Two starting points
Aeration is the practice of raising dissolved oxygen in wastewater by mechanical means: a blower pushing air through diffusers at the bottom of a basin, a surface aerator splashing water into the air, a mixer keeping a basin turned over, or air or oxygen injected directly into a pipe. It is the standard method inside nearly every activated sludge treatment plant, where the aeration basin is the heart of the process, and at many aerated lagoons where blowers or surface units keep the pond from turning anaerobic. Aeration equipment is built, sized and maintained for the specific tank, basin or lagoon it serves, and where the water sits in a space an operator can walk to, wire and service, it is a proven, well-understood tool with decades of engineering behind it. None of that changes what a blower can physically do: it can only push air or oxygen into the water it is plumbed into, at whatever rate its motor and diffusers allow.
DRP Accelerator takes a different approach. It is an inorganic compound that carries usable oxygen to the bacteria already living in the wastewater, and we add no bacteria and no enzymes of our own. Because the oxygen is carried on the compound itself rather than dissolved into a headspace of air, it travels with the water into the anaerobic zones a blower was never built to reach: the force main, the wet well, the sludge blanket at the bottom of a lagoon. The same bacteria that would otherwise strip oxygen from sulfate, producing the hydrogen sulfide that causes odor and corrosion, use this oxygen instead, so the gas is prevented rather than captured after the fact. See our guide on why wastewater bacteria need oxygen for the full order bacteria draw on before they ever reach sulfate.
What decides the choice between the two comes down to four things: what each one actually adds to the water, when it acts relative to the moment hydrogen sulfide forms, what stays behind once the work is done, and what it costs to run in capital and handling terms. A system rarely has to pick only one; most municipal systems end up running some form of both, at different points along the same flow.
At a glance
| Factor | DRP Accelerator | Aeration |
|---|---|---|
| What is added | Usable oxygen carried on an inorganic compound; no bacteria or enzymes added | Air or oxygen mixed directly into the water by a blower, diffuser, surface aerator or mixer |
| When it acts | Before hydrogen sulfide forms, wherever the dosed water travels | Only while the equipment is installed and running |
| What stays downstream | Nothing; the compound is consumed as bacteria use its oxygen | Whatever the equipment does not reach simply keeps running low on oxygen |
| Where it reaches | Force mains, wet wells, lift stations and sludge blankets, not only the basin | Only the tank, basin or lagoon the equipment is installed in |
| FOG and sludge | The same aerobic bacteria digest fats, oils, grease and organic sludge once oxygen is available | Raises dissolved oxygen; does not target FOG or sludge directly |
| Capital and handling | No capital purchase; a monthly service we run and measure | Blowers, diffusers, surface aerators or mixers, installed and maintained on site |
| How it is measured | Baseline readings taken first, then compared against the same readings over time | Dissolved oxygen readings in the basin, plus equipment runtime and maintenance logs |
This describes aeration in general, the blowers, diffusers, surface aerators and mixers used across activated sludge plants and lagoons, not any single manufacturer’s equipment. Specifications and costs vary by site; confirm details with your equipment supplier.
That table is most of the decision. If it already reads your way, contact us and we will show you the program on your own system.
Where DRP Accelerator is the stronger choice
- A scientific ceiling no blower can outrun. Water holds only a small amount of dissolved oxygen no matter the aerator’s design, bubble size or power, and that ceiling is all the bacteria get from mechanical aeration alone. Our oxygen is available well beyond what water can dissolve, the equipment draws power like a light bulb, and it fits into any treatment plant design or system already in place. The figures are on our technology page.
- Prevention instead of a bigger blower. Aeration adds oxygen and hopes the bacteria reach it before they turn to sulfate; DRP Accelerator carries the oxygen straight to the bacteria, so the reaction that produces hydrogen sulfide has nothing left to run on, upstream of any basin.
- Nothing added that stays behind. We add no bacteria, no enzymes and no equipment that has to sit in the water permanently; the compound itself is used up as the bacteria draw on its oxygen, so there is nothing left downstream to account for.
- FOG and sludge digested by the same bacteria. The oxygen we deliver feeds the same aerobic bacteria that break down fats, oils and grease, work aeration alone does not do no matter how well it raises dissolved oxygen in the basin it serves. A municipal plant sludge reduction project measured that digestion on a fixed survey grid.
- Reach where aeration cannot go. A lift station wet well or a force main under pressure has no blower or diffuser inside it; DRP Accelerator’s oxygen travels there because it moves with the water rather than with installed equipment, and one Texas lift station shows what that looks like in practice.
- No capital purchase, a monthly service we run and measure. There are no blowers to buy, size or maintain; we review the site, calculate a dose using the AerobicShift dosing approach, and run it as a service with readings taken against a baseline.
- Works in anaerobic and aerobic water alike. Aeration only helps water it can reach and keep oxygenated; DRP Accelerator’s oxygen is useful to bacteria whether the water around it is anaerobic or aerobic, which other sites have put to use well upstream of any aeration basin.
Where aeration still has the edge
Aeration is well-understood engineering, already installed and staffed at nearly every activated sludge plant, and a facility with an engineered basin, the blower capacity to run it and staff to maintain it already has the right tool in place. A lagoon with reliable power and a budget for diffusers or surface units is also a reasonable candidate for aeration on its own, particularly where the goal is simply keeping the surface water from turning anaerobic. Anywhere the water sits in a tank, basin or lagoon an operator already controls, with the power and capital to run equipment, aeration is a fair first option to weigh before looking upstream. See our biological treatment optimization page for how that reasoning plays out at a plant already running near its permit limit.
Where DRP Accelerator pulls ahead is everywhere that ownership stops: the force main, the wet well and the sludge blanket at the bottom of the basin the blower cannot reach. Aeration is the right tool for the basin it was engineered for; it was never built to solve a problem that starts miles upstream of that basin’s walls.
Already running aeration? Add DRP Accelerator upstream
Nothing about the existing aeration has to be removed, shut down or changed before we start. We dose DRP Accelerator upstream of the aeration basin, in the collection system, a lift station wet well or the lagoon itself, set a baseline against current readings, and measure from there. The aeration basin keeps running exactly as designed; DRP Accelerator is not a substitute for engineered equipment already doing its job, and we do not ask anyone to turn the blowers down or take anything out. What changes is how much work is left for that equipment to do, because the water arriving at the basin already carries a lighter load, less BOD, less FOG and smaller solids, from bacteria that had usable oxygen in the collection system on the way in. That lighter load shows up in the same dissolved oxygen and loading readings the plant already tracks, so the change is something the operator can read for themselves rather than take on faith. Gas monitors and confined-space entry procedures stay in place throughout, on the same schedule they were already on; nothing about how a lift station or a wet well is entered and worked in changes because DRP Accelerator is now dosed upstream of it.
How to decide
- Find where the oxygen actually runs out. Walk the system from the furthest upstream point toward the plant and mark where dissolved oxygen disappears: that is where hydrogen sulfide starts forming, and it is rarely inside the aeration basin itself.
- Ask what each option adds to the water, and what, if anything, stays behind once it has done its work. An added compound that is consumed is a different proposition than equipment that keeps running indefinitely.
- Ask what happens to FOG and sludge, since raising dissolved oxygen in a basin and digesting organic solids upstream of it are not automatically the same job.
- Ask what it costs to run in capital and handling terms, and how the result gets measured, a blower’s electricity draw and maintenance log against a monthly service and a baseline reading taken before dosing starts.
Ask both vendors for the same page
Ask an aeration equipment vendor to walk the system with you to the oldest, hardest-to-reach point you have, a force main, a wet well, a lift station, and say what happens to the water there. Ask us the same question. We will show you the program on your own system before you commit to anything: the dosing point furthest upstream that water and power allow, the baseline we take before dosing starts, and the readings we measure against it afterward. Bring both answers back to the same table and compare them side by side rather than taking either vendor’s word for it alone. Contact us and we will start there. We say all of this about our own product in public, not only in a room with one customer, because the case for DRP Accelerator holds up whether or not aeration is already running on the same site.
