Columns for the treatment of a liquid with particulate material are disclosed comprising first and second layers of sheet material in face-to-face contact with each other, an inlet and an outlet located at points between the layers, and welds or the like for joining the layers together along a pair of substantially parallel paths between the inlet and the outlet in order to form an elongated space adapted to be filled with particulate material therebetween. In a preferred embodiment, the aforesaid column comprises a first column portion, and the column includes a second column portion which also includes layers of sheet material in face-to-face contact with each other, an inlet, an outlet, welds for joining the two layers of sheet material together along a pair of substantially parallel paths between the inlet and the outlet so as to form an elongated space adapted to be filled with the particulate material therebetween, and a tubular connector for connecting the outlet from the first column portion with the inlet to the second column portion so that liquid may be fed from the inlet to the first column portion through both column portions to the outlet from the second column portion for contact with the particulate material in both column portions.
A column for treating a liquid with particulate material which comprises first and second layers of sheet material in face-to-face contact with each other, an inlet located at a first point between said first and second layers of sheet material, an outlet located at a second point between said first and second layers of sheet material, joining means for joining said first and second layers of sheet material together in a substantially flat plane and along a pair of substantially parallel paths between said inlet and said outlet so as to form a substantially planar elongated space therebetween, and particulate material contained within said elongated space whereby said liquid may be fed from said inlet to said outlet for contact with said particulate material therebetween.
