DEVELOPMENT OF DEWATERING AIDS FOR

2004-7-1  MCT has developed a suite of novel dewatering chemicals (or aids) that are designed to cause a decrease in the capillary pressures of the water trapped in a filter cake by (1) decreasing the surface tension of water, (2) increasing the contact angles of the particles to be dewatered, and (3) causing the particles to coagulate, all at the same time.

Use of surfactants to aid the dewatering of fine clean

1998-10-1  Apart from an improved dewatering kinetics, the filtration rate is also accelerated. The increase of dewatering kinetics leads to significantly lower cake moisture content even in the short time of dewatering, thus making the process more efficient. Because of lowered moisture content, air throughput rises correspondingly.

What is Dewatering, When is It Used, and Methods

2018-1-31  Usually, dewatering is a technique implemented on most construction sites because it helps retrieve water accumulated in trenches. This water needs to be removed in construction projects to keep working as planned and provide a safe work environment. Workers generally use water pumps to dewater

Certain dewatering aids have been used in the prior processes for dewatering. In some instances, the dewatering aid was not completely acceptable because it did not reduce the moisture content of the dewatered mineral concentrate adequately. In other instances, the dewatering aid was not substantially adsorbed on the dewatered mineral concentrate and contaminated the process water, which water is
