Chapter 1: Techniques

Yeomans Chicago Corporation and Advanced Water Treatment Techniques

The "Chicago" legacy in water treatment, embodied by Yeomans, isn't solely about the pumps themselves; it's about the application of advanced techniques made possible by their reliable equipment. Yeomans' involvement spans several crucial techniques:

• Sludge Dewatering: Yeomans' expertise extends beyond pumping. Their sludge dewatering systems utilize a combination of techniques including gravity thickening, belt filter presses, and centrifuge technology. The choice of technique depends on the sludge characteristics and desired dryness. Yeomans' pumps are integral to these systems, efficiently moving the sludge through various stages of dewatering. This directly addresses the significant environmental challenge of sludge disposal.

• Aeration and Oxygen Transfer: Efficient aeration is crucial for biological wastewater treatment. Yeomans' aerators employ various techniques to maximize oxygen transfer, including diffused aeration (using fine bubble diffusers) and surface aeration. The choice of aeration technique influences energy efficiency and treatment effectiveness. Yeomans' robust pumps ensure consistent air flow for optimal aeration.

• Solids Separation and Clarification: Yeomans' clarifiers and thickening systems utilize gravity settling and other physical separation techniques to remove solids from wastewater. These systems often incorporate specialized baffling and sludge removal mechanisms to optimize the separation process. Again, Yeomans' pumps play a critical role in efficiently transporting the separated sludge and clarified water.

• Pumping Technologies: The core of Yeomans' contribution lies in their advanced pumping technologies. They employ various impeller designs and pump types (submersible, non-submersible, centrifugal, rotary) optimized for different applications and fluid characteristics. These choices directly impact energy efficiency, handling capacity, and the ability to manage challenging fluids with high solids content or viscosity. The selection of the appropriate pumping technique is critical to the success of the overall water treatment process.

Chapter 2: Models

Yeomans' Range of Water Treatment Models

Yeomans offers a diverse range of models tailored to various water treatment applications and scales. While specific model numbers and configurations are proprietary, the underlying model types can be categorized as follows:

• Submersible Pump Models: These models vary in horsepower, flow rate, and head capacity to suit different applications, from small lift stations to large wastewater treatment plants. Materials of construction also vary based on the fluid handled (e.g., cast iron, stainless steel). Specific models are designed for sewage, stormwater, or industrial wastewater.

• Non-Submersible Pump Models: This category includes centrifugal and rotary pumps, each with diverse model variations based on flow rate, pressure, and fluid viscosity. Centrifugal pumps are suitable for handling relatively clear water, while rotary pumps are designed for viscous fluids and slurries. Materials and sealing mechanisms also differ depending on the application.

• Sludge Dewatering System Models: These models encompass different technologies, such as belt filter presses, centrifuges, and other mechanical dewatering systems. Each system has multiple model variations based on capacity, sludge type, and desired dryness. Integration with Yeomans' pumps is a key feature of these models.

• Aeration System Models: Yeomans' aerators are available in various configurations, including surface aerators and diffused aeration systems. Models differ in oxygen transfer capacity, power consumption, and suitability for different tank sizes and wastewater characteristics.

• Clarifier and Thickening System Models: Models within this category vary based on tank design, settling mechanisms, and sludge removal methods. They are tailored to handle different flow rates and sludge concentrations. Integration with Yeomans' pumps is critical for efficient sludge removal.

Chapter 3: Software

Yeomans and Supporting Software

While Yeomans doesn't directly produce dedicated water treatment modeling software, their commitment to engineering excellence is supported by the use of various software packages in design and operation:

• Computer-Aided Design (CAD) Software: Yeomans utilizes CAD software for designing and optimizing pump systems and wastewater treatment plants. This allows for precise modeling of piping layouts, tank configurations, and overall system performance.

• Computational Fluid Dynamics (CFD) Software: For complex system designs, Yeomans may use CFD software to simulate fluid flow patterns and optimize pump performance. This ensures efficient fluid transport and minimizes energy losses.

• Pump Selection Software: Internally, Yeomans likely employs specialized software to assist in pump selection based on project requirements, ensuring that the correct pump models are specified for each application. This software would consider factors like flow rate, head, fluid properties, and operating conditions.

• Data Acquisition and Control Systems (SCADA): While not software produced by Yeomans, their equipment is often integrated with SCADA systems to monitor and control water treatment plants. This allows for real-time monitoring of pump performance, flow rates, and other key parameters.

• Third-party design and simulation tools: Yeomans engineers likely utilize a range of third-party software tools for specific tasks such as hydraulic modeling or process simulation depending on the project scope and complexity.
