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/Viod 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 strcture 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 efficiency
  • Lower sludge production and better settling properties
