Low-Sludge-Production Biological Biofilm Wastewater Treatment Process (abbreviated as LSP Process)
Low Sludge Production——Biological Ladder Biofilm Process
Through systematic compartmentalization and the unique properties of a proprietary nano‑biocarrier packing material, microbial flocs, protozoa, metazoa, and aquatic animals are progressively enriched in distinct zones, fostering a stepwise, mutually beneficial integration of biological and food chains, ultimately achieving a substantial reduction in the volume of activated sludge.
