LIFE LEACHLESS

Treatment model that uses a technology that combines solar evaporation with direct osmosis.

Description

Large amounts of leachates are generated in Europe and, because of their composition, having a high pollution load. The LEACHLESS project proposes a treatment model that will be carried out “in-situ” using a cost-effective novel technology that combines solar evaporation/condensation plus forward osmosis. The prototype will be powered by renewable energies, which will minimise the carbon footprint of the process.
 
The final effluent quality will be very high, allowing reuse (preferred) or discharge into watercourses. A minority semi-solid residual stream will be also generated in the process. That stream will be valorised in ceramic industries to improve the final products characteristics.

 

Objectives

  • To demonstrate the technical and economic feasibility for leachate treatment.
  • To valorise highly pollutant effluents by completely reuse of the streams.
  • To provide a cost-effective process for leachate treatment.
  • To replicate this model in facilities of two European countries.
  • To promote the transferability of the model to other facilities.
  • To encourage the stakeholders in the Water Directive implementation.

Actions

  • Characterisation of leachate streams.
  • Optimising the operating conditions of the technologies at lab scale and energy integration analysis.
  • Prototype design, construction, start-up, validation and operation.
  • Assessment of effluent and sludge quality according final use.
  • Monitoring the environmental and socio-economic impact of the project.
  • Public awareness and dissemination of results.

Expected results

  • Treatment up to 8 m3/day of leachate
  • Obtaining a high quality final effluent that can be reused or discharged into the watercourses.
  • Reduce the cost of leachate treatment by more than 80%.
  • To eliminate the need of leachate transport leachate to WWTPs.
  • Improving the operation of landfills and reducing the associated environmental impact.
  • 100% valorisation of the by-products generated in the process.
