Plate assembly and method of manufacturing for use in water treatment

A plate assembly for a plate settler, the plate assembly comprising:

• a plate body defining a first end and a second end, the plate body comprising a first surface and a second surface each extending between the first end and the second end, wherein the plate body defines a plate body thickness between the first surface and the second surface, wherein the plate body defines a first lateral edge and a second lateral edge each extending between the first end and the second end;
• a first support plate attached to the plate body on a first axis extending between the first end and the second end, wherein the first support plate is configured to support the plate body along at least a direction of the first axis, wherein the first support plate defines a first support plate thickness, wherein the first support plate thickness is greater than the plate body thickness;
• and
• a central stiffener attached to the plate body on a third axis extending between the first lateral edge and the second lateral edge, wherein the central stiffener is configured to support the plate body along at least a direction of the third axis, wherein the central stiffener defines a central stiffener thickness.

• a first support plate attached to the plate body on a first axis extending between the first end and the second end, wherein the first support plate is configured to support the plate body along at least a direction of the first axis, wherein the first support plate comprises:
• a first leg and a second leg defining a first intersection therebetween, wherein the first intersection is disposed on the first axis, wherein the first leg comprises an attachment surface configured to attach to the plate body, and wherein the first leg is angled relative to the second leg;
• and
• a third leg and a second intersection between the second leg and the third leg, wherein the third leg is angled relative to the second leg;
• and
• a second support plate that comprises:
• a first leg and a second leg defining a first intersection therebetween, wherein the first leg is angled relative to the second leg;
• and
• a third leg and a second intersection between the second leg and the third leg,
• wherein the third leg is angled relative to the second leg,
• wherein the first leg of the first support plate is positioned between the plate body and the third leg of the second support plate.
