TOTAL NITROGEN (TN) REMOVAL: DENITRIFICATION

Applications

Integrating Lagoon Technologies to Solve Every Treatment Challenge from Influent to Effluent

Nitrate-nitrogen (NO3) is converted to nitrogen gas biologically in a low-oxygen (anoxic) environment when nitrogen gas escapes out of wastewater into the atmosphere. An excess of nitrogen can cause increased plankton growth and triggers algae blooms. Algae then causes a range of issues that impair wastewater treatment efficacy and efficiency, ultimately unable to meet increasingly stringent wastewater treatment requirements. By causing an increase in BOD and TSS of effluent, final effluent limits are unable to be met. In addition, issues such as an increase in odor requires an optimized and comprehensive solution. 

 

Total Nitrogen Removal

Following the LPR, denitrification is accomplished via carbon addition and filtration. The LemTec  up-flow sand filter consists of in‐ground up‐flow biologically active filters and of modular components that can be sized to meet the requirements of the project. Carbon enhancement is accomplished by the introduction of a soluble carbon source into the wastewater ahead of the filter. Bacteria metabolize the carbonaceous material in the wastewater as its food source, and consume the oxygen in the nitrate, releasing nitrogen gas into the air. 

Expertise as a leader in this industry for 30+ years, an arsenol of cutting-edge technologies and a groundbreaking approach set LET apart by delivering optimized solutions for wastewater applications including Denitrification to meet clients' objectives efficiently and cost-effectively. 

 

We maximize LET's innovative technologies as stand-alone solutions or use the Advanced Integrated Lagoon Technologies (AILT) approach to design and create the best process with technologies integrated as components that successfully meet every challenge from influent to effluent.
