Abstract
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.
