Techniques

Chapter 1: Techniques

Barminutor: A Combined Approach to Screening and Comminution

The heart of a barminutor lies in its innovative approach to wastewater treatment. It combines the functionality of a bar screen and a comminutor into a single, integrated unit. This design addresses the limitations of traditional, separate systems, resulting in a more efficient and effective solution.

1.1 Bar Screen Function:

The bar screen, acting as the first line of defense, physically removes large debris such as branches, rags, and plastics from the wastewater stream. This prevents these objects from clogging pumps, damaging equipment, or interfering with downstream treatment processes.

1.2 Comminutor Function:

The comminutor component follows the bar screen, further processing the remaining smaller solids. It utilizes rotating blades or grinders to shred these solids into manageable pieces. This ensures that the solids can be effectively treated by subsequent stages of the wastewater treatment process.

1.3 Combined Operation:

The barminutor seamlessly combines these two functions. As the wastewater flows through the unit, it first encounters the bar screen, which removes large debris. Then, the smaller solids pass through the comminutor, where they are effectively reduced in size. This integrated process ensures that the wastewater is thoroughly screened and comminuted before entering the next stages of treatment.

1.4 Advantages of the Barminutor Technique:

• Efficiency: The barminutor eliminates the need for separate equipment, streamlining the treatment process and saving space.
• Reliability: The combined approach ensures a complete removal of large debris and effective reduction of smaller solids, preventing clogging and downtime.
• Cost-effectiveness: By eliminating the need for separate units and reducing maintenance requirements, the barminutor offers a cost-effective solution.

Chapter 2: Models

Diverse Barminutor Designs: Catering to Various Needs

Barminutor manufacturers, like Yeomans Chicago Corp., offer a variety of models to accommodate the specific requirements of different wastewater treatment facilities. Each model features unique design elements that optimize performance for specific flow rates, debris types, and treatment goals.

2.1 Key Design Considerations:

• Bar Screen Configuration: Barminutors can employ various bar screen designs, including vertical, inclined, or horizontal bars. The choice depends on the size and type of debris expected and the required flow capacity.
• Comminutor Mechanism: The comminutor can utilize different mechanisms, such as rotating blades, grinders, or shredders. The selected mechanism determines the final particle size of the comminuted solids.
• Material Selection: Barminutor components are typically made of durable materials, such as stainless steel or cast iron, to withstand the harsh environment of wastewater treatment.
• Control Systems: Some models offer advanced control systems that automate cleaning cycles, monitor performance, and provide real-time data on the treatment process.

2.2 Popular Barminutor Models:

• Yeomans Model 5100: This model features a robust bar screen and a powerful comminutor capable of handling high flow rates and large debris.

• Yeomans Model 5120: This heavy-duty model is ideal for challenging applications, such as industrial wastewater treatment or municipal facilities with large debris loads.

2.3 Choosing the Right Barminutor Model:

Selecting the appropriate model requires careful consideration of the following factors:

• Flow Rate: Determine the average and peak flow rates expected from the wastewater source.
• Debris Type: Identify the types of debris that are likely to be present in the wastewater.
• Treatment Goals: Define the desired level of solids removal and the acceptable size of the comminuted solids.
• Budget and Space Constraints: Consider the available budget and the space limitations of the treatment facility.

By carefully evaluating these factors, wastewater treatment professionals can choose the optimal barminutor model for their specific application.
