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: The Simon-Hartley Advantage
Simon-Hartley, Ltd., a leading manufacturer of wastewater treatment equipment, has built a strong reputation for its Simrake rotary bar screens. Here are some key features and benefits of these screens:
- Robust Construction: Simrake screens are built to withstand the rigors of wastewater treatment, featuring durable materials and robust designs.
- Customization: Available in various sizes and configurations to suit specific flow rates and debris removal requirements.
- Efficient Operation: Designed for smooth, reliable operation, minimizing maintenance and downtime.
- Advanced Features: Options for automatic cleaning systems, debris collection hoppers, and control systems for optimized performance.
- Environmentally Friendly: Simrake screens help reduce pollution by effectively removing debris, preventing blockages, and improving overall treatment efficiency.
Applications of Simrake Rotary Bar Screens
Simrake rotary bar screens find widespread applications in various wastewater treatment settings, including:
- Municipal Wastewater Treatment Plants: Removing debris from raw sewage before it enters the treatment process.
- Industrial Wastewater Treatment: Protecting industrial equipment from clogging and damage caused by debris.
- Stormwater Management Systems: Filtering debris from stormwater runoff before it enters sewer systems or storm drains.
- Water Reuse Systems: Ensuring that water used for irrigation or other purposes is free from large debris.
The Importance of Debris Removal
Effective debris removal is crucial for efficient and reliable wastewater treatment. Simrake rotary bar screens offer a robust and reliable solution, ensuring that:
- Downstream equipment is protected: Debris can clog pumps, filters, and other treatment components, leading to breakdowns and costly repairs.
- Treatment processes are optimized: Removal of debris allows for smoother flow and better performance of the overall wastewater treatment system.
- Environmental impact is minimized: Preventing debris from entering water bodies reduces the potential for pollution and harmful effects on aquatic life.
In conclusion, Simrake rotary bar screens by Simon-Hartley, Ltd., are a vital component of modern wastewater treatment systems. Their robust design, customization options, and advanced features make them an effective and reliable solution for efficient debris removal, safeguarding equipment, and optimizing the entire treatment process.

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.
