Spiralklean Exercise:

Task:

A wastewater treatment plant currently uses a traditional screenings washing system. They are considering switching to a Spiralklean system.

• Calculate the potential cost savings: Assume the plant currently disposes of 100 tons of screenings per month at a cost of $50 per ton. The Spiralklean system reduces screenings volume by 30%. Estimate the monthly disposal cost savings with the Spiralklean system.

• Evaluate the environmental impact: Describe two specific ways that the Spiralklean system could reduce the plant's environmental impact.

Instructions: Show your calculations and provide a brief explanation for your environmental impact evaluation.

Techniques

Spiralklean: A Revolution in Screenings Washing for Water Treatment

Chapter 1: Techniques

The Spiralklean system employs a novel technique in screenings washing, differentiating itself from traditional methods. Instead of relying on inefficient methods like simple rinsing or pressure washing, Spiralklean utilizes a continuous spiral washing process. This technique involves:

1. Spiral Drum Rotation: Screenings are introduced into a rotating spiral drum. The continuous rotation ensures even exposure to the washing water. The spiral design promotes a gentle, yet effective, scrubbing action against the drum's screen, dislodging organic material.

2. Targeted Water Spray: A precisely controlled water spray system is integrated into the drum. The spray is strategically directed to maximize the removal of organic matter while minimizing water usage. This targeted approach avoids the excessive water consumption of traditional methods.

3. Centrifugal Force: The rotation of the spiral drum utilizes centrifugal force to aid in separating the wash water from the screenings. This enhances the efficiency of solids separation and produces drier, cleaner screenings.

4. Counter-Current Flow (Optional): Depending on the specific model and application, a counter-current flow system can be integrated. This allows cleaner water to contact the already partially cleaned screenings, enhancing the washing efficiency and minimizing water consumption.

This combination of techniques results in a superior washing process, leading to significant reductions in both the volume and organic content of the screenings. This contrasts sharply with traditional methods, which often leave screenings wet, heavy, and laden with organic matter.

Chapter 2: Models

Parkson Corporation offers a range of Spiralklean models to suit various wastewater treatment plant capacities and operational requirements. While specific model details are proprietary, the range typically includes variations based on:

• Capacity: Models are available to handle different throughput volumes of screenings, catering to small, medium, and large-scale treatment plants. Larger models incorporate multiple spiral drums to increase processing capacity.

• Automation Level: Models range from basic systems with manual controls to fully automated systems with PLC (Programmable Logic Controller) integration, allowing for remote monitoring and control. Automated systems often incorporate features like automatic level control and optimized water usage management.

• Screen Mesh Size: The size of the screen mesh within the spiral drum can be customized to match the specific needs of the plant, allowing for the removal of screenings of varying sizes and compositions.

• Additional Features: Some models might include integrated dewatering systems or features designed to optimize biogas production from the processed screenings.

The modular design of Spiralklean models allows for flexible configuration and adaptation to existing infrastructure, simplifying integration into existing wastewater treatment plants.

Chapter 3: Software

While the core Spiralklean system doesn't rely on sophisticated software for its basic operation, advanced models often incorporate software for:

• SCADA (Supervisory Control and Data Acquisition) systems: These provide centralized monitoring and control of the entire Spiralklean system, allowing operators to remotely monitor key parameters such as water usage, drum rotation speed, and screenings output. Data can be logged and analyzed for performance optimization.

• Predictive Maintenance Software: Data collected from the SCADA system can be used for predictive maintenance, identifying potential issues before they lead to downtime. This minimizes maintenance costs and ensures continuous operation.

• Reporting and Analytics: Software can generate reports on various key performance indicators (KPIs), such as the volume of screenings processed, water consumption, and the reduction in organic matter. This data is invaluable for evaluating the effectiveness of the system and making informed operational decisions.

Chapter 4: Best Practices

To maximize the effectiveness and longevity of a Spiralklean system, operators should adhere to these best practices:

• Regular Maintenance: Adhering to a strict maintenance schedule, including regular inspections and cleaning of the spiral drum and water spray system, is crucial. This ensures optimal performance and extends the lifespan of the equipment.

• Proper Screenings Feed: Ensuring a consistent and controlled feed of screenings into the system is essential to avoid overloading the system and maintaining uniform washing.

• Water Management: Optimizing water usage is key to minimizing costs and environmental impact. Properly adjusting the water spray system and utilizing counter-current flow (where applicable) are important for efficient water management.

• Operator Training: Proper training of plant operators is essential to ensure safe and effective operation of the Spiralklean system. This includes understanding the system's controls, maintenance procedures, and troubleshooting techniques.

• Data Analysis: Regularly analyzing the data collected by the system's monitoring software can help identify areas for improvement and optimize the system's performance.

Chapter 5: Case Studies

[This section would require specific data from Parkson Corporation on actual implementations of the Spiralklean system. It would ideally include information like:]

• Case Study 1: A description of a wastewater treatment plant that implemented the Spiralklean system. This should include information on the plant's size, the challenges faced before implementing the system, the results achieved (e.g., reduction in disposal costs, improved biogas production, reduced odor), and overall satisfaction.

• Case Study 2 (and beyond): Similar case studies showcasing the Spiralklean system's effectiveness in different contexts, such as different plant sizes, geographic locations, or types of wastewater. Quantitative data, like percentage reductions in disposal costs or improvements in biogas yield, would strengthen these case studies. The inclusion of before-and-after comparisons would also be beneficial.

The case studies would demonstrate the real-world benefits of the Spiralklean system and provide compelling evidence of its effectiveness as a revolutionary solution for screenings washing in water treatment.
