Abstract: The present disclosure provides systems and methods that can treat feeds with elevated organic levels, e.g., feeds with ?300 Pascals (Pa) organic osmotic pressure, with one or more enhanced filter membrane modules, which may be referred to herein as membrane modules or simply modules. Preferably, a filter membrane module consistent with the present disclosure include one or more plate and frame modules, one or more spiral format modules, or a combination of plate a frame and spiral format modules. The systems and methods provided herein can provide reliable performance when used to treat feeds with elevated organic levels.

Abstract: The present disclosure is directed to filtering technologies that combine elements of continuous and batch NF/RO based on the constraints of the end-user facility to achieve a target balance between, for instance, recovery and power consumption, and to reduce long term operating cost of a plant. A method for extending batch operation into a second induction period with antiscalant injection is also disclosed herein, with the second induction period allowing for yet higher water recovery.

Abstract: A method of densifying a bulk particulate material includes at least partially confining the bulk particulate material, and mechanically agitating the confined bulk particulate material with at least two elongate rotatable members (14), (15) of which at least one is submerged in the confined bulk particulate material. The rotatable members each have an axis of rotation and include a plurality of axially spaced agitating formations (40) which project outwardly away from their axes of rotation. The rotatable members are transversely spaced.

Abstract: A method of operating an evaporative cooling tower includes contacting water with air in a cooling zone to cool the water and heat the air and cooling the heated air to condense water therefrom, thereby to reduce water loss from the cooling tower. Typically, the cooling of the heated air is by means of evaporative cooling employing a refrigerant.

Abstract: A method and corresponding apparatus for ranging an Optical Network Terminal (ONT) in a Passive Optical Network (PON) is provided. An example method may include: (i) transmitting a ranging request from an Optical Line Terminal (OLT) to an ONT in connection with a transport layer ranging window; (ii) monitoring for a ranging response from the ONT during at least one physical layer ranging window within the transport layer ranging window, the transport layer ranging window having a duration longer than the physical layer ranging window; and (iii) determining at least one metric associated with the ranging response for use in connection with upstream communications between the ONT and the OLT. The metric(s), used in connection with upstream communications, are accurately determined, and communications faults during normal operations are thus reduced.

Abstract: A method of densifying a bulk particulate material to provide a densified flowable bulk particulate material includes mechanically agitating the bulk particulate material in the presence of a densification agent thereby to provide a flowable bulk particulate material of increased bulk density.

Abstract: A methods and apparatus for providing an OLE automation interface to transactions services is provided. The method and apparatus includes an OLE/TP gateway. The OLE/TP gateway dynamically creates OLE objects that correspond to one or more transaction services. Client programs manipulate the methods and properties included in the OLE objects to perform transactions involving the transaction services. The present invention also includes a visual development environment that allows the user to visually select the type of OLE objects that the OLE/TP gateway makes available to client programs.

Abstract: A method of densifying a bulk particulate material includes at least partially confining the bulk particulate material, and rotating a rotatable member submerged under the bulk particulate material about an axis of rotation to cause movement of the material particles essentially towards or away from the axis or rotation, thereby to provide a densified bulk particulate material. The method is particularly suitable for densifying silica fume. The invention extends to apparatus for densifying a bulk particulate material.
