DETAILED DESCRIPTION

[0035] The aspects and advantages of the exemplary embodiments will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the disclosed embodiments, for which reference should be made to the appended claims. Additional aspects and advantages of the disclosed embodiments will be set forth in the description that follows, and in part will be obvious from the description, or may be learned by practice of the disclosed embodiments. Moreover, the aspects and advantages of the disclosed embodiments may be realized and obtained by means of the instrumentalities and combinations particularly pointed out in the appended claims.

[0036] FIG. 1a shows a front facing isometric view of the water filter buoy assembly 10, and FIG. 1b shows a rear facing isometric view of the water filter buoy assembly 10. The water filter buoy assembly 10 may include a float 100, a frame 101 for holding a filter (201, FIG. 2a) and at least one arm 105 connecting the float 100 to the frame 101.

[0037] The float 100 is generally constructed to have a buoyant force greater than its weight, may be composed of any material suitable for immersion in wastewater, and may be configured to ensure the water filter buoy assembly 10 remains afloat and upright. The float 100 may have a shape of a right circular cylinder and may vary in diameter and height, depending on the filter 201 size and weight. The float may optionally include a handle 106, allowing for placement of the water filter buoy assembly 10 in water or for removal or transport. The handle 106 may vary in length.

[0038] The frame 101 may include rails 103, 104 and a slot 109 for receiving the filter 201. The rails 103, 104 may oppose each other and may extend perpendicular to the slot 109 along a length of the filter 201, and may vary in length corresponding with the filter length. The rails 103, 104 may assist with filter insertion in addition to providing mechanical protection for the filter 201. The rails may be removably coupled to the frame 101, for example, using snap fit connectors 112, 113, or any suitable fastening mechanism or method. In some embodiments, the rails may vary from 10-500 mm in length. The slot 109 may be generally rectangular and may be oriented in a first plane at an angle to a base of the float, for example, less than 90 degrees. In some embodiments, the slot may vary from 100-300 mm in length and from 2-10 mm in height. The frame 101 may further include a bottom member 108 which may provide a support for resting approximately level on a flat surface. The frame 101 may also include a detachable nozzle adapter 107 with an inlet 110 that interfaces with a filter nozzle and an outlet 111. The nozzle adapter 107 may be removably attached to the frame snap using any suitable connector, for example, one or more snap fit connectors 114.

[0039] The at least one arm 105 may connect the float 100 to the frame 101. A length of the at least arm 105 may vary depending on a predetermined depth of the frame. In some embodiments, the frame may be oriented in a second plane different from the first plane. The at least one arm 105 may be coupled to the frame 101 with a mechanism 115 that orients the frame in one or more second planes different from the first plane causing the filter to tip in two different planes. The mechanism may include, for example, snap-fit connectors. Depending on the application, the at least one arm may attach to the frame at adjustable angles from 0 to 90 degrees to ensure that when submerged, an end of the filter 201 opposite the slot 109 is lower than an end of the filter in the slot 109.

[0040] FIG. 2a shows an exemplary filter 201 for use with the disclosed embodiments. The disclosed embodiments may utilize commercially available filters formed in the shape of rectangular plates and having a filter-active outer side and an internal discharge channel for filtered water. The rectangular plates may form an internal collection space attached to a perimeter endcap 203. The endcap 203 may have at least one filter nozzle 202 such that wastewater enters the internal collection space through the rectangular plates and exits through the filter nozzle 202, thus ensuring that filtered water is securely transferred from the filter to an external point of use.

[0041] FIG. 2b shows the exemplary filter submerged in wastewater and actively filtering out suspended solids as the wastewater travels in through the rectangular plate and out the at least one liquid tight outlet 202. This view is provided to better convey the operation of the filter itself. Within the filter, permeate passes to the interior collection space and to the endcap 203. From the endcap 203, permeate passes through the at least one filter nozzle 202, into the water filter buoy assembly nozzle adapter 107 via the nozzle adapter inlet 110, and out through the nozzle adapter outlet 111 for additional treatment or discharge. Dimensions of the filter 201 may vary in length, width, and height. Various filter technologies may include a variety of pore sizes, including micro, ultra, and nanofiltration.

[0042] An exemplary filter installation may include sliding the filter 201 along rails 103, 104 into slot 109, removing the water filter buoy assembly nozzle adapter 107 from the frame and affixing the nozzle adapter 107 to the filter nozzle 202, ensuring a leak-proof fit.

[0043] FIGS. 3a, 3b, 4a, 4b, 5a, and 5b show alternate views and configurations of the disclosed embodiments.

[0044] Various modifications and adaptations may become apparent to those skilled in the relevant arts in view of the foregoing description, when read in conjunction with the accompanying drawings. However, all such and similar modifications of the teachings of the disclosed embodiments will still fall within the scope of the disclosed embodiments.

[0045] Various features of the different embodiments described herein are interchangeable, one with the other. The various described features, as well as any known equivalents can be mixed and matched to construct additional embodiments and techniques in accordance with the principles of this disclosure.

[0046] Furthermore, some of the features of the exemplary embodiments could be used to advantage without the corresponding use of other features. As such, the foregoing description should be considered as merely illustrative of the principles of the disclosed embodiments and not in limitation thereof.
