Product Introduction
1. System Classification by Microbial Growth Morphology
Wastewater biological treatment systems can be fundamentally categorized into two types based on microbial growth morphology:
Suspended growth systems (e.g., activated sludge and MBR)
Biofilm systems (e.g., trickling filters, fixed biological media, and MBBR)
2. Comparative Advantages and Disadvantages
Biofilm Reactors:
Advantages:
High tolerance to environmental fluctuations and toxic substances
Superior organic loading capacity
Key Technological Advantages:
Combines benefits of both systems:
High-load capacity of biofilm systems
Stable treatment performance
Excellent mass transfer characteristics of activated sludge
Continuous carrier movement ensures:
Uniform biofilm-water contact
Enhanced mass transfer efficiency
