If a treatment plant or treatment pond is struggling to meet compliance on its NPDES (National Pollutant Discharge Elimination System) permit requirements for BOD5, TSS and/or Percent Removal, then BiO3 Bioaugmentation may be a solution, or at least an interim solution to the problem.

BiO3 Bioaugmentation Treatment Impact

The injected BiO3 microbes beneficially impact the digestive effectiveness and efficiency of the wastewater collection system and the treatment plant (pond) in several ways:

The Current Collection System Digestion is not Effective -- Of course digestion of the organics in the wastewater begins in the collection system. In many cases the wastewater is in the collection system longer than it is in the treatment plant processes that are usually aerobic processes.

However, in most cases the digestion in the collection system is currently ineffective. This is because the microbes supplied by nature from the human gut are slow-growing anaerobes that are not effective in aerobic treatment processes. (It is only in the force mains with long retention times that the SRB’s [Sulfate-Reducing Bacteria] really grow.) And, in many cases the digestive efficiency in the collection system is further degraded by the chemicals dumped into the wastewater for H2S or odor control purposes.

More Effective, Efficient Pretreatment Digestion – The impact of a high quantity of microbes designed to act as a digestion team injected early in the collection system will improve both the effectiveness (doing the right job) and the efficiency (doing the job right) of the digestion in the collection system.


BiO3 Bioaugmentation Microbes consist of Multiple Strains & Synergistic omposition

Multiple strains of aerobic and facultatively anaerobic microbes are selected for their compatible, symbiotic metabolic pathways, which metabolize (digest) CBOD (Carbon Biological Oxygen Demand), BOD (Biochemical Oxygen Demand), and TSS (Total Suspended Solids). This means that the combination of these strains will successively break down and digest the waste in both aerobic and anaerobic conditions to a far greater degree than the same quantity of only one of the microbe strains (especially if that one microbe is a SRB). They’re a team, not one individual superbug.

Less SRB’s Enter the Treatment Plant – In the treatment plant SRB’s become part of the pollutant removal problem rather than part of the solution.

Through competitive exclusion, the BiO3 microbes will replace the SRB’s as the predominate biofilm species on the interior surfaces of the collection piping walls. Since about 80% of microbe growth in the collection system comes from the biofilm, this means with less biofilm wall space there will be fewer and fewer SRB’s and less sulfides (since SRB’s create sulfides) in the wastewater to be removed in the treatment plant.

Treatment Plant Performance is Enhanced –Treatment Plant performance is enhanced several ways:

The influent waste is already partially broken-down by the BiO3 microbes so it is more conducive for treatment than before. Therefore, it is easier to remove.

BiO3 microbes, which are now great in number, continue to function in the treatment plant aerobic and anaerobic digestion processes. The microbes are young and robust and join the plant biology in the digestion task. Also, because they are in constant supply, the plant biology remains young. It is accepted by the wastewater treatment industry that the addition of fresh microbes in the treatment plant influent will improve the plant performance and stabilize plant operation. Recovery from treatment plant biology ‘wash-outs’ is also much quicker.

Primary basin/clarifier settleability is increased. There are several possible reasons for this. 1) The injected microbes have degraded the grease/oils so there are less grease/oils in the WW to float to the surface. 2) The injected microbes outcompete the filamentous bacteria for food substrates so there is less bulking. 3) There are fewer dead SRB’s. According to some sources, live microbes settle out faster than dead microbes.

To observe an actual data trend, see chart below.

Pollutant (BOD5, TSS) discharge is reduced. The influent waste is already partially consumed by the BiO3 Bioaugmentation microbes so it is more conducive for treatment than before. Therefore, it is easier to remove.

With fewer SRB’s and dead microbes with which to contend and with more microbes assisting in the digestive process, more of the organics and pollutants will be converted to gas (i.e. carbon dioxide, hydrogen, methane and nitrogen) thereby increasing the digestion efficiency of the plant. Less pollutants are discharged in the effluent wastewater.

To observe an actual data trend, see chart below.

The Plant Percent Removal is increased. As described above the influent waste is already partially broken-down and partially digested by the BiO3 Augmentation microbes in the collection system. But the influent BOD ppm and TSS ppm are not reduced all that much. Of course the reason being that the high BiO3 Augmentation microbe growth shows up in the BOD and TSS influent readings. But with increased BOD and TSS removal from the influent, as shown above, the Percent Removal increases.

To observe an actual data trend, see chart below.

Hence, the biological impact of the BiO3 Bioaugmentation is positive and in many situations it can put the treatment plant over the top from a performance standpoint and, thereby, bring the plant into compliance.
