Abstract: A suspension-type packaging arrangement for a product includes an upper engagement section having an opening to receive a hook or the like, a lower product support section, and an intermediate display section located between the upper engagement section and the lower product support section. The product is secured to the product support section, and is exposed to allow the user to handle the product so as to evaluate and test the product prior to purchase. The upper engagement section and the lower product support section are configured so that the center of gravity of the product is generally in line with the location at which the hook engages the upper engagement section, so that the packaging arrangement and the product hang in a generally vertical orientation for display. The intermediate display section is defined by an outwardly facing wall, and may be configured to releasably secure a display card containing product information that is visible to the potential purchaser.

Abstract: A process and apparatus for membrane treatment of a feed liquid to form a product liquid includes feeding a feed liquid, typically an aqueous solution such as tap water, to a primary membrane. The primary membrane separates the feed liquid into a primary membrane retentate which is retained by the primary membrane, and a primary membrane permeate. The primary membrane retentate is then fed to one or more supplemental primary membranes, or to a secondary membrane. The primary membrane retentate (or supplemental primary membrane retentate if a supplemental primary membrane is employed) is separated by the secondary membrane into a secondary membrane retentate which is retained by the secondary membrane, and a secondary membrane permeate passes through the secondary membrane. The secondary membrane retentate may either be collected and disposed of, or may be fed to one or more supplemental secondary membranes.
