Title: Modular filtration system having removable filter element

Abstract: A filtration system that is coupled to a fluid flow for creating a uniform horizontal fluid flow through the filtration system to remove impurities from the fluid flow. The filtration system includes a filter having an inlet region, an outlet region, and a filter housing fluidly coupled between the inlet region and the outlet region. The inlet region includes an inlet pipe and a mixing chamber for creating a uniform horizontal fluid flow through the filter. The filter housing includes a removable filter element that receives the uniform horizontal fluid flow and removes impurities from flow, and the outlet region discharges the flow from the filter. In one embodiment, the inlet pipe includes a planar discharge end that is angled with respect to the horizontal axis of the fluid, and the mixing chamber includes a closed end, which the fluid flow strikes as it exits the inlet pipe to create a uniform horizontal flow through the mixing chamber. Additional filters can be joined in-series to form a modular filtration system, with each individual filter including a filter element that removes a predetermined impurity from the fluid flow.
