ABSTRACT:
A method of forming a fluid treatment apparatus including providing a first and second sheets each having upper, lower, and side surfaces. A plurality of drive rod passages is formed through the first sheet between the side surfaces and through the upper surface. An inside surface of each drive rod passage is continuous with the upper surface and provides a bearing surface for a drive rod. At least one fluid injection passage and at least one fluid drain passage are formed through the first sheet between the upper and lower surfaces between the drive rod passages. A drive rod is inserted into each drive rod passage. The drive rods are rotatably supported by the bearing surfaces and extend above the upper surface. A plurality of drive rod passages is formed through the second sheet between the side surfaces and through the lower surface. An inside surface of each drive rod passage is continuous with the lower surface of the second sheet and provides a bearing surface for a drive rod. At least one fluid injection passage and at least one fluid drain passage are formed through the second sheet between the upper and lower surfaces between the drive rod passages. A drive rod is inserted in each drive rod passage. The drive rods are rotatably supported by the bearing surfaces and extend below the lower surface. The second sheet is arranged over the first sheet, such that the drive rods of the first and second sheets face each other.
