Abstract: Oil-absorbent skimmers of the present invention include an upper oil-absorbent flotation head that floats on water and several absorbent strands attached to the underside of the flotation head. The flotation head has a liquid-permeable cover with absorbent strips inside. The absorbent strips and strands are made of oil-absorbing materials that resist absorption of water. The passive oil-absorbent skimmers may be free-floating and may be used in stormwater catch basins, water holding tanks, vaults, sumps, bilges and the like for capturing hydrocarbons such as oil and oil-based liquids.

Abstract: Stormwater drain inserts that reduce or eliminate environmental runoff during rain storms and the like are described. The stormwater drain inserts are water permeable, but capture sediment, hydrocarbons, heavy metals and other contaminants. The stormwater drain inserts are adjustable in size in order to fit into various sizes of storm drain chambers, resting on the lip between the top grate and the chamber. The stormwater drain inserts include a top bib with a central sediment bag extending downward therefrom. Overflow ports are provided in the sediment bag, and an inwardly extending overhang ring directs incoming water flow away from the overflow ports as it enters the sediment bag. The top bib, sediment bag and overhang ring may be made of water permeable oleniphilic fabric that helps trap oils and other hydrocarbons.

Abstract: Multiple-tube stormwater filter socks may be used to mitigate stormwater environmental runoff of sediment, hydrocarbons and heavy metals. The stormwater filter socks comprise at least two tubes that are spaced apart by a separator web, and are filled with different types of absorbent media. The stormwater filter socks may be placed around the top grate of a storm drain chamber, and around other environmental runoff sources such as trash bins, roof downspouts and outdoor material stockpiles. The multiple-tube stormwater filter socks may be used to mitigate drips and spills of hydrocarbons such as motor oils, and may be used to contain zinc, copper, lead, chromium, cadmium and other heavy metals.
