This paper presents a Machine Vision System developed for on-line visual pulp inspection under the critical lighting requirements of the UNE-ISO 5350-2 standard. These requirements typically result in a very low dynamic range in the electronic images due to the following: high-speed displacement of the product (up to 2.7m/s), very high resolution (0.004mm 2 /pixel), and the backlight requirement...
The use of microfiltration to eliminate colloidal suspended matter (pitch) from different streams in the pulp production process can lead to the increase of pulp quality as well as the reduction of some problems associated to the accumulation of such matter in the process. Previous studies [1] have aimed at the treatment of white waters and diluted black liquors, the results being successful though...
