Abstract
An apparatus for removing mineral particles from loaded engineered collection media includes one or more solvents with sufficiently low surface tension. The engineered collection media are made of a synthetic material and have a surface coated with a hydrophobic material to provide a chemical bond between the mineral particles and the surface. The solvents together with a releasing mechanism are arranged to disrupt the chemical bond. Preferably, a surfactant or a nonionic surfactant is also added to the solvents.
