LEQUIA doctoral thesis explores the removal of odour causing compounds through waste generated in wastewater treatment and power plants

Carla Canals Batlle, former researcher of LEQUIA group will present next Friday 30th November her doctoral thesis entitled “Adsorbentes preparados a partir de residuos y su aplicación en la eliminación de compuestos causantes de olores (NH3 y H2S)”. The thesis was supervised by Dr. María J. Martín Sánchez and Dr. Miguel Ángel Montes Morán and will be defended at 11:00h at “Sala d’Actes” of Escola Politècnica Superior (Building IV) of the University of Girona.


Research work addresses two environmental challenges: waste management (sewage sludge and fly ashes from power plants) and the removal of odour causing compounds (ammonia and hydrogen sulphide).

Carla Canals’ doctoral thesis explores isolation of adsorbent materials through two types of waste – sewage sludge and fly ashes from power plants – and evaluates the capacity of those new materials to remove ammonia and hydrogen sulphide. Concretely, the thesis focus on chemical activation with sodium hydroxide (NaOH) and potassium hydroxide (KOH) from sewage sludge of two waste water treatment plants in Girona province through both conventional heating and microwave. On the other hand, the isolation of adsorbent materials through electromagnetic energy (microwave) with sludge and fly ashes from a co-firing (coal and biomass) power plant located at Tilbury (United Kingdom) is also studied.

The thesis is framed within one the main research lines of LEQUIA: advanced oxidation-adsorption processes for the treatment of liquid and gaseous effluents, directed by Dr. María J. Martín Sánchez.
