Low-Sludge-Production Biological Biofilm Wastewater Treatment Process (referred to as the LSP Process)
Product Description
Divided-flow baffle design
- Through systematic compartmentalization and the unique properties of a specialized nano‑biocarrier packing material, microbial flocs, protozoa, metazoa, and aquatic organisms are progressively enriched in distinct zones, fostering a stepwise, mutually reinforcing integration of biological and food chains. This ultimately achieves a substantial reduction in organic sludge—sludge volume can be cut by more than 95%—effectively addressing the challenges of sludge disposal.
- Anaerobic, anoxic, and aerobic microorganisms are stratified and enriched within the nanofiber carrier packing, enabling nitrification and denitrification to occur in their respective microenvironments and thereby enhancing total nitrogen removal efficiency.
Core material
- The biological abundance and diversity enriched on the proprietary filler are far higher than those achieved by technologies based on similar principles.
- The fiber‑carrier packing features nanoscale filament diameters; its unique structure gives it an exceptionally high aspect ratio (22,500:1) and a specific surface area of ≥20,000 m²/kg, providing an optimal growth environment for microbial attachment.
- The fibrous carrier packing has been modified to enhance its bioaffinity and non‑electrostatic properties, thereby improving dispersibility and interfacial adhesion. The microbial attachment capacity is 3–8 times greater than that of conventional carriers, with a microbial concentration reaching 15,000–30,000 mg/L.

LSP Technology: Application Scenarios and Advantages
High organic sludge reduction
Organic sludge reduction can exceed 95%.
Low operational energy consumption
Aeration rates are progressively reduced, and carbon source dosing is decreased, resulting in an overall energy consumption reduction of approximately 15%–25%.
It’s hard to explain—substance removal rate is high.
It significantly enriches aquatic and metazoan organisms, resulting in higher treatment efficiency for wastewater with poor biodegradability and a low B/C ratio.
It enables retrofitting without halting production.
Modular, lift‑up design for rapid assembly, enabling retrofitting without production shutdowns.
Strong resistance to shock loads
The abundance and diversity of microbial species enable it to withstand fluctuations in both the quality and quantity of wastewater.
High total nitrogen removal rate
Nitrification and denitrification reactions occur within their own microenvironments, thereby enhancing the overall nitrogen removal efficiency of the local environment.
SS removal performance is good.
The effluent at the outlet of the LSP tank may not require sedimentation; the water quality is clear, with low suspended solids.
The core material has a long service life.
The core material has a service life of over 10 years, requires no backwashing, and is easy to maintain on a daily basis.
