Faster Wetting of carriers resulting in better fluidization and homogenization of Fluidized bed . Hydrophilic nature of surface improves water binding ability of the carrier and thus helps maintaining bioactivity. Better mass transfer of substrates across the biofilm segments
High Inner Porosity and Fine Pore/Void Structure
Faster colonization during the initial bioprocess start up, protection of biomass against toxic shock loads, better diffusion gradients leading to development of a diverse community structure and composition based on the substrate gradient, growth of specific type of slow growing bacteria
Surface Roughness and Adsorbing Capacity
Development of highly active biofilms with better access to bulk liquid, good mass transfer resulting in better reaction kinetics and thus removal rates, protection against toxic substances.
Advantage of Ideal MBBR/ Attached growth carrier properties
Faster colonization and process start up
Lower degree of Filling required
Lower mixing energy requirement
Protection against toxic shock loads
Development of diverse bio community resulting in better process performance
Lower sludge production and better settling properties
