  • Evaluation of natural zeolite for Ammonium and Phosphorus removal from tertiary treatment in urban wastewater plants 

    Aguirre González, Lidya (Universitat Politècnica de Catalunya, 2014-06)
    Master thesis (pre-Bologna period)
    Restricted access - author's decision
    In the present work was evaluated the capacity of natural zeolite for ammonium and phosphorus removal and recovery from residual effluents in tertiary treatments of urban wastewater plants. Two different natural zeolites ...
  • Infuence of zeolite structure and chemistry on the electrical response and crystallization phase of poly(vinylidene fluoride) 

    Lopes, Ana Catarina; Caparrós Vázquez, Cristina Maria; Ferdov, Stanislav; Lanceros Méndez, Senentxu (2012-11-21)
    Restricted access - publisher's policy
    Zeolites with framework types LTL, LTA, FAU, and MFI were synthesized and used as fillers to prepare PVDF/zeolite composites. The obtained composites showed structural and electrical dependence on the pore system and ...

  • Simultaneous ammonium and phosphate removal by metal inorganic salt modification of natural zeolite 

    Ventosa i Capell, Blanca (Universitat Politècnica de Catalunya, 2015-01)
    Bachelor thesis
    Open Access
    Nutrients discharge into receiving waters can cause an environmental problem capable of deathly altering ecosystems. Natural zeolites are low cost resources with ion exchange capacity that have been widely studied. This ...
  • Simultaneous phosphate and ammonium removal from aqueous solution by a hydrated aluminum oxide modified natural zeolite 

    Guaya, Diana; Valderrama Angel, César Alberto; Farran Marsà, Adriana; Armijos, Chabaco; Cortina Pallás, José Luís (2015-07-01)
    Restricted access - publisher's policy
    A natural zeolite (Z-N), rich in clinoptilolite, was modified (Z-Al) by incorporation of hydrated aluminium oxide (HAlO) for the simultaneous phosphate and ammonium removal. The incorporation of surface hydroxyl groups ...
  • Synthesis of zeolites from coal fly ash: an overview 

    Querol, Xavier; Moreno, N.; Umaña, J.C.; Alastuey, A.; Hernández Chiva, Emilio; López-Soler, A.; Plana, F. (2002-05-02)
    Restricted access - publisher's policy
    Coal combustion by-products production in USA and EU is estimated in around 115 million tons per year. A large portion of this production is accounted for the coal fly ash (CFA). Cement and concrete manufacturing consumes ...
  • Zeolite-coated interdigital capacitors for humidity sensing 

    Urbiztondo, M.; Pellejero, I.; Rodríguez Martínez, Ángel; Pina Iritia, María Pilar; Santamaría Ramiro, Jesús Marcos (2011-05-06)
    Restricted access - publisher's policy
    Inter-digital capacitors (IDCs) with electrode gaps of 10 or 50 microns have been coated with zeolite films consisting of different zeolites with Si/Al ratios ranging from 1.5 (zeolite A) to infinite (silicalite). The ...
