Two series of binary graft cationic starch-based flocculants (CS-DMCs and CS-DMLs) with
different hydrophilicity and charge density (CD) were prepared by graft copolymerization of …

Optimization of sludge conditioning and dewatering is a continuing challenge for wastewater
treatment plants. This study investigated the use of an in-line UV–vis spectrophotometer to …

Chemical treatment processes such as ozonation have mostly been considered as an
efficient way for bio-solids minimization. The improvement of sludge dewatering was more a …

This study introduces a novel method for estimating floc conditions in sludge dewatering
plants by employing image analysis and automatic control of polymer dosage. While …

A novel floc sensor prototype was tested in a Norwegian municipal wastewater treatment
plant. The resulting images of flocs, captured using a specially designed software, were …

Optical techniques are often used for the development of new monitoring systems for
wastewater quality. The different techniques, light scattering, UV-IR spectrophotometry …

For polymer induced flocculation processes, the effects of flow patterns in a gap of a conical
stirrer on aggregate formation and subsequent sludge dewatering efficiency were analysed …

In this paper, the influence of the polymer-induced flocculation on undigested sludge
dewatering is investigated by image analysis. The mixing of flocculants in a so-called rapid …
