Stir it up: Five tips for more effective industrial aeration
We all know that aeration is a simple but versatile secondary treatment, with uses ranging from removing gases and dangerous compounds from wastewater, to encouraging the action of microbes as they break down solids. If you’re using aeration in an industrial setting, you may be producing streams with concentrations of biological oxygen demand (BOD), chemical oxygen demand (COD), and ...

Design configurations for commercial application of biomass carriers in small wastewater treatment plants
Introduction Moving bed type reactors are bio-film processes utilizing small, plastic biomass carriers that mix in the water. The use of biomass carriers is becoming common world-wide, for many applications, some of which are: compact low operation units, industrial wastewater roughing filters, retrofit and upgrade of municipal wastewater treatment plants. The AGARTM Process (Attached Growth ...

The role of colloidal and particulate organic compounds in denitrification and EBPR occurring in a full-scale activated sludge system
The efficiencies of denitrification and enhanced biological phosphorus removal (EBPR) in biological nutrient removal (BNR) activated sludge systems are strongly dependent on the availability of appropriate carbon sources. Due to high costs of commercial compounds (such as methanol, ethanol, acetic acid etc.) and acclimation periods (usually) required, the effective use of internal carbon sources ...

Assessment of the endogenous respiration rate and the observed biomass yield for methanol-fed denitrifying bacteria under anoxic and aerobic conditions
In this study, the endogenous respiration rate and the observed biomass yield of denitrifying methylotrophic biomass were estimated through measuring changes in denitrification rates (DNR) as a result of maintaining the biomass under methanol deprived conditions. For this purpose, activated sludge biomass from a full-scale wastewater treatment plant was kept in 10-L batch reactors for 8 days ...

The Hidden Dangers of Industrial Mop Water, Examining little-known threats to the environment & wastewater treatment processes
When we think of mop water, most likely we think of our kitchen floor. In industrial plants, however, mop water could contain a toxic blend of chemicals that are mopped off the floor, and sometimes end up in our rivers, streams and municipal wastewater systems. While we consider the health of our environment, we don’t necessarily realize the hidden dangers of mop water. This article ...
