The present invention relates to a multistage fiber filtering apparatus capable of selectively filtering depending on turbidity of raw water, in which a first filtration mode where the raw water passes through a fiber ball medium, a second filtration mode where the raw water passes through a fiber yarn medium, or a third filtration mode where the raw water passes through both of the fiber yarn medium and the fiber ball medium may be selectively operated.

There is disclosed a tool for filtering a lubricant to meet a target ISO cleanliness code. The tool includes a skid-mounted integrated filtration system having a pump that circulates a flow of lubricant from an inlet port, through a heater, through a series of specifically sized filters, and past a digital particle counter. The filtration system also includes a user interface and a programmable logic controller (PLC) configured to track outputs from the pump, the oil heater, and the particle counter to monitor a cleanliness of the circulating lubricant. The filtration system also includes a filtration operations server in communication with the PLC and configured to implement a tracking and monitoring software application enabling control of the filtration system from the system itself or remotely through one or more remote user terminals such as a smartphone, a laptop or tablet computer, and the like. Other embodiments are disclosed.
