Abstract
The present disclosure relates, according to some embodiments, to methods, systems, and apparatuses for dewatering solid particles in a liquid mixture, such as those, for example, comprising receiving a liquid mixture, the liquid mixture including solid particles; suspending a filter in the liquid mixture; agglomerating, at the filter, solid particles in the liquid mixture, the agglomerating including potentiating passage of liquid in the liquid mixture through the filter and potentiating accumulation of solid particles in the liquid mixture to collect and agglomerate at the filter; and applying a shockwave to the filter, the applied shockwave operable to remove the agglomerated solid particles from the filter.
Claims6
A method of dewatering solids comprising the steps of:
- submerging a filter having a plurality of pores and defining an interior volume, in a liquid mixture comprising a liquid and a plurality of solid particles;
- applying a suction force to the interior volume of the filter, causing the liquid to pass through the pores and into the interior volume of the filter while preventing the solid particles from passing through the pores, the solid particles agglomerating and forming a cake on an exterior surface of the filter;
- raising the filter out of, and above the liquid mixture while continuing to apply the suction force to the interior volume for 10-12 seconds after the filter is raised above the liquid mixture;
- terminating the application of the suction force to the interior volume of the raised filter after the 10-12 seconds have passed;
- and
- applying shockwave pulses at a pressure of about 10 psi for a duration ranging from about 0.5 seconds to about 1 second to the filter while the filter is raised above the liquid mixture and after the application of the suction force is terminated, causing the cake to become dislodged and fall from the filter.
