Abstract: A filter sector assembly for a disc filter, which disc filter has a fiber suspension containing bath and a core assembly adapted to rotate on a horizontal axis. The filter sector assemblies are rotatably supported with relation to the bath on the core assembly. The filter sector assemblies are spaced along the core assembly and supported on the core assembly. Each filter sector assembly (50) has two adjacent filter sectors (10A; 10B) releasably fixed to a bent support plate (30). The two adjacent filter sectors (10A; 10B) are attached as a pair of filter sectors (10A; 10B) by fastening the support plate (30) to the core assembly (21; 21A, 21B) of the disc filter.

Abstract: A catch basin stormwater filtering apparatus includes a support frame and a filter medium supported by the support frame. The support frame includes a planar upper plate and a planar lower plate disposed below and in close proximity to the upper plate. The upper and lower plates have substantially the same outer dimensions, and the support frame defines a central opening. The filter medium is in the shape of a basket and includes lateral side walls of which adjacent walls are joined together, and a bottom wall, the lateral side walls defining a top opening which is disposed in alignment with the central opening of the support frame. The filter medium also includes a flange that extends outwardly from the lateral side walls at the top opening of the filter medium. The flange is interposed between and adhesively joined to the upper plate and the lower plate of the support frame.

Abstract: A fabrication method for a filter containing tragacanthin-polyvinyl alcohol (PVA) nanofibers includes obtaining a homogenous tragacanthin-PVA solution by obtaining a PVA solution by dissolving PVA in distilled water, and adding tragacanthin to the PVA solution. The method may further include obtaining a support layer by coating a stainless steel mesh with a thin layer of a hydrophobic polymer, coating a stainless steel mesh with the thin layer of the hydrophobic polymer comprising electrospinning a hydrophobic polymer solution onto the stainless steel mesh, and forming a tragacanthin-PVA nanofibrous web on the support layer by electrospinning the homogenous tragacanthin-PVA solution onto the support layer.

Abstract: A filter for a sorbent regeneration process includes a base, a central rod, support frames, and a filter screen. The central rod is coupled to the base and defines a longitudinal axis of the filter. Each of the support frames are coupled to and protrude radially from the central rod. Each of the support frames are coupled to the base. For each pair of neighboring support frames, the filter includes a triangular support member disposed between the pair of neighboring support frames. Each triangular member is coupled to the central rod and to each of the neighboring support frames. The filter screen surrounds the support frames and is coupled to the support frames and to the base.
