摘要： An improved canister for the recovery of silver from acidic, waste fluids is described. This canister comprises both inner and outer element, each removable from the other, with fitted top and bottom sections. The novel canister thus described, provides a rapid flow of waste material through the system and is efficient and easy to use and manufacture than prior art elements. Plugging of the canisters due to intermittent use is also reduced in the element of this invention.

摘要： Methods for surface treatment of polyester substrates are described. Treatment methods include adherence of a polymer layer on a surface of the polyester so as to increase the hydrophilic properties of the surface. Polymers can be polyelectrolytes that are adsorbed at the surface or polymer brushes that are polymerized at the surface. Further surface functionalization can include the adherence of inorganic nanoparticles to the surface. The polyester substrates can be recycled polyester such as recycled polyethylene terephthalate that has been subjected to a partial saponification reaction during the recycling process.

摘要： A method for separating polyester materials from contaminants is disclosed suitable for, for example, a polyester recycling system. The method is a dry separation method and includes rapidly spinning a mixture of polyester and contaminants within a cleaning chamber. During the spinning of the mixture, the contaminants can be degraded and pass through a screen at the chamber wall while the polyester materials are not substantially degraded and can remain in the cleaning chamber. Polyester fines can also remain in the cleaning chamber. A cleaning device suitable for use in the process is also disclosed. The device can include a screen of a hardened material that can help degrade the contaminants and a plurality of rotating blades that can spin the mixture within the device and can also help to degrade the contaminant materials.
