The world of environmental and water treatment is constantly evolving, seeking solutions that are both efficient and sustainable. One technology that has proven its worth is the Rotating Biological Contactor (RBC) aeration system. These systems, characterized by their rotating discs that provide a large surface area for biological growth, effectively treat wastewater. However, recent advancements have led to the introduction of SideCar technology, a powerful add-on that significantly enhances RBC performance.
Developed by Jones MacCrea, Inc., SideCar is an innovative attachment that utilizes bioaugmentation – introducing specific beneficial bacteria to enhance the natural treatment process. These bacteria, specifically selected for their effectiveness in treating target pollutants, are housed within a bioreactor integrated onto the SideCar.
The SideCar operates in tandem with the existing RBC system. As wastewater flows through the RBC, it encounters the SideCar, where the bioreactor's specialized bacteria actively break down target pollutants. The system is designed to:
SideCar represents a significant advancement in environmental and water treatment technology. By harnessing the power of bioaugmentation, this technology enhances the efficiency and effectiveness of RBC systems, enabling treatment facilities to address a wider range of pollutants and achieve greater sustainability. As environmental concerns continue to grow, solutions like SideCar will play a vital role in safeguarding our water resources and creating a cleaner future.

This document expands on the SideCar technology, breaking down its applications into distinct chapters.
Chapter 1: Techniques
SideCar employs the technique of bioaugmentation, a process where specific, highly effective microorganisms are introduced into an existing ecosystem to enhance its ability to degrade targeted pollutants. Unlike traditional methods that rely solely on the naturally occurring microbial communities, SideCar proactively introduces pre-selected bacterial strains optimized for the specific pollutants present in the wastewater. This targeted approach offers several advantages:
Increased efficiency: The pre-selected bacteria are already adapted to metabolize the target pollutants, leading to faster and more complete degradation compared to relying on the slow adaptation of naturally occurring bacteria.
Enhanced stability: The introduction of robust, specialized bacteria makes the treatment process less susceptible to fluctuations in wastewater composition or temperature, resulting in more consistent performance.
Reduced treatment time: The higher metabolic activity of the augmented bacteria results in faster processing times, potentially reducing the size of required infrastructure and overall treatment duration.
The bioreactor within the SideCar is specifically designed to maintain optimal conditions for the introduced bacteria—temperature, pH, and nutrient availability—maximizing their activity and longevity. The design incorporates mechanisms to prevent washout of the bacterial culture and ensure efficient contact between the wastewater and the bacteria. Regular monitoring of the bacterial population and performance within the bioreactor is crucial for maintaining optimal treatment efficiency.
Chapter 2: Models
The effectiveness of SideCar is dependent on several factors, including the type and concentration of target pollutants, the characteristics of the influent wastewater, and the operating conditions of the RBC system. Modeling plays a crucial role in predicting the performance of SideCar and optimizing its design and operation. Various models can be employed, ranging from simple empirical models to complex mechanistic models:
Empirical Models: These models correlate readily available parameters (e.g., influent pollutant concentration, effluent concentration) to predict the performance of SideCar. They are relatively simple to implement but might lack predictive power for significantly different operating conditions.
Mechanistic Models: These models incorporate detailed descriptions of the biological and chemical processes within the bioreactor and the RBC system. They require more data and computational resources but offer a deeper understanding of the system's behavior and greater predictive accuracy. These models can incorporate factors such as bacterial growth kinetics, substrate utilization, and mass transfer limitations.
Model selection depends on the specific application and the available data. Calibration and validation of the selected model using field data are essential for ensuring reliable predictions.
Chapter 3: Software
Several software packages can be utilized for modeling and data analysis related to SideCar's performance. These include:
Specialized wastewater treatment simulation software: Software such as BioWin or GPS-X can simulate the entire wastewater treatment process, including the RBC system and the SideCar bioreactor, allowing for comprehensive analysis of the system's behavior under different scenarios.
Statistical software packages: Software such as R or SPSS can be used for data analysis, statistical modeling, and parameter estimation for empirical models.
Computational fluid dynamics (CFD) software: Software like ANSYS Fluent can simulate the flow patterns and mixing within the SideCar bioreactor, providing insights into the efficiency of the bioaugmentation process.
The choice of software depends on the complexity of the model, the available data, and the specific requirements of the analysis. Proper training and expertise are crucial for effective use of these software packages.
Chapter 4: Best Practices
To ensure optimal performance and longevity of the SideCar system, several best practices should be followed:
Careful selection of bacterial strains: The choice of bacteria should be tailored to the specific pollutants present in the wastewater. The strains should be robust, have high metabolic activity, and be tolerant to the operating conditions of the bioreactor.
Regular monitoring and maintenance: Regular monitoring of the bacterial population, pH, temperature, and nutrient levels within the bioreactor is crucial for early detection of any issues and timely intervention. Regular cleaning and maintenance of the SideCar unit will also prolong its lifespan.
Proper operation and control: The SideCar system needs to be integrated effectively with the existing RBC system. Appropriate control strategies should be implemented to maintain optimal operating conditions.
Appropriate safety measures: Safety precautions should be taken during installation, operation, and maintenance to prevent accidental exposure to the bacterial cultures.
