LSF denitrification technology is a highly promising biochemical process for treating total nitrogen. The principle of this process involves microbial communities using denitrification filter media as an electron donor. When the wastewater to be treated enters the LSF reactor, nitrogen salts in the wastewater are broken down under the action of microbial communities, thereby achieving the removal of total nitrogen from the wastewater at a relatively low treatment cost.

Technical Advantages

(1) Chemically stable, long lifespan, and reusable;

(2) No addition of any chemical agents and no energy consumption;

(3) Short retention time and fast degradation rate;

(4) High degree of automation in operation and low treatment cost;

(5) Supporting facilities can be designed as structural or equipment-based according to scale and user requirements, meeting various needs.
