SS304 Wedge Wire MBBR Media Retention Screen with 1-6 mm Slot Size and 50-5,000

Product Specification

MBBR Media Retention Screen System for Latin American Wastewater Treatment Plants

Our MBBR Media Retention Screen System (Model BM-MRS500) is a precision-engineered SS304 wedge wire drum filter designed specifically for MBBR biofilm carrier separation in wastewater treatment plants across Latin America. These retention screens prevent costly carrier loss from reactor basins while maintaining design hydraulic throughput, protecting downstream equipment and ensuring environmental compliance for municipal and industrial MBBR installations in Brazil, Mexico, Colombia, and Chile.

Critical MBBR Component for Reliable Latin American Operations

• Carrier Retention Without Compromise: The MBBR process depends on reliable biofilm carrier retention. Our BM-MRS500 wedge wire screens feature continuous-slot V-profile wires that provide precise 1–6mm slot openings, preventing even the smallest K1 carriers (12×9mm) from escaping while maintaining low headloss. Custom slot sizing available for K5 carriers and specialty media used in Latin American installations.
• SS304 Construction for Harsh Environments: Fabricated from stainless steel 304 with SS316 upgrade option for coastal and high-salinity applications. Resistant to hydrogen sulfide corrosion common in tropical wastewater, unlike carbon steel screens that require frequent replacement in Latin American treatment plants. Welded construction eliminates bolt-hole corrosion points.
• Engineered for High Hydraulic Loading: Cylindrical drum geometry maximizes screen surface area within existing reactor wall openings. Each BM-MRS500 handles 50–5,000 m³/d per screen with headloss under 50mm at design flow. Multiple screens can operate in parallel for high-capacity MBBR reactors, with flow distribution baffles ensuring even loading.
• Anti-Clogging Air Scour System: Integrated air scour manifold directs coarse bubbles across the screen face during normal operation, preventing biofilm accumulation and fibrous material blinding. Optional mechanical brush cleaning for plants treating high-fiber industrial wastewater (textile, pulp & paper) common in Colombian and Brazilian industrial sectors.
• Regional Support Network: Screen sizing calculations, hydraulic analysis, and installation supervision available in Spanish and Portuguese. Spare screen assemblies stocked at regional warehouses for emergency replacement without extended plant downtime. Custom fabrication for non-standard reactor wall openings and retrofit applications.
