MBBR Moving Bed Biofilm Reactor System Including Media Retention Screen 50-5000 m³/d Latin America Wastewater Treatment

MBBR Moving Bed Biofilm Reactor System for Latin American Wastewater Treatment Plants

Suspended Bio‑active Carrier (Fluidized‑bed Filler) is a new‑type bio‑active carrier. Formulated with scientific proportions, it incorporates various trace elements beneficial to rapid microbial adhesion and growth into polymer materials according to different water quality requirements. Manufactured via special modification and structural‑forming processes, it features large specific surface area, favorable hydrophilicity, excellent flowability, high biological activity, easy biofilm formation, superior treatment performance and long service life.

Complete MBBR Solution Engineered for Latin American Conditions

• Integrated MBBR Design for Fast Deployment: The BM-MBBR5000 eliminates the coordination risk of sourcing carriers, screens, aeration, and controls from multiple suppliers. Every MBBR component is pre-sized, pre-tested, and shipped as a coordinated package, reducing on-site engineering time by 40-60% compared to piecemeal procurement approaches common in Latin American wastewater infrastructure projects.
• High-Efficiency Biofilm Carriers: Each MBBR system includes the optimal quantity of virgin HDPE biofilm carriers with ≥800 m²/m³ protected surface area. Carriers are available in K1 and K5 geometries to match specific treatment objectives, whether nitrification, denitrification, or combined BOD/ammonia removal in Latin American municipal and industrial wastewater applications.
• Proven Media Retention Technology: Integrated SS304 wedge wire cylindrical drum screens with 1-6 mm slot openings ensure zero carrier loss from the MBBR reactor while maintaining low headloss at design flows. Air scour manifolds direct coarse bubbles across screen faces to prevent biofilm accumulation and fibrous material blinding, eliminating manual screen cleaning requirements in remote Latin American installations.
• Optimized Aeration and Mixing: The MBBR aeration system combines coarse bubble diffusers for carrier mixing with fine bubble diffusers for oxygen transfer, achieving oxygen transfer efficiency (OTE) of 4.5-6.5% per meter of submergence. Positive displacement rotary blowers with VFD control match air delivery to real-time process demand, reducing energy consumption by up to 35% during low-load periods common in Latin American seasonal industrial operations.
• PLC Automation with Remote Monitoring: Every MBBR system includes a PLC controller with HMI touch screen for local operation and optional 4G/ Ethernet connectivity for remote monitoring and alarm notification. Pre-programmed control sequences manage blower cycling, air scour timing, and carrier fluidization, enabling operation by local staff without specialized wastewater treatment expertise across Latin America.

Product Technology Core

Design the geometric configuration according to fluid dynamics, strengthen the surface adhesion ability.

 The outer membrane of packing is renewed fast and active, the inner membrane is fully protected, the microorganisms are in good growth condition, changing the way of traditional packing's outer growth, so that the microorganisms' degradation efficiency is higher.

 The special structure makes the air bubbles and pollutants in the water can freely pass through the inside of the packing, which increases the contact chance between the biofilm and the oxygen pollutants, greatly improves the mass-transfer efficiency of the system, and improves the degradation activity of the organisms.

 The life cycle of biological bacteria inside the packing is long and rich, especially suitable for the growth of nitrifying bacteria, and both anaerobic and aerobic characteristics, nitrification and denitrification denitrification and nitrogen removal effect is obvious.

No need to support, easy to fluidize, save energy consumption.

 Appropriate specific gravity (0.97~0.98 before hanging the membrane, ~1 after hanging the membrane), so that the filler becomes floating state when stopping the gas, the aeration is in the suspension of the fluidized state, reducing energy consumption to a large extent.

 Packing free and smooth rotation, increase the impact on the water bubbles and cutting, crushing large bubbles, extend the residence time in the water, oxygen utilization can be increased by more than 10%, effectively reducing the energy consumption for pulling.
