Chapter 1: Techniques

Granular Media Filtration: The Foundation of Auto-Shell

The Auto-Shell system relies heavily on the proven technology of granular media filtration. This technique involves passing water through a bed of granular materials like sand, anthracite, or activated carbon. The different media types have varying pore sizes and surface properties, allowing for targeted removal of specific contaminants.

• Sand Filtration: This is the most common type of granular media filtration, effectively removing suspended solids and turbidity.
• Anthracite Filtration: Anthracite is a denser and harder form of coal that offers a larger surface area for filtration, allowing for the removal of finer particles than sand.
• Activated Carbon Filtration: Activated carbon excels in removing organic compounds, chlorine, and taste and odor-causing substances.

The Auto-Shell system facilitates efficient granular media filtration by:

• Pre-engineered Design: The system provides a pre-designed framework, eliminating the need for complex on-site engineering and reducing setup time.
• Backwashing System: The built-in backwashing system ensures consistent media cleanliness and prevents clogging, maximizing filter performance.
• Automated Control: Advanced controls regulate backwashing and monitor filter performance, minimizing manual intervention and optimizing efficiency.

Other Filtration Techniques used with Auto-Shell

While granular media filtration is the primary technique employed in Auto-Shell, other filtration methods can be combined to enhance its effectiveness for specific applications. These techniques include:

• Membrane Filtration: This technique utilizes semi-permeable membranes to physically separate contaminants from water, allowing for the removal of even smaller particles than granular media.
• Coagulation and Flocculation: These processes involve adding chemicals to water to bind smaller particles together, forming larger flocs that are easily removed by granular media filtration.
• Disinfection: This step involves using ultraviolet (UV) radiation or chlorine to kill harmful bacteria and viruses in the treated water.

The Auto-Shell system's modularity allows for easy integration of these additional techniques to address specific water quality challenges.
