Abstract: Hydrophobic polymer particles (e.g., granules or fragments) employed as filter media, e.g., for filtering runoff water, include an antimicrobial compound on exterior surfaces and can reduce proliferation of microbial organisms as well as sorb chemical contaminants from the water. By employing this dual decontamination action, filter systems employing such particles can improve the quality of runoff water (or other contaminated water streams) and reduce the risk presented by potentially harmful organisms.

Abstract: A method for treatment of organic-based material comprising contacting the organic-based material with solid waste material from the treatment of cooking oils. The treatment may comprise a clean-up of said organic-based materials, particularly clean up of an oil spill on a body of water. The solid waste material may be applied directly to the oil or it may be placed in bags prior to placing it on an oil spill. The solid waste material from the treatment of cooking oils is the solid waste product used in the treatment of cooking oils and cooking fats for the purpose of removing undesirable compounds that affect flavour, colour and odour therefrom. The solid waste material from the treatment of cooking oils typically comprise particulate material, such as acid-activated clays, that are loaded with adsorbed compounds and contain residual oils from the treatment process.

Abstract: A structure (10, 44, 50) can be formed by using a plurality of hubs (12), connectors (14) and elongate members (16). The hubs (12) have a series of locking slots (18) formed at regular intervals about the outer circumference. A T-shaped portion (32) of a connector (14) is slid into a selected locking slot (18) until a flexible catch (34) on the connector (14) engages a locking bar (20) on the hub (12) to securely attach the connector (14) to the hub (12). Both the hubs (12) and connectors (14) can frictionally receive elongate members (16), allowing the construction of various types of structure, such as furniture. The structures can be assembled without tools, and can be readily be disassembled if desired.
