    Abstract: A static screen has a plurality of screening bodies and a plurality of aeration devices downstream of the screening bodies. Each aeration device is associated with a set of one or more of the screening bodies. Each aeration device may be a pulsing aerator. The pulsing aerators do not all release air at the same time. Each screening body works through periods of dead end filtration separated by backwashing events. The backwashing events comprise introducing a slug or pulse of air into the bottom of the screening body. Flow through the static screen continues at all times because the screening bodies are not all backwashed at the same time. The static screen may be used to remove trash from water flowing to an immersed membrane unit. Alternatively, the static screen may be used to provide primary wastewater treatment.

    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.
