A diverse community of bacteria, archaea, protozoa, and fungi acts as a living, dynamic ecosystem responsible for several critical purification processes: Importance to Operations (Stability and Efficiency) Microbial diversity is …
Dec 1, 2025Biological wastewater treatment is powered by microorganisms. Just like us, these tiny workers need a balanced diet to stay healthy and perform their job—breaking down pollutants. Their diet consists of …
Nov 18, 2025In biological wastewater treatment process efficiency relies on the health and stability of the microbial flocs— aggregates of bacteria, adsorbed organics, and inorganics. When these flocs break apart, a problem …
Nov 6, 2025As wastewater professionals, we’re all familiar with the activated sludge process—the backbone of many treatment plants. But one aspect that often flies under the radar until it causes issues is …
Oct 30, 2025Wastewater treatment plants (WWTPs) are increasingly required to meet stringent inorganic nitrogen discharge limits, necessitating reliable year-round ammonia oxidation and denitrification. Integrating biofilm-based technologies, such as Moving Bed Biofilm Reactors …
Oct 20, 2025Domestic wastewater is a complex mixture of organic and synthetic compounds. Its overall strength is typically assessed using indicators like BOD₅ (Biochemical Oxygen Demand), COD (Chemical Oxygen Demand), and TOC …
Oct 14, 2025We are often asked about the impact of various chemicals on wastewater treatment plants. Over the years, we have compounded a list of the primary industrial chemicals that inhibit the …
Oct 12, 2025As temperatures drop, wastewater treatment plants face a seasonal challenge that’s as subtle as it is critical: maintaining the delicate balance between nitrifying bacteria and filamentous organisms. Winter operations demand …
Oct 6, 2025Quaternary Ammonium Compounds (QACs) are commonly found in disinfectants, detergents, and personal care products. Their extensive use has led to increased concentrations in wastewater. To better understand how this impacts …
Sep 26, 2025In wastewater treatment, invisible forces shape the performance of entire systems. One of the most powerful—and often overlooked—players in this microbial drama is the polyvalent cation. These positively charged ions, …
Sep 16, 2025Wastewater treatment is a complex process that relies on a delicate balance of physical, chemical, and biological factors. At the heart of most conventional wastewater treatment plants are microorganisms that …
Sep 3, 2025When it comes to nitrogen monitoring in wastewater, ammonia often steals the spotlight. But if you’re only tracking ammonia, you’re missing a critical piece of the puzzle: Total Kjeldahl Nitrogen …
