TL;DR: The hypothesis of this paper is that dispersion could be quantified through the classification of aggregates detected in transmission electron microscopy images using k-Means to classify image particulate elements of five CNC samples into groups according to their geometric features.

TL;DR: In this article, a polyaluminium nitrate sulfate salt combined with a quaternary polyamine has been evaluated in a long-term industrial trial for assessing its potential benefits, and the results indicate that this new chemical is able to improve the removal of contaminants by dissolved air flotation, especially when the contamination load of the waters is high, allowing a further closure of the water circuits.

TL;DR: In this article, a real-time methodology for flocculant selection in the fibre-cement manufacture based on studying flocculation and floc properties with a focused beam reflectance measurement (FBRM) is described.

TL;DR: In this paper, the feasibility of the recovery of the metals from stainless steel waste pickle baths by precipitation is studied, and an overall method is proposed, consisting of precipitation and briquetting, giving products with adequate mechanical properties and composition.

TL;DR: Results showed that TEMPO-mediated oxidation as the cellulose pretreatment is a key factor to obtain the grafted polymer CNF-g-CH, which was used as a promising material to remove water-based inks and dyes from wastewater.
