At a 90,000-bird-per-day poultry slaughterhouse in Brazil, continuous Wastewater Treat dosing cut effluent BOD from 860 to 121 mg/L and lifted plant efficiency from 55% to 86% in 90 days, with surface grease and odor eliminated.
| Metric | Before | After 90 days |
|---|---|---|
| Effluent BOD | 860 mg/L | 121 mg/L (86% lower) |
| Plant efficiency | 55% | 86% |
| Surface FOG | Thick cap, blocked oxygen | Eliminated |
| Odor | Strong | Eliminated |
| Flow treated | 2,250 m3/day (8-day HRT) | Stable, in compliance |
The plant treats 2,250 m3 per day of high-strength wastewater from a poultry slaughterhouse running 90,000 birds per day. On paper the system had enough hydraulic retention time, 8 days, to hit its discharge targets. In practice it was in biological treatment failure.
The root cause was a heavy load of fats, oils, and grease. FOG had built into a thick cap across the aeration surface, blocking oxygen transfer, suppressing the microbial community that does the actual treatment, and driving strong odor. Effluent BOD sat at 860 mg/L and overall plant efficiency had fallen to 55%, putting the facility under real compliance pressure. The operator needed to digest the FOG load, restore oxygen transfer, and rebuild performance without rebuilding the plant.
The facility ran a continuous bioaugmentation program using Wastewater Treat (WT), a high-CFU, spore-based blend of wastewater treatment bacteria built for municipal, industrial, and agricultural systems. WT targets BOD, COD, TSS, sludge, and odor, and produces enzymes that break down the fats, proteins, and cellulose that overwhelm a meat-processing waste stream.
Dosed steadily into the treatment train, WT digested the surface FOG, cleared the grease cap off the aeration tank, and restored oxygen transfer so the resident biology could recover. As the microbial community rebuilt, BOD removal climbed and odor fell away, with no major process changes and no new equipment.
Before treatment: a thick FOG layer capped the aeration surface, blocking oxygen transfer and driving strong odor, with effluent BOD at 860 mg/L and plant efficiency down to 55%.
After treatment: FOG and odor eliminated at the source, effluent BOD down from 860 to 121 mg/L (86% lower), and plant efficiency up from 55% to 86% within 90 days.
Within 90 days, effluent BOD dropped from 860 mg/L to 121 mg/L, an 86% reduction, and plant efficiency rose from 55% to 86%. Surface FOG and odor were eliminated at the source, and the aeration tank could once again carry the high-strength load without upsets, bringing the facility back into stable compliance.
Effluent BOD dropped from 860 mg/L to 121 mg/L, an 86% reduction, within 90 days of continuous dosing. Plant efficiency climbed from 55% to 86% over the same period.
Wastewater Treat (WT) is a high-CFU, spore-based blend of wastewater treatment bacteria for municipal, industrial, and agricultural systems. It works on BOD, COD, TSS, sludge, and odor, and produces enzymes that break down the fats, proteins, and cellulose in high-strength waste streams.
Yes. It is built for high-strength, high-grease streams like poultry slaughterhouse and meat processing effluent, where fats, oils, and grease overwhelm conventional biological treatment. This trial ran on a plant handling 2,250 m3 per day from a 90,000-bird-per-day operation.
WT produces enzymes that digest fats, proteins, and cellulose. As the surface FOG cap breaks down, oxygen transfer returns and the biology in the aeration tank recovers, which is what pulls BOD back down.
WT is fed continuously into the treatment train. At this plant the grease cap and odor cleared, BOD fell sharply, and the system reached an 86% BOD reduction and full recovery within 90 days, with no process changes and no new equipment.
Yes. Efficiency here rose from 55% to 86% in 90 days on continuous dosing alone, with no structural changes and no capital equipment added.
