Closure of water circuits in papermaking is of vital importance for achieving a more sustainable and economic manufacturing of paper. The most important limiting factor for a further closure is the accumulation of dissolved and colloidal materia[...]texto impreso
Blanco Suárez, Ángeles ; Negro Álvarez, Carlos Manuel ; Fuente González, Elena de la ; Sánchez, Luis Miguel | Romanian Academy | 2008The present paper, contributing to solving two different problems related both to the chemical industry and the environment, is a feasibility study on the utilization of the deinking sludge (the most important waste from papermaking) as a raw ma[...]texto impreso
El objetivo de la investigación que se presenta en esta memoria es proponer un procedimiento para tratar las lejías residuales procedentes del decapado del hierro en bandas con ácido clorhídrico, en el que se recupera el hierro en forma de pigme[...]texto impreso
Jarabo, R ; Monte Lara, M. Concepción ; Blanco Suárez, Ángeles ; Negro Álvarez, Carlos Manuel ; Tijero Miquel, Julio | Elsevier | 2012Nowadays, certain components of non-wood annual plants such as corn stalk and industrial hemp core are considered waste materials or used in low value applications; both by-products have a very low cost. On the other hand, given the large quanti[...]texto impreso
Jarabo, Rocío ; Monte Lara, María Concepción ; Fuente González, Elena de la ; Santos, S.F. ; Negro Álvarez, Carlos Manuel | Elsevier | 2013In the last few years an increasing high interest has been drawn to the potential use of agricultural waste as raw material to produce structural reinforcement fibers for building materials, due to environmental and economical aspects. Corn is t[...]texto impreso
Monte Lara, M. Concepción ; Blanco Suárez, Ángeles ; Negro Álvarez, Carlos Manuel ; Tijero Miquel, Julio | Elsevier | 2004Due to trends in papermaking like closed water systems or higher use of recovered paper as raw material, a large number of contaminants are accumulated in the system as dissolved and colloidal material (DCM). When the DCM is destabilized by a su[...]texto impreso
Blanco Suárez, Ángeles ; Miranda Carreño, Rubén ; Negro Álvarez, Carlos Manuel ; García Suárez, Concepción ; García-Prol, Marta ; Sánchez, Álvaro | 2007To ensure paper machine runnability, trouble-free converting, and high quality products, stickies must be removed during stock preparation of recycled pulp. However, the stickies removal efficiency along the process is not easy to assess since t[...]texto impreso

Monte Lara, María Concepción ; MacNeil, Donald ; Negro Álvarez, Carlos Manuel ; Blanco Suárez, Ángeles | WALTER DE GRUYTER | 2010Mixtures of stickies-containing and stickies-free pulps were investigated for their deposition potntial in an attempt to better understand the interactions of dissolved and colloidal material (DCM) when mixing two different pulps. The filtered p[...]texto impreso
Miranda Carreño, Rubén ; Negro Álvarez, Carlos Manuel ; Blanco Suárez, Ángeles | American Chemical Society | 2009New chemicals, based on the synergistic effect between inorganic polyaluminium salts and organic cationic polyelectrolytes, have been tested for the chemical optimization of a dissolved air flotation (DAF) unit, used as internal treatment of pro[...]texto impreso
New chemicals, based on the synergistic effect between inorganic polyaluminium salts and organic cationic polyelectrolytes, have been tested previously at laboratory-scale, and the most efficient product has been selected for an industrial trial[...]texto impreso
Merayo Cuevas, Noemí ; Hermosilla Redondo, Daphne ; Negro Álvarez, Carlos Manuel ; Blanco Suárez, Ángeles | Elsevier | 2013The efficiency of advanced oxidation processes is usually optimized by measuring the evolution of some water quality parameters sampling aliquots at pre-selected time intervals, such as particular undesired contaminants contents, or the reductio[...]texto impreso
Blanco Suárez, Ángeles ; Fuente González, Elena de la ; Monte Lara, María Concepción ; Cortés, Noelia ; Negro Álvarez, Carlos Manuel | 2009This paper presents the effect of the structure of cationic polyacrylamides (CPAMs) on flocculation of pulp suspensions and floc properties. A focused beam reflectance measurement (FBRM) probe was used to monitor flocculation, deflocculation, an[...]texto impreso
