Wastewater treatment is a carefully orchestrated process where microbial communities play a critical role in transforming harmful compounds into less hazardous forms. Among these transformations, nitrification—a two-step aerobic process—stands as …
Mar 12, 2025Phosphorus is a critical nutrient that, in excess, can lead to eutrophication in water bodies, causing harmful algal blooms and deteriorating water quality. Biological phosphorus removal (BPR) is an effective …
Feb 26, 2025When it comes to wastewater treatment, filamentous bacteria often get a bad rap. However, these microorganisms play a crucial role in the treatment process, especially when present in moderate numbers. …
Feb 12, 2025In wastewater treatment plants, biomass solids is a byproduct of the treatment process. It consists of a mixture of organic and inorganic materials, microorganisms, and bound water. Over time, sludge …
Jan 23, 2025You have probably read about probiotics (bioaugmentation) and prebiotics being used in wastewater treatment, postbiotics are another less talked about potential tool available for optimizing your biomass performance. Postbiotics application …
Dec 10, 2024For aerobic wastewater treatment systems, maintaining Dissolved Oxygen levels is key to efficient treatment. Operating a combination of blowers or surface aerators represents a significant use of energy/utility costs. Picking …
Dec 6, 2024Simultaneous Nitrification-Denitrification (SNdN) is an advanced process used in wastewater treatment to remove nitrogen compounds. Here’s a detailed look at how it works: Process Overview: Nitrification: This involves the biological …
Nov 21, 2024Wastewater bacteria growing in long chains of cells with high surface area are termed filamentous organisms. When you mention filamentous bacteria to most operators, the discussion usually focuses on the …
Nov 5, 2024Phosphate Accumulating Organisms (PAO) and Glycogen Accumulating Organisms (GAO) are two types of bacteria that play crucial roles in the enhanced biological phosphorus removal (EBPR) process in wastewater treatment. PAOs …
Oct 31, 2024Bioremediation application summaries are usually done on soils with high levels of contaminants and with highly biodegradable compounds such as fuels or crude oils. Aster Bio has been working on …
Oct 23, 2024You may have seen information on using molecular tools or genetic testing in wastewater treatment systems. While 15 years ago, this was either unavailable, expensive, and not useful, things have …
Oct 15, 2024Nitrification is one of the most complex and crucial processes within the wastewater microbial community. This biochemical process involves the conversion of ammonia (NH₃) into nitrate (NO₃⁻) and is carried …
