Estimating the Shear Resistance of Flocculated Kaolin Aggregates

Figure 2 shows the flocculation kinetics of clay suspensions in seawater (high salt) at polyacrylamide doses of 13, 34, and 89 g/t and industrial water (low salt) at 89 g/t at a shear rate of G = 273 s ?1. Once the flocculant is added, the growth of the aggregates is practically instantaneous, and it only takes a few seconds to reach a

Moreover, the CIS flocculant showed excellent flocculation effects in ambient pH of 4¨C10, flocculation temperature of 10¨C40 ¡ãC, and various inorganic salts. In general, the anionic CIS flocculant shows excellent cost effectiveness, where the predicted operation cost of as-prepared CIS is about 60 % of conventional polyacrylamide flocculant.

A cost-effective anionic flocculant prepared by grafting

The flocculation mechanism is single charge neutralization. Moreover, cost evaluation shows the treatment cost of CAL is 68.3% lower than that of commercial anionic PAM. The anionic flocculant CAL has the advantages of easily available materials, cost effectiveness and excellent flocculation performance.

Competition between kaolinite flocculation and stabilization

Anionic PAMs, which can be thought of as synthetic analogs of extracellular polymeric substances, have been used widely as flocculating agents to control soil erosion and sediment runoff from source sites and to remove suspended solids in water and wastewater treatment processes ( Roa-Espinosa et al., 2000; Lentz et al., 2002; Lu et al., 2003; M...

Water Soluble Polymer Flocculants: Synthesis, Characterization,

Because of the low critical free adsorption energy of polymer chains on the particle surfaces, in the order of about 0.3 kT per segment, 6 the rate of polymer adsorption equals the rate of polymer loss from the solution, which explains the significant role of mixing in flocculation.

A Review on Coagulation/Flocculation in Dewatering of Coal Slurry - MDPI

Flocculation of ?75 ¦Ìm coal fines in coal slurry is achieved using nonionic Nalco-83370 + flocculant [ 40 ]. The flocculation performance results in a maximum settling rate of 0.3222 cm/s with a turbidity reduction ratio of 99.02% (having residual turbidity 41.7 NTU) [ 40 ].

Lime/Sodium Carbonate Treated Seawater to Improve Flocculation

A common flocculant is a high molecular weight anionic polyacrylamide (A-PAM), which generates high sedimentation rates when applied at relatively low doses [8,9,10]. Currently, several mining operations use seawater in their processes, either directly or after desalination by reverse osmosis [ 2 , 11 ].
