Innovative LINPOR Process for Sludge Recycling Using Hybrid Flexible Foam Carrier Media

DESCRIPTION

The LINPOR process introduces a hybrid method for sludge recycling, utilizing flexible foam as carrier media. This advanced technique integrates a conventional Modified Ludzack-Ettinger (MLE) process scheme with pre-anoxic zones for dissolved oxygen reduction and denitrification. An oxic zone ensures optimal solids retention time (SRT) for effective nitrification, while post-anoxic options are available as needed. Key benefits include simultaneous denitrification, reduced carbon requirements, and energy-efficient fine bubble diffusion leading to low solids volume indices (SVIs).

FOAM MEDIA
Why Flexible Foam? • Fundamental Differences • Structure • Open Channels, High Void Volume • Protected interior • Near neutral buoyancy • Biomass • Dense Floc, not Slime • Anoxic Core • Make for Key Advantages
