Wastewater Monitoring Series, Part 1: Identifying the Gaps in Conventional Biomass Test Methods in Wastewater
Biological wastewater treatment systems require living biomass to remove biodegradable contaminants from wastewater. Effective treatment is directly dependent on the concentration of healthy biomass. It stands to reason that having an easy method to directly measure the quantity and quality of living biomass would be tremendously beneficial to the operation of biological wastewater treatment ...

Using respirometry for energy optimization in a nitrifying biological wastewater treatment system
ABSTRACT Many wastewater treatment plants use more than 50% of their total energy budget in the aeration basin and, when nutrient removal is included in the activated sludge process, it is very common that the majority of oxygen uptake goes to the nitrification process. For that reason, in most wastewater treatment plants, energy optimization is focused on nitrification management. This ...

The potential role of ‘
Candidatus Microthrix parvicella’ in phosphorus removal during sludge bulking in two full-scale enhanced biological phosphorus removal plantsWe investigated the bacterial community compositions and phosphorus removal performance under sludge bulking and non-bulking conditions in two biological wastewater treatment systems (conventional A2/O (anaerobic/anoxic/aerobic) and inverted A2/O (anoxic/anaerobic/aerobic) processes) receiving the same raw wastewater. Sludge bulking resulted in significant shift in bacterial compositions from ...

Occurrence and enrichment of ‘bacterial sherpas’: climb to sustainability in wastewater treatment
The paper presents research on hemoglobin (Hb)-expressing bacteria in biological wastewater treatment systems. The outcome(s) will greatly reduce the aeration needs of wastewater treatment plants (WWTPs) and provide insight into emerging biological nitrogen removal processes using low dissolved oxygen (DO) conditions. In anthropogenic terms, the bacteria that express Hb could be considered as ...

The impact of slowly biodegradable organic compounds on the oxygen uptake rate in activated sludge systems
The hydrolysis process of slowly biodegradable substrate (XS) has an impact on the efficiencies of nutrient removal in activated sludge systems. Measurement of oxygen utilization rates (OURs) and corresponding chemical oxygen demand (COD) is accepted as a very useful tool to reflect the consumption of biodegradable substrates. The influence of the SS fraction in biological wastewater treatment ...

Is the whole the sumof its parts? Agent-basedmodelling of wastewater treatment systems
Agent-based models (ABMs) simulate individual units within a system, such as the bacteria in a biological wastewater treatment system. This paper outlines past, current and potential future applications of ABMs to wastewater treatment. ABMs track heterogeneities within microbial populations, and this has been demonstrated to yield different predictions of bulk behaviors than the conventional, ...

Modeling hydrolysis of slowly biodegradable organic compounds in biological nutrient removal activated sludge systems
Hydrolysis is an important process in biological wastewater treatment and is known to be the rate-limiting step in organic carbon removal from municipal or industrial wastewater. The influence of the readily biodegradable chemical oxygen demand fraction in biological wastewater treatment systems has been extensively investigated, but little is known about the effects of slowly biodegradable ...

How to Choose the Correct Biological Wastewater Treatment Process for Your Application
There is different discharge restrictions for wastewater produced by different sectors and industries. Treatment systems need to be designed around each individual application in order to specifically target and treat the pollutants produced by them. This is why it is important to choose the correct biological wastewater treatment process for secondary stage wastewater treatment. When choosing ...

Robust Systems for Optimal Treatment - Big-Park – Case Study
Overview Big Park Domestic Wastewater Improvement District in Arizona had constructed a new 500,000 gallons per day biological wastewater treatment system in 1997. As time passed, the aging plant was unable to keep up with increasing demands. Challenges In 2012, the District started working with Sunrise Engineering to find a solution that would work in their existing plant. Sunrise Engineering ...

How to prepare your WWTP for cold weather
Being proactive during cold weather can noticeably reduce wastewater treatment plant upsets While most people enjoy the cooler temperatures that come with fall, they can cause a well-running wastewater treatment plant to have issues almost overnight. Bacteria do not reduce BOD or reproduce as effectively during the colder months of the year. They generally favor temperatures between 68 and ...

Alpine resort leads the way in wastewater treatment
One of the world’s most popular ski resorts, Courchevel in the French Alps, has introduced an innovative wastewater treatment system to manage the sharp increase in capacity needed during the winter months. During the winter months, the population of Courchevel triples and the traditional aerated wastewater treatment system at nearby Bozel was finding it difficult to meet demand. The local ...

Is modeling of biological wastewater treatment a mature technology?
Based on three case studies it is demonstrated that the application of mathematical models in biological wastewater treatment has not yet reached its full potential. Model structure uncertainty and correlation of uncertain parameter values make up the first case. The combination of biokinetic and hydraulic models relates to the second case. The evolution of a full scale plant over its life ...

Advantages of MBRs Over Conventional Biological Treatment Method
1. What is MBR (Membrane Bioreactor)? The MBR (Membrane Bioreactor) which was first used in the late 1960s made a revolution in the wastewater industry in the early 1990s by combining membrane filtration with a biological treatment solution to treat wastewater. It's been commonly used since then and can be seen widely practiced in the design of both new and old wastewater treatment facilities. ...

Fighting the water crisis with wastewater recycling
Whether it’s sewage, domestic greywater or industrial run-off, wastewater recycling can play a critical role in averting the water crisis. Water scarcity is a significant climate change risk, but several other factors converge to make it a bigger problem than people realise. Add localised population growth, increased urbanisation, and water mismanagement, and you have a ...

4 Typical Misconceptions of MBBR for Wastewater Treatment
When looking for information about a product or service you’re interested in, it can occasionally be difficult to find the answers to your specific questions. Sometimes you can’t really find anything and you end up making inferences based on what you did find. Sometimes, those inferences can be partially or completely wrong. Since you’re here, you’ve likely been looking into moving bed biofilm ...
