A showerhead assembly including a filter cartridge assembly having a replaceable filter cartridge. The showerhead assembly includes a water-directing and filtering assembly having a body portion and a face portion removably affixed to the body portion. The filter cartridge assembly includes a split filter cartridge housing and filter cartridge. A first part of the filter cartridge housing is disposed in the body portion and a second part is disposed in the face portion. The filter cartridge includes a casing and spaced apart first and second end walls, an inlet connector extending axially from the first end wall, and an outlet connector extending axially from the second end wall and being offset from the filter cartridge central axis. The second end wall includes a first recess extending linearly between a peripheral edge of the second end wall and terminating at a termination position substantially aligned with the filter cartridge central axis.

The present disclosure relates to a method for labeling particles with magnetic particles and an apparatus for labeling particles with magnetic particles.

The present disclosure relates to a method for separation of solid particles from a waterbody. Preferably, the present disclosure relates to a method, wherein a combination of chemicals including coagulant(s) and flocculant(s) are employed for said separation of solid particles, wherein suitable examples of solid particles are living organisms and non-living matter, wherein living organisms include autotrophs such as phototrophs, which are either microscopic or macroscopic in nature (algae). The disclosure thus particularly relates to method of chemical coagulation and flocculation for separating solid particles, preferably either algae or bacteria or both from a waterbody. The present disclosure also provides for an alternate method, wherein the aforesaid method of coagulation and flocculation is combined with electro-coagulation and/or pH modulation strategies for separation of said solid particles in any sequence.

Methods and apparatuses for screening are provided. Embodiments include a screen basket apparatus for screening material, comprising a grid frame having a plurality of openings arranged in a lattice and a plurality of screening cartridge assemblies affixed to the grid frame to cover the respective openings of the grid frame. The screening cartridge assembly includes a case and a screen assembly fitted into the case, and may be affixed to a set of transversal member of the grid frame. The case may be formed of a single injection molded piece integrally formed by injection molding one of a polyurethane or a thermoset polymer. The screening elements together form a generally continuous screening surface across the exterior of the grid frame, which reduces blinding and is resistant to wear and tear.
