Cork boiling wastewater management by anaerobic digestion
Gonçalves, M. R.; Gil, Luís; Marques, Isabel PaulaCork boiling wastewater (CBW) is an aqueous and complex effluent of the cork industry which is produced during the boiling of the cork planks, one of the key operations in cork processing for cork stoppers production. CBW contains suspended and dissolved solids and organic materials such as phenolic compounds and is characterized by a low biodegradability and an acid pH. This boiling wastewater has no utility, ...
Mineralization of olive mill wastewater over DSA
Gonçalves, M. R.; Correia, J. P.; Marques, Isabel PaulaBioenergy recovery from olive mill wastewater (OMW) has been effectively accomplished by anaerobic digestion [1]. Nevertheless, a post treatment is required to attain the discharge limit values. After the anaerobic treatment of OMW, the main issues are related to the remaining organic matter (COD), recalcitrant phenolic compounds (40-50%) and effluent dark-brown colour. The electrochemical treatment is proposed...
Start-up and feeding strategy of an anaerobic sequencing batch reactor for oliv...
Costa, J. C.; Gonçalves, M. R.; Marques, I. P.; Alves, M. M.Olive mill wastewater (OMW) is the effluent generated by olive oil industries, mainly produced in the Mediterranean areas. The production of olive oil generates huge amounts of wastewater. Anaerobic wastewater treatment processes appears as a promising technology for the treatment and energetic potential recovery of these high strength wastewaters since a renewable energy source (biogas) is generated. However, ...
Microscopia de varrimento por sonda (SPM)
Limão-Vieira, P.; Gonçalves, M. R.; Ribeiro, J. H. F.Gazeta da Física • VOL. 18 • Fascículo 4; A invenção do Microscópio de Efeito de Túnel (Scanning Tunneling Microscope) em 1981, por G. Binnig e H. Rohrer, seguida do aparecimento do Microscópio de Força Atómica, em 1986, conduziu ao desenvolvimento de um conjunto de novas técnicas de microscopia, genericamente designadas por Microscopias de Varrimento por Sonda (Scanning Probe Microscopy ou SPM). Os avanços con...
