Simrake: A Powerful Tool in Environmental & Water Treatment
The term "Simrake" often appears in the context of environmental and water treatment, particularly when discussing the removal of debris from wastewater. It's not a specific technology itself, but rather a trademark used by Simon-Hartley, Ltd. for their range of rotary bar screens. These screens are crucial components in the initial stages of wastewater treatment, playing a vital role in safeguarding downstream equipment and optimizing the entire process.
What are Rotary Bar Screens?
Rotary bar screens are mechanical devices designed to remove large debris from wastewater flows. They consist of a rotating drum equipped with a series of bars or rakes. The wastewater flows through the screen, and the bars capture debris larger than the set gap. The rotating drum then carries the collected debris out of the flow and into a separate collection area for disposal.

Simrake: Exercise
Scenario:
You are a wastewater treatment plant operator responsible for overseeing the operation of a Simrake rotary bar screen. The screen is experiencing frequent clogging and requires more frequent cleaning than usual.
Task:
Identify three possible reasons for the increased clogging of the Simrake rotary bar screen. For each reason, suggest a corresponding solution to address the problem.
Exercice Correction
Here are three possible reasons for increased clogging and their corresponding solutions:
- **Reason:** **Increased debris load:** The amount of debris entering the wastewater treatment plant has increased. **Solution:** Investigate the source of the increased debris. This could involve analyzing incoming wastewater flow for changes in composition, identifying potential sources of additional debris in the surrounding area, or checking for any malfunctioning pre-treatment processes. Implement appropriate measures to reduce the debris load, such as installing additional screens upstream or improving source control measures.
- **Reason:** **Malfunctioning cleaning mechanism:** The automatic cleaning system of the Simrake screen is not functioning properly, allowing debris to build up. **Solution:** Inspect the cleaning mechanism and ensure it is operating as designed. This may involve checking the motor, brushes, or any other components associated with the cleaning system. Perform necessary repairs or adjustments to ensure efficient debris removal.
- **Reason:** **Improper screen gap setting:** The gap between the bars of the screen is too small, allowing finer debris to pass through and clog the screen. **Solution:** Adjust the screen gap to a more suitable size, balancing the need to remove large debris while minimizing clogging. Consult the manufacturer's specifications for recommended gap settings based on the specific Simrake model and the characteristics of the wastewater flow.

Simrake: A Powerful Tool in Environmental & Water Treatment
This document expands on the provided text, dividing the information into chapters focusing on Techniques, Models, Software, Best Practices, and Case Studies related to Simrake rotary bar screens. Note that information on specific models and software may be proprietary to Simon-Hartley and not publicly available in detail.
Chapter 1: Techniques
This chapter focuses on the mechanical techniques employed by Simrake rotary bar screens in removing debris from wastewater.
The core technique involves the use of a rotating drum fitted with a series of parallel bars or rakes. Wastewater flows through the screen, and debris larger than the gap between the bars is trapped. The rotation of the drum continuously carries the collected debris out of the flow, typically into a hopper for disposal.
Several techniques enhance the effectiveness of this basic principle:
- Bar Spacing Optimization: The spacing between the bars is crucial. Too wide, and larger debris passes through; too narrow, and clogging occurs and increases the load on the motor. Optimal spacing is determined by the type and size of anticipated debris.
- Drum Rotation Speed Control: The speed of the drum's rotation is adjustable, allowing for optimization based on flow rate and debris load. Slower speeds can handle higher debris loads, while faster speeds are suitable for lower loads and cleaner wastewater.
- Cleaning Mechanisms: Simrake screens often incorporate automatic cleaning systems. These can include high-pressure water jets or scrapers to remove accumulated debris from the bars, maintaining screen efficiency.
- Debris Handling: Efficient collection and disposal of the captured debris are vital. Hoppers with various capacities and designs accommodate different debris volumes and characteristics.
The overall efficiency of the technique depends on the careful selection and coordination of these factors, tailored to the specific application.
Chapter 2: Models
Specific models of Simrake rotary bar screens are generally proprietary information held by Simon-Hartley. However, the range likely includes various models differentiated by:
- Capacity: Screens are available to handle diverse wastewater flow rates, from smaller industrial applications to large municipal plants.
- Size and Dimensions: The physical dimensions of the screen (diameter, length) vary to accommodate different installation spaces and flow requirements.
- Bar Spacing: Different bar spacings cater to specific debris sizes and types.
- Material: The construction materials (stainless steel, etc.) influence durability and corrosion resistance, reflecting the aggressiveness of the wastewater.
- Automation Level: Models range from basic manual cleaning to fully automated systems with remote monitoring and control.
- Additional Features: Features like integrated pumps, pre-screen options, and specialized debris handling systems differentiate models.
Detailed specifications for each model would be available from Simon-Hartley directly.
Chapter 3: Software
While specific software associated with Simrake operation may not be publicly detailed, it's likely that Simon-Hartley provides:
- Design Software: This could be used for simulating wastewater flow, debris removal efficiency, and selecting the optimal Simrake model for a particular application. This might involve computational fluid dynamics (CFD) modeling.
- Monitoring and Control Software: Automated systems likely use software for real-time monitoring of screen performance (e.g., rotation speed, debris level, pressure, power consumption). This allows for remote diagnostics and predictive maintenance.
- Data Logging and Reporting Software: Collected data would be logged and used for performance analysis, reporting to regulatory bodies, and optimization of the treatment process.
The specifics of this software are likely proprietary to Simon-Hartley.
Chapter 4: Best Practices
Effective operation and maintenance of Simrake rotary bar screens require adherence to several best practices:
- Regular Inspection: Regular visual inspection of the screen for wear, tear, and clogging is crucial for preventative maintenance.
- Scheduled Maintenance: A preventative maintenance schedule should be followed, including lubrication, cleaning, and component replacement as needed.
- Debris Handling: Ensure efficient and sanitary disposal of collected debris according to local regulations.
- Operator Training: Proper training for operators on the operation, maintenance, and troubleshooting of the Simrake system is essential.
- Environmental Compliance: Adherence to all relevant environmental regulations regarding wastewater treatment and debris disposal is paramount.
- Data Analysis: Regular analysis of operating data can identify potential problems and optimize screen performance.
