    摘要: A fluid treatment element is adapted for cross flow filtration which includes a fluid treatment pack having first and second lengthwise ends, a fluid treatment layer that may be pleated, a first mesh layer disposed on a first side of the fluid treatment layer and a second mesh layer disposed on the second side of the treatment layer, the element defining a flow path for a process fluid to be treated passing in a lengthwise direction of the fluid treatment element inside the first mesh layer and a flow path for permeate passing through the second mesh layer. The first mesh layer may open onto the first lengthwise end with the second mesh layer including sealant at the first lengthwise end such that fluid can flow through the first lengthwise end into the first mesh layer but not into the second mesh layer. The element may include a core having a blind region in which fluid cannot pass therethrough and at least one regions where fluid can pass through the core.

    摘要: The present invention provides a filter sealing device for a filter element. The filter element includes an end portion defining an opening. The sealing device includes a body having a first section attached to a second section. The first section is positionable within the opening in the filter element with the second section facing an open end portion of the filter element. The first section has a larger coefficient of thermal expansion than the end portion of the filter element so that an increase in temperature results in the first section of the body expanding at a greater rate than the end portion of the filter element. These differing rates of expansion cause a compressive force to be exerted between the first section of the body and the end portion of the filter element.
