Masters thesis: Ammonium Stripping of Landfill Leachate

Background

Ragn-Sells is a privately held corporate group operating companies in six countries. Since 1966, Ragn-Sells have been involved in waste management, environmental services and recycling. Ragn-Sells collect, treat and recycle waste and residual products from businesses, organizations and households. Moreover, Ragn-Sells operates several landfills and leachate treatment plants. Leachate that comes out from old landfills is mainly contaminated with nitrogen (concentration of N-tot is about 50 mg/l) while concentrations of metals are low. At these landfills, the leachate could be treated with stripper that removes nitrogen from the leachate.

Goal

Test and optimize a methodology for stripping N from landfill leachate

Project Description

Objectives:

  1. Perform a literature study and laboratory experiments on the removal of nitrogen from the landfill leachate with stripper. 
  2. Evaluate the efficiency of the stripper depending on different variables (or factors) such as pH, water and air flow, filling material etc.
  3. Prepare a suggestion for the stripper design on full scale 
  4. Perform techno-economic analysis (e.g. investments and operation costs).
