A flexible bag for the preparation of an adipose tissue graft provided with a proximal end and a distal end and comprising: a front wall and a rear wall, which are connected to one another to define a receiving space on the inside; a first filter arranged inside the bag to divide the receiving space into a first chamber and a second chamber and to micro-fragment the adipose tissue to obtain a micro-fragmented adipose tissue; and a second filter arranged inside the second chamber to obtain a third chamber and to obtain the graft by separating a waste material from the micro-fragmented adipose tissue. The first filter comprises a distal edge which is connected to the front wall between the proximal end and the distal end and the second filter comprises a proximal edge which is connected to the rear wall between the proximal end and the distal end.

A fuel filter monitoring method includes receiving pressure signals that are indicative of a pressure drop across at least one fuel filter of a fuel supply system configured to supply fuel to at least one fuel injector of an internal combustion engine and receiving a condition signal indicative of a condition of a fuel supply system, the condition signal being generated by one or more of a geographic location sensor, an altitude sensor, and/or a fuel temperature sensor. The method includes estimating a remaining life of at least one fuel filter of the fuel supply system based on the pressure signal and the condition signal and outputting a notification indicative of the estimated remaining life.

A septic tank filter system includes a tank. The tank includes an inlet and an outlet, wherein the outlet is disposed on the tank below the inlet to enable a flow of wastewater to be gravity fed from the inlet to the outlet. A filter is positioned in the tank. The filter includes a frame. A filter media is disposed on the frame. The filter media is operable to filter the wastewater of waste material as the wastewater passes therethrough. A top opening is disposed on a top portion of the frame. A bottom of the top opening is located above the tank outlet and below the tank inlet. When the filter media is not clogged, a level of the wastewater remains below the top opening. When the filter media is clogged, the level of the wastewater rises until the wastewater flows over the top opening.

A fluid management system including an inlet configured to receive pre-processed fluid is provided. The system includes a filtering apparatus configured to remove contaminants from the pre-processed fluid. The filtering apparatus includes a plate having a first opening. A first manifold pipe is disposed on the plate and includes one or more perforations and a second opening at least partially aligned with the first opening. A second manifold pipe is disposed on the plate and includes one or more perforations. Filter media is disposed between the first manifold pipe and the second manifold pipe and is configured to separate the contaminants from the pre-processed fluid. The system also includes an outlet coupled to the second manifold pipe to receive processed fluid from the filtering apparatus.

A filter medium for removing contaminants from water includes a matrix including a plurality of fibers having an electrostatic charge such that the matrix is configured to remove contaminants from water by electrostatic attraction. The filter medium further includes a filler material including a ceramic substrate containing a mineral. The filler material is embedded in the matrix. When water flows through the filter medium, the mineral at least partially dissolves in the water such that a cavity is formed in the matrix in a location of the at least partially dissolved mineral.
