Non‑filamentous bulking is one of the most misunderstood causes of poor settling, high viscosity, and MBR fouling — and LB‑EPS is almost always at the center of it.

Winter is coming — and so are the biology shifts in your plant.
As temperatures drop, extended SRT protects nitrifiers but also encourages slow-growing filaments like Nocardia and M. parvicella — the culprits behind cold-weather foaming.

With Aster Bio’s MCA platform, operators gain real-time insight into microbial changes, enabling proactive adjustments to SRT, wasting, aeration, and FOG management before winter conditions set in.

A well-designed wastewater operational dashboard gives operators one trusted view of loading, biological treatment, solids handling, and effluent compliance. By limiting the display to actionable KPIs, standardizing data inputs, defining visual alert thresholds, and emphasizing trends, plants can detect process shifts earlier and respond before performance or permit compliance is affected.

As temperatures drop, biology changes.

Fall marks a critical handoff in activated sludge systems—summer organisms slow while cold‑tolerant populations take over. In my latest post, I outline how operators can anticipate this shift to protect settling and nitrification before performance dips.

Foaming filaments are one of the most frustrating — and most predictable — biological problems in activated sludge systems. The two major culprits are the Nocardia type actinomycetes (including Gordonia) and Microthrix parvicella. Both organisms create stable, persistent foam, but they thrive under slightly different conditions.

Stop guessing what's driving your plant's biology and start using hard molecular data to control it.

Whether you're working to improve plant stability, control stubborn filaments, or optimize nutrient removal, this walkthrough shows how Environmental Genomics turns biology into a actionable asset for operators.

Unlocking wastewater biology isn’t about guesswork — it’s about using molecular data to understand exactly what’s happening in the plant. MCA testing connects 16S sequencing, bioinformatics, and functional‑group analytics to turn complex microbial data into clear operational intelligence.

Aster Bio’s Environmental Genomics MCA test is built on a simple idea: wastewater treatment is driven by biology, so the best way to optimize a plant is to understand that biology at a molecular leve…

Environmental genomics helps us understand wastewater biology — but only if we interpret genetic potential through the lens of real‑world operating conditions. In this post, I break down why genotype alone doesn’t predict system behavior, and why phenotype — the biology’s actual response under stress, load, and competition — is what truly drives performance.
