Ideal MBBR/ IFAS carrier properties

Ideal MBBR Carrier Properties	Benefits / Key Attributes to MBBR Process
Hydrophilic surface of material and density	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.
