeration equipment does not reach gets none of it, whatever the equipment achieves inside the basin.

Do we have to stop using our aeration equipment to start DRP Accelerator?+

No. We dose DRP Accelerator upstream of whatever aeration equipment already runs, whether that is a blower and diffuser system, a mechanical surface aerator or a jet aerator and pump, and set a measured baseline before changing anything else. Nothing has to come out.

Can DRP Accelerator run at the same time as our aeration equipment?+

Yes. Aeration equipment adds oxygen inside the basin it is built for, and DRP Accelerator carries oxygen upstream of that basin and into the reaches a blower or aerator cannot touch, so running both at once does not conflict. Many sites keep every blower and diffuser in service exactly as it runs today.

What happens to our aeration equipment once DRP Accelerator is running?+

It keeps running. We never ask a site to shut off a blower, a diffuser or a mechanical aerator; plant aeration stays in service. What changes is the load reaching it: with usable oxygen already working upstream, less organic material and less hydrogen sulfide arrive at the basin, so the same aeration equipment has less to do to hit the same result.

Is Waste Water Innovations affiliated with Xylem, Aqua-Aerobic Systems, Environmental Dynamics International, Parkson Corporation, Aeration Industries International, Newterra or Grundfos?+
