Posi-Clean: A Revolution in Environmental & Water Treatment with Wedgewire Straining Elements

Chapter 1: Techniques

Wedgewire Straining: A Powerful Filtration Technique

Wedgewire straining, a key component of Posi-Clean technology, is a filtration technique that utilizes precision-engineered wedge-shaped wire elements to separate solids from liquids. This technique excels in various applications due to its unique advantages:

• Self-Cleaning Action: The wedge-shaped wire design creates a self-cleaning surface that prevents clogging, ensuring consistent flow and minimizing maintenance.
• Precise Particle Separation: The spacing between the wires can be customized to target specific particle sizes, offering precise and effective filtration.
• High Flow Rates: The open design of wedgewire elements maximizes surface area for filtration, allowing for high flow rates and reduced pressure drop.
• Durable Construction: Wedgewire elements are typically made from stainless steel or other corrosion-resistant materials, ensuring long-lasting performance in harsh environments.

Applications of Wedgewire Straining

Wedgewire straining finds wide applications in various sectors, including:

• Industrial Wastewater Treatment: Removing solids from wastewater to meet discharge standards.
• Municipal Water Filtration: Pre-filtering raw water to remove debris before further treatment.
• Water Well Screens: Protecting wells from contamination by filtering out sediment and debris.
• Food & Beverage Processing: Separating solids from liquid products like juice and sauces.
• Mining & Mineral Processing: Removing unwanted particles from slurries and concentrates.
