Shriver Filter Press Exercise

Task: A wastewater treatment plant needs to remove suspended solids from a large volume of wastewater. They are considering using a Baker Process Shriver filter press.

Problem: The plant manager is concerned about the cost of operating the filter press. They are considering using a cheaper, less efficient alternative.

Instructions: Write a short paragraph explaining why the plant manager should choose the Shriver filter press despite the higher initial cost. Focus on the long-term benefits of the Shriver press and the potential drawbacks of using a less efficient alternative.

Exercice Correction

While the initial cost of a Shriver filter press might seem high, its long-term benefits far outweigh the cost savings of a less efficient alternative. The Shriver press ensures a higher quality filtrate, reducing the need for further treatment and minimizing the environmental impact of wastewater discharge. Its high throughput allows for efficient processing of large volumes, contributing to cost savings in the long run. Furthermore, the Shriver press's durability and ease of maintenance minimize downtime, ensuring continuous and reliable operation. Choosing a cheaper alternative may result in lower initial cost but could lead to higher operational costs, increased downtime, and a less effective treatment process. Ultimately, the long-term benefits of the Shriver press in terms of efficiency, reliability, and environmental impact make it a more valuable investment for the wastewater treatment plant.

Techniques

Chapter 1: Techniques

Solid-Liquid Separation with Shriver Filter Presses

This chapter explores the fundamental techniques employed by Shriver filter presses in achieving efficient solid-liquid separation.

1.1. Plate and Frame Design:

The Shriver filter press utilizes a series of plates and frames to create filter chambers. The plates have a filter medium (typically filter cloth) embedded in them, while the frames are hollow for collecting the filtrate.

1.2. Filtration Process:

The process involves feeding slurry into the press, which is then pumped through the filter cloth under pressure. This pressure forces the liquid (filtrate) through the cloth, leaving the solids trapped on the surface.

1.3. Cake Formation:

As filtration progresses, the solids build up on the filter cloth, forming a "cake." The cake acts as an additional filter layer, further refining the filtrate.

1.4. Pressure Control:

The pressure applied during filtration is crucial. Higher pressure can increase filtration rate but also increase cake resistance. Baker Process Shriver filter presses offer precise pressure control for optimizing performance.

1.5. Cake Discharge:

Once the filtration cycle is complete, the cake is discharged from the press. This can be achieved through various methods, including manual scraping, automated cake blow-back, or the use of a cake discharge valve.

1.6. Filter Cloth Selection:

The choice of filter cloth is critical for effective separation. Factors like particle size, chemical compatibility, and flow rate influence the selection.

1.7. Applications:

The versatility of Shriver filter presses allows for a wide range of applications, including:

  • Sludge Dewatering: Removing water from sewage sludge to reduce its volume for disposal.
  • Wastewater Treatment: Separating solids from industrial wastewater for recycling or disposal.
  • Chemical Processing: Separating solids from liquid in various chemical manufacturing processes.

1.8. Advantages of Shriver Filter Presses:

  • High Solids Capture Efficiency: Shriver filter presses can remove a wide range of solids, including fine particles.
  • Variable Throughput: The press design allows for adjusting the filter area to accommodate different processing volumes.
  • Versatile Operation: Can handle a variety of slurries with varying particle sizes and concentrations.

1.9. Limitations:

  • Cake Handling: Cake discharge can be labor-intensive, depending on the chosen method.
  • Operational Costs: Press operation requires energy for pumping and cake disposal.

This chapter provides an overview of the techniques involved in solid-liquid separation using Shriver filter presses, laying the foundation for exploring further details in subsequent chapters.
