Svi5/svi30
Web30 mag 2024 · The Nereda process incorporates a novel method of producing granulated sludge possessing an SVI5 = SVI30 i.e. a fast-settling sludge biomass. They used hydraulic selection pressure to select fast settling flocs and biotechnological processes to select extracellular polymeric substances (EPS). These include phosphate accumulating … WebFor instance, a SVI30 (sludge volume index) of 80 to 120 is considered appropriate for an activated sludge process and this value is usually lower than its SVI5. However, the SVI30 of aerobic granules could be around 47 and this value is usually similar to its SVI5. This indicates the excellent settling ability of aerobic granules.
