    Abstract: Apparatus in fluid communication with a water leg portion of a hydrocarbon-contaminated water, e.g., a water leg portion of an offshore drilling or production platform sump tank for conveying water, separated from oil, into contact with organophilic media canisters such that the hydrocarbons and other organic materials commingled with the sump tank water will be adsorbed onto the organophilic media and detected by the embedded probe in selected canisters. The canisters are provided in a plurality of stacks and are in fluid communication with a header disposed at the bottom of the vessel housing the various stacks of canisters. Solids that do not pass through the canisters are accumulated at the bottom of the vessel and easily drained through a drain port. The water will pass through the media and will be conveyed back to the ocean water without contamination. At some point in time, the organophilic media will become “spent” and at a certain “spent level”, the saturated condition of the organomedia will be electronically detected by the embedded probe and alarm/control panel. The alarm indicates that the “spent” organophilic media should be replaced with fresh media or the spent media regenerated.

    Abstract: Apparatus and for the treatment of storm water runoff to remove contaminants that accumulate in the storm water when it flows over paved surfaces in urban areas. The apparatus includes a basket that has an outer surrounding water-permeable wall, and an inner water-permeable wall, spaced from and surrounded by the outer wall. A bed of an absorbent, able to absorb contaminants in the storm water, is disposed in the space between the outer and inner walls, while allowing fluid communication between the walls. An inner drainage space is defined by the inner wall and is in fluid communication with the absorbent. During operation, storm water flows through the outer permeable wall, into the bed where it is treated; and treated water flows from the bed through the inner wall into the inner drainage space. Treated water then flows from the drainage space, in some embodiments under a siphon-effect, into a treated water drainage conduit for disposal. The absorbent may be selected from compost, vermiculite, activated carbon, peat, ion exchangers, clays, and the like, and may be in the form of pellets or particulates. The baskets are of modular construction so that the beds are in containers that may be removed and replaced, with minimal labor. Moreover, the baskets may be backflushed to remove particulates and debris that clog the beds and retard the treatment rate.

    Abstract translation: 用于治理雨水径流的装置，用于清除在城市地区流过铺面的雨水中累积的污染物。 该装置包括一个具有外部周围的可透水壁的篮子和与该外壁隔开并被外壁包围的内部透水壁。 能够吸收暴雨水中的污染物的吸收剂床设置在外壁和内壁之间的空间中，同时允许壁之间的流体连通。 内部排水空间由内壁限定并与吸收剂流体连通。 在运行过程中，雨水流过外部可渗透壁，进入被处理的床; 处理过的水从床层通过内壁流入内部排水空间。 然后处理的水在排水空间中，在一些实施例中在虹吸效应下流入经处理的排水管道以进行处置。 吸收剂可以选自堆肥，蛭石，活性炭，泥炭，离子交换剂，粘土等，并且可以是颗粒或颗粒的形式。 篮子采用模块化结构，使床位在可以拆卸和更换的容器中，劳动极少。 此外，可以将篮子反冲洗以除去堵塞床的颗粒和碎屑并延缓处理速率。
