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.
Test and optimize a methodology for stripping N from landfill leachate
- Perform a literature study and laboratory experiments on the removal of nitrogen from the landfill leachate with stripper.
- Evaluate the efficiency of the stripper depending on different variables (or factors) such as pH, water and air flow, filling material etc.
- Prepare a suggestion for the stripper design on full scale
- Perform techno-economic analysis (e.g. investments and operation costs).
Required: chemical engineers or process engineers with good knowledge in fluid mechanics, thermodynamics and unit operations
