Six options side by side

Option What it adds Acts before or after H2S forms What stays downstream Works on FOG and sludge Where it fits
Bacteria additives An outside bacterial culture After: needs oxygen or a niche to establish before it works The added culture, competing with the native population Some formulations, if they establish A small, accessible tank that wants a low-cost, one-time trial
Enzyme products Manufactured enzymes After: breaks down existing material, does not stop sulfide from forming Spent enzyme residue FOG mostly, limited effect on the gas A grease-heavy line where the gas is not yet the main complaint
Iron salts An iron compound After: binds sulfide once it exists Iron compound requiring removal or settling No, gas only A site that needs a fast odor knockdown while a longer fix is arranged
Nitrate products Nitrogen compound Before: gives bacteria an alternate oxygen source to sulfate Added nitrogen No, gas only A force main with the flow and dosing access to sustain nitrate addition
Aeration Air, dissolved oxygen Before, where it physically reaches Nothing added, but an ongoing blower and energy cost At the plant, not upstream A treatment plant with the blower capacity and access aeration needs
Scrubbers and masking agents Chemical scrubbing media or fragrance After: treats the gas or the smell once it is in the air Spent scrubbing media or fragrance residue No An enclosed space where the air, not the water, is the problem
DRP Accelerator Usable oxygen for the bacteria already there Before: hydrogen sulfide is not formed Nothing; the accelerator is consumed as the bacteria use it Yes, both Any collection system, lift station, force main or lagoon, on its own or added upstream of whatever is already running

No row on this table is wrong for every site. A lift station with an odor complaint today may still need an iron drum on order while a dosing point for DRP Accelerator is surveyed. A plant with room in its aeration basins may only need help upstream, where blowers cannot go. Read the table for where each option sits, then read the page closest to your problem for the full case, and remember that DRP Accelerator drops in upstream of any row on this table without removing it first.

Read the full comparisons

  • Bacteria additives: DRP Accelerator is the stronger choice for any lift station, force main or lagoon bigger than a single accessible tank, feeding the bacteria already there instead of adding more from a bag or a bottle.
  • Enzyme products: DRP Accelerator is the stronger choice where H2S matters as much as the grease, since native bacteria with oxygen digest FOG in place instead of only cutting it apart.
  • Iron salts: DRP Accelerator is the stronger choice for the ongoing problem, keeping hydrogen sulfide from forming at all rather than reacting with it after it already has, on its own or added upstream of an iron dose already running.
  • Nitrate products: DRP Accelerator is the stronger choice for a site that cannot sustain nitrogen dosing, preventing hydrogen sulfide the same way nitrate does, without adding nitrogen downstream.
  • Aeration: DRP Accelerator is the stronger choice upstream of the plant, carrying oxygen into the force mains, wet wells and sludge blankets aeration cannot reach.
  • Scrubbers and masking agents: DRP Accelerator is the stronger choice for the wastewater itself, preventing hydrogen sulfide from forming there instead of treating it in the air once it already has.

Named suppliers, one page each

The nine companies below add bacteria to wastewater, and each is an established supplier. Every page states what that company’s own website says about its product, then says plainly why DRP Accelerator is the stronger choice for most systems. Start with the side-by-side page if you want all nine in one place.

  • All nine side by side: one table, one row per company, and the DRP Accelerator row last so the eye lands on it.
  • Veolia Water Technologies: adds bacteria, fungi, enzymes and nutrient supplements through its BioPlus line. DRP Accelerator adds none of that, only usable oxygen for the bacteria already in your water.
  • Microbial Discovery Group: adds Bacillus bacteria strains and a nutrient blend through Biotifx. DRP Accelerator feeds the bacteria you already have instead of adding a new strain that has to establish.
  • EnviroZyme: adds fermented bacterial blends built for nitrification, FOG and odor jobs. DRP Accelerator prevents the hydrogen sulfide those blends work around, before it forms.
  • Ecological Laboratories: adds packaged MICROBE-LIFT bacterial cultures and a separate micronutrient product. DRP Accelerator needs no packaged culture, since the bacteria are already in your wastewater.
  • Brenntag: distributes a catalog of added bacteria, enzymes, nutrients and a floc-control chemical under Arkea and ProBlend. DRP Accelerator is a single measured service, not a catalog to dose by hand.
  • Aster Bio: adds named microbial blends isolated for specific pollutants, with enzymes and surfactants in some products. DRP Accelerator puts oxygen to work on the bacteria already equipped for the job that is already there.
  • Bio-Green Planet: adds Bacillus bacteria blends and enzymes across several packaged product lines. DRP Accelerator runs as one continuous program instead of a rotation of packaged products.
  • Drylet: adds bacterial cultures embedded in engineered porous particles. DRP Accelerator carries oxygen to the bacteria already on site, with no particle or carrier to dose.
  • REX-BAC-T: sells bulk powder, liquid and solid bacteria and enzyme formulations under named product lines such as BP-1200 and EP-1201. DRP Accelerator feeds the bacteria already living in your wastewater instead of dosing a new culture by the pound.

Aeration and chemical suppliers, all in one

  • Aeration equipment makers: DRP Accelerator is the stronger choice as the addition upstream of any blower, diffuser or mechanical aerator, carrying oxygen into the force mains, wet wells and sludge blankets that equipment is not built to reach.
  • Chemical suppliers: DRP Accelerator is the stronger choice for the site that wants nothing left to remove, since it is completely consumed in the wastewater instead of leaving iron, nitrogen, phosphorus or calcium behind.
