Screens and Strainers

Screens and Strainers are essential components in water and wastewater treatment systems, designed to remove solid particles, debris, and other materials from water streams before they enter further stages of treatment. These systems act as the first line of defense in protecting pumps, valves, and other sensitive equipment from clogging and damage caused by larger solids. Screens and strainers improve the efficiency of treatment processes by preventing blockages and reducing the overall solid load on downstream equipment.

Screens are generally used in wastewater treatment plants, stormwater systems, and industrial water processes to filter out large solids, while strainers are often used in systems requiring finer filtration, such as in cooling water systems and potable water treatment. Providers in this subcategory offer a range of solutions, from coarse bar screens to fine mesh strainers, ensuring reliable and efficient solid removal across a variety of applications.

1. Bar Screens
• Consist of vertical or inclined bars used to capture large debris such as branches and plastics, commonly used in the initial stages of water treatment.

2. Rotary Drum Screens
• Cylindrical devices that rotate to capture and remove suspended solids, allowing cleaner water to pass through while trapping solids on the surface.

3. Fine Screens
• Capture smaller particles that pass through bar or coarse screens, made of fine mesh or perforated plates to protect downstream processes.

4. Coarse Screens
• Remove larger particles and debris before finer filtration stages, commonly used in the preliminary stages of water and wastewater treatment.

5. Static Screens
• Fixed devices that allow water to pass through while retaining solids, used in low-flow systems without moving parts.

6. Self-Cleaning Strainers
• Automatically remove trapped debris from the filter element without interrupting the water flow, ideal for continuous operation.

7. Wedge Wire Screens
• Use V-shaped wire profiles to retain solids while allowing water to flow through, highly durable with precise filtration.

8. Manual Strainers
• Simple filtration devices that require periodic manual cleaning to remove trapped solids, used in low-maintenance applications.

9. Screening and Straining System Maintenance
• Regular maintenance services to ensure optimal performance, preventing clogging and extending the life of the systems.
