Abstract: A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portions—each communicating with flow from one of the flow modifiers. The device can include one or more plates disposed adjacent one another within the internal hollow with a peripheral edge attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or one or more of the plates can define openings therein allowing passage of at least some fluid therethrough.

Abstract: A saturated layer stormwater filtering system with down-flow layered multimedia filters is disclosed. The filtering system may include an upflow pretreatment chamber and a subsequent filtration chamber. It also includes a snorkel pipe as an adjustable head control or internal baffles. The system incorporates gravity powered partially saturated stormwater media filters to harness the potential energy of stormwater from downspouts and pumped flows from stormwater catchments to drive the polluted stormwater in a hydraulically controlled fashion by gravity through a series of filter media layers.

Abstract: A filtration device designed for the purpose of recovering filtrate from wastewaters is characterized by a rotor system (2) that is drivable in rotary manner about a horizontal axis (5) in a liquid bath in a receptacle (1), and which serves as the support for multiple assemblies (17) of filter discs, the interior spaces of which are connected to the suction side of a pump (39) via a collection chamber (29). The liquid to be filtered is transported with the aid of a pump (40) that is connected to a plurality of distributor lances (35) that extend parallel to and close to the hollow shaft (21) that supports the rotor system (2) via a line (31) with the interposition of a prefilter (41) that is intended to separate a coarse fraction. The central introduction of the prefiltered liquid distributed evenly over the length of the rotor system (2) via the distributor lances (35) in conjunction with a network (36) of lines designed to introduce air bubbles into the liquid bath and located in the bottom of the receptacle (1) results in a stable operation that also suppresses the formation of deposits and engenders high and consistent filter efficiency.

Abstract: The invention is a portable external modular filtering and contamination removal system for a ship. A plurality of non-fixed position modular filter assemblies filter and remove macro-, micro- and nano-particle contaminates ship-side. The filter assemblies may be vessel-based or port based. A floating access and maintenance unit provides easy access to the filter assemblies. The filter assemblies move in cooperation with each other to spread the discharge over multiple units. A flow collecting and diverting apparatus seals against the ship to prevent discharge from running down the side of the ship with a directional discharge to divert discharge to waiting filter assemblies. The filter assemblies may provide their own buoyancy, obtain some buoyancy from vertical support lines from the deck of the ship or shift the buoyancy needs partially or wholly to the floating access and maintenance unit.
