Abstract: A coalescing element for aggregating droplets of an emulsion. The coalescing element includes a nonwoven web substrate. A coalescer that includes the coalescing element can also include a housing and a fluid inlet and a fluid outlet each in fluid communication with the coalescing element. The coalescing element and coalescer may be useful for emulsions that form in solvent extraction/electrowinning copper processing and for other emulsions.

Abstract: Provided are methods and related compositions for separating immiscible organic and aqueous compositions. The methods include dispersing a discrete, insoluble filler in the organic composition, dispersing the organic composition into the aqueous composition, separating under gravity the organic and aqueous compositions into respective upper and lower layers. Advantageously, the insoluble filler remains in the organic composition and facilitates segregation and coalescence of droplets of the organic composition in the aqueous composition.
