Winning the Bacteria Battle in Wastewater Treatment

As wastewater facilities age, capacity and quality problems arise. Wastewater treatment plants (WWTP) require upkeep and reinvestment to maintain efficacy and efficiency, and these improvements frequently require substantial capital expenditure (CAPEX). While traditional WWTP improvements demand expensive infrastructure and equipment investments, innovative microbiological technology reduces or eliminates CAPEX demands, enhances the quality of output, and radically improves plant performance.

To understand the extensive benefits of microbiological technology vs. traditional high-CAPEX development, think in terms of the constant bacteria battle within wastewater facilities.

The problem with CAPEX

When wastewater infrastructure reaches capacity, municipalities often leap to the “obvious” approach of expansion — which usually requires extensive CAPEX.

Physically expanding capacity is a resource-heavy endeavor. With costs adding up for construction materials and additional labor, CAPEX can quickly climb into the millions. Even smaller WWTPs have extensive budget demands associated with plant renovation, expansion, and modernization. There are also ongoing expenses that arise from expanded infrastructure, including operational (e.g., energy) costs and future maintenance expenditures.

In one example of a five million gallon-per-day (gpd) WWTP, the initial estimate to upgrade organic and hydraulic overloading — specifically to improve aeration, dissolution, and clarification (only a portion of the treatment process) — amounted to more than $700,000 in CAPEX costs, or $175 per 1,000 gpd of incremental upgraded capacity. This estimate did not include contingencies for engineering design, bonding, or construction supervision.

The unfortunate downside of an improvement like this is that it represents a static solution to a dynamic problem. The bacteria battle is continuous and will continue to push the limits of physical WWTP infrastructure. It’s not a matter of if another upgrade will be necessary in the future, but rather when the next CAPEX hit will arrive — and how long municipalities can stretch their infrastructure.

Bioaugmentation maximizes WWTP capacity

While CAPEX investments increase physical capacity, an advanced microbiological solution maximizes existing WWTP capacity, and creates microbial communities that improve WWT efficiency, with a strategic approach to the bacteria battle. The most effective weapon against indigenous bacteria is — natural, soil-derived, custom trained, and consistently delivered — bacteria.

Traditional treatment approaches rely on forcing indigenous bacteria within the WWTP (e.g., human gut bacteria) to break itself down, which does not occur naturally. Instead, gut bacteria align with pathogenic and parasitic microorganisms to proliferate in the WWT environment. An advanced bioaugmentation system, such as the EBS-Di from EnBiorganic Technologies, uses bacillus soil bacteria to naturally break down organics. This soil-derived microbiology reduces biosolids by effectively targeting indigenous bacteria.

EnBiorganic’s advanced microbe consortiums have a winning record against indigenous bacteria, and its ill effects, including FOG, odor, energy inefficiency, and high CAPEX expansion requirements. Advanced microbiology, delivered as part of a technology as a service (TaaS) model, is a complete result for WWT challenges and the limited municipal budgets struggling to stay ahead of capacity concerns and associated CAPEX.

The bacteria battle

The bacteria battle is ongoing and dynamic, and the solution must be equally so. Advanced microbiology, continuously delivered, is a continuous return on investment for municipalities.

The EBS-Di TaaS model generates, activates, adapts, and dispenses soil-derived bacteria (i.e., bacillus) to reduce biosolids naturally. It’s designed to offset the continuous flow of gut bacteria entering the WWT environment with a continuous delivery of good bacteria.

With its ability to connect to any infrastructure, and adjust to the bacterial profile of any WWTP, the EBS-Di is a strategic advantage in the battle to maximize capacity and optimize results. Bioaugmentation nets municipalities lower energy costs, reduced sludge, FOG, and odor, and with its ability to proliferate throughout the wastewater system, a significant reduction in CAPEX expansion costs. The EBS-Di makes wastewater treatment more effective, efficient, and sustainable — all while providing a higher ROI.

Winning the war on waste

Facilitating more efficient wastewater treatment comes down to winning the bacteria battle. Municipalities can pour millions of dollars into infrastructure expansion with the expectation that their processes will keep up with capacity demands. Unfortunately, it’s a costly, temporary, and losing strategy.

For wastewater treatment success, municipalities need a guaranteed win with an efficient, cost-effective solution. To learn more about the extensive benefits of an advanced microbiological approach to wastewater treatment, visit
