Unique Little Dirtflake: Performance of a Flocculation ...

The performance of a commercial flocculation agent on wastewater from the brown coal (lignite) mining industry was studied by laser diffraction using an Anton Paar Particle Size Analyzer (PSA). The particle size distribution, quantified by volume-weighted D50 values, shifted to larger sizes with increasing concentrations of flocculation agent.

2014-8-20  Shear flocculation and two-stage shear flocculation experiments. The shear flocculation experiments were carried out in a 400 cm 3 cylindrical cell with four baffles using 1 g solid and 300 cm 3 water. The mixture of solid-water suspension was pre-conditioned for 1 min in order to obtain a well-dispersed suspension.

Flocculation of Coal Waste Slurry Using Bioflocculant ...

2019-5-26  The flocculation technique is the most common sedimentation method for the dewatering of coal waste slurry, which is fine grained and has high ash content. Bioflocculants are flocculants which are vital to accelerating the settling of coal waste slurry via the flocculation technique. In this work, the bioflocculation of coal waste slurry was studied using a biofloccuant produced by Azotobacter ...
