From Microbial Data to Plant Performance: The Science Behind MCA Testing
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 …

Why Paracoccus is Every Wastewater Operator’s Secret Weapon for Nitrogen, Odor, and VFA Control
Often, system stability comes down to functional microbial diversity. If you’re managing fluctuating influent loads, stringent nitrogen limits, or odor issues, there’s one workhorse microbe you want thriving in your …
Sep 2, 2026Using MCA Testing to Stay Ahead of Seasonal Biology Shifts
Municipal systems behave differently as temperatures rise and fall. Even small swings — 2 – 4oC — can shift the balance between AOB, NOB, filaments, and foaming organisms. MCA data …

Why wasting sludge is not optional and is a key control mechanism in wastewater treatment
Wasting is more than a solids-handling task—it one of the primary controls in activated sludge systems. Each wasting decision affects solids retention time (SRT), food-to-microorganism ratio (F/M), microbial selection, oxygen …

Microbial Ecology Is the Operating Manual for Wastewater Treatment
Microbial ecology is not an academic layer added to wastewater treatment and bioremediation — it is the operating basis of the process. Settling, nitrification, denitrification, biological phosphorus removal, foam control, …

Shear, Select, Densify: The Biology Behind Better-Settling Sludge
The Core Idea: Selection Pressure + EPS Remodeling The densification and AGS processes share a simple but powerful ecological principle: If you remove Loosely Bound (LB‑EPS) and retain only biomass …

What looking under the microscope tells you about biological health
Protozoa and metazoa act as living performance indicators. Their presence, abundance, and behavior reflect how well the bacterial community—the true engine of treatment—is functioning. Protozoa Protozoa are typically the first …

Why Bio-P Systems naturally host more Filamentous Bacteria than Conventional Activated Sludge
Wastewater treatment plants with Enhanced Biological Phosphorus Removal (EBPR), operate with anaerobic, anoxic and aerobic zones carefully balanced to maintain vital PAO populations. Microbial Community Analysis (MCA) testing of EBPR …

Why CFU/Gram Is a Misleading Metric for Bioaugmentation Quality
Buyers often reach for CFU/gram as a simple comparison tool. It feels objective, measurable, and easy to put on a spec sheet. But in biological wastewater treatment, CFU/gram is one …

Alkalinity: The Hidden Driver of Stable Nitrification and Denitrification
Alkalinity is the water’s ability to neutralize acids. In wastewater systems, it acts as a biological “buffer,” keeping pH stable as microbes convert ammonia → nitrite → nitrate → nitrogen …

Can Biosurfactants Make Heavy Metal Remediation Cleaner and Smarter?
In-situ biosurfactant generation offers a compelling way to clean heavy-metal-contaminated soils without excavating them or relying on harsh chemical washes. The idea is simple: encourage microorganisms already present in the …

Filamentous Bulking: The Hidden Aeration Energy Penalty in Wastewater Treatment
When talking about filamentous bacteria, the focus is usually on high SVI, poor settling, and clarifier washout risk. Those are real concerns—but they are only part of the story. Filaments …
