With over 20 years of experience in manufacturing wastewater treatment equipment, our ISO 9001 and CE certified systems offer flexible configurations for municipal and industrial applications. Below you will find the key selection criteria between MBBR (Moving Bed Biofilm Reactor) and MBR (Membrane Bioreactor) technologies including auxiliary units.
Core Technology Comparison
1. MBBR Systems
Best for: High organic load, flow fluctuation sites (food processing, resorts)
Key Components: Biofilm carriers, fine bubble diffusers, secondary clarifier
Expandability: Add carriers to increase capacity 30% without new tanks
2. MBR Systems
Best for: Space-limited sites requiring reusable water (urban buildings, farms)
Key Components: Hollow-fiber membranes, suction pumps, chemical cleaning system
Output Quality: Directly meets WHO irrigation standards
Auxiliary Unit Integration
Enhance system performance with:
Dissolved Air Flotation (DAF): For oil/grease removal (meat processing plants)
Tube Settlers: Compact sedimentation for high SS wastewater
Sludge Scrapers: Automated sludge removal in rectangular tanks
Phosphorus Removal Units: Chemical dosing systems for nutrient control
5-Step Selection Framework
1.Analyze Wastewater Characteristics
COD/BOD ratio > 0.6? Choose MBBR for cost efficiency
Need ultrafiltration? Select MBR
2.Verify Certification
Demand ISO 9001 & CE Declaration of Conformity
Check test reports against local standards (e.g., EPA 40 CFR Part 133)
3.Auxiliary Unit Planning
High fat/oil content: Add DAF unit
Sludge disposal constraints: Include sludge thickener
4.Lifecycle Cost Calculation
MBR: Higher CAPEX, lower OPEX with water reuse
MBBR: Lower CAPEX, ideal for fluctuating loads
5.Request Factory Audit
Verify membrane MTR certificates (for MBR)
Inspect carrier media abrasion resistance tests (for MBBR)
