Aggregation of Electrolysis-Treated Kaolin Suspensions Used to Simulate Raw Retentate

Influence of Particle Shape on the Viscosity of Kaolin Suspensions

The influence of particle shape (aspect ratio) on the intrinsic viscosity is investigated, taking three Czech kaolin products (floated kaolins) as paradigmatic examples. An average aspect ratio is obtained for each kaolin from a comparison of particle size measurements using sedimentation and laser diffraction. The intrinsic viscosity is obtained by a multistep procedure: firstly, flow curves a...

The deflocculation of kaolin suspensions - the effect of various electrolytes

The deflocculation effect of conventional additives to kaolin suspensions is evaluated from the results standard rheological measurements. Several widely used electrolytes (NaOH, Na2C03, Na2Si03, SHMP = sodium hexametaphosphate, and CMC = sodium salts of carboxymethylcellulose) have been tested. The optimal concentrations of these deffloculants, in respect to reaching the maximum reduction of i...

Electrolytic Aggregation Treatment without Coagulant Dosage for Retentate

Iris Cyst Treated Cy Electrolysis.

CYSTS of the uveal tract have been classified clinically as congenital, parasitic, exudative or degenerative, traumatic implantation, and spontaneous or idiopathic (Duke-Elder, 1940). There is considerable overlap between the last two groups and many cases which one suspects of being traumatic in origin give no history of injury. The tissue forming the cyst in traumatic cases has been implanted...

Engineering Characteristics of Chemically Treated Water-Repellent Kaolin

Water-repellent soils have a potential as alternative construction materials that will improve conventional geotechnical structures. In this study, the potential of chemically treated water-repellent kaolin clay as a landfill cover material is explored by examining its characteristics including hydraulic and mechanical properties. In order to provide water repellency to the kaolin clay, the sur...
