[0004] Figure 2 illustrates a device for channeling pressurized water through an AdBlue filter in one embodiment of the invention.

Detailed description of the embodiments
[0005] Figure 1 illustrates a method 100 for backflushing a filter. The method 100 comprises connecting 110 a water sump to a water pump and connecting 120 the water pump to a pressure regulator. The method 100 further comprises connecting 130 the pressure regulator to a dosing module filter positioned within a dosing module tank, channeling 140 water from the water sump to a water pump, channeling 150 pressurized water from the water pump and delivering pressurized water to the pressure regulator, and channeling 160 pressurized water from the pressure regulator to a water filter, wherein the pressurized water is channeled from a lower portion of the water filter to an upper portion of the water filter through the water filter to dislodge dirt particles out of the water filter.

[0006] Figure 2 illustrates a device 200 for channeling pressurized water through a water filter 240. The device 200 comprises a water sump 210, a water pump 220 in flow communication with the water sump 210, and a pressure regulator 230 in flow communication with the water pump 220, the pressure regulator 230 adapted to supply water under pressure from a downstream portion of the water filter 240 to an upstream portion of the water filter 240 through the water filter 240 to dislodge dirt particles out of the water filter 240.

[0007] Figure 1 illustrates a method 100 for backflushing a filter. The method 100 comprises connecting 110 a water sump to a water pump by mean of a pipe. Therein, water from the water sump is supplied to the water pump via the pipe. Therein, the water pump is connected 120 to the pressure regulator by means of a pipe. Therein, water from the water pump is supplied to the pressure regulator via the pipe. The method further comprises connecting 130 the pressure regulator to a dosing module filter that is positioned within a dosing module tank. Once the pressure regulator is connected to the dosing module filter, the water is channeled 140 from the water sump to a water pump. Therein, the pressurized water is channeled 150 from the water pump and delivered to the pressure regulator. From the pressure regulator, the pressurized water is channeled 160 to a water filter. More specifically, once the pressurized water is channeled to the water filter, the pressurized water is channeled from a lower portion of the water filter to an upper portion of the water filter through the water filter to dislodge dirt particles out of the water filter. Therefore, the water filter that has dirt particles dislodged from it is now cleaned and may be reused in the subsequent cycle.

[0008] In a further exemplary embodiment, a device 200 for channeling pressurized water through a water filter 240 is described. The device 200 comprises a water sump 210 and a water pump 220 in flow communication with the water sump 210 and pressurizes water that flows from the water sump 210. A pressure regulator 230 is in flow communication with the water pump 220 and receives pressurized water that is delivered from the water pump 210. In an exemplary embodiment, the pressure regulator 230 is adapted to supply water under pressure from a downstream portion of the water filter 240 to an upstream portion of the water filter 240. More specifically, the pressure regulator 230 is adapted to supply water under pressure from the underside of the water filter 240 through the water filter 240 towards the top portion of the water filter 240. As the water under pressure flows through the water filter 240 towards the top portion of the water filter 240, the water under pressure dislodges dirt particles out of the water filter 240, thereby cleaning the water filter 240. The water filter 240 is thereby cleaned and ready for operation in the subsequent cycle.

[0009] It must be understood that the embodiments explained above are only illustrative and do not limit the scope of the disclosure. Many modifications in the embodiments with regard to dimensions of various components are envisaged and form a part of this invention. The scope of the invention is only limited by the scope of the claims.
