Claim:
1. A bipolar cell for a reactor, the cell comprising end electrodes and at least one bipolar electrode therebetween, the or each bipolar electrode comprising a diamond sheet, the cell including a porous support structure between each end electrode and the adjacent diamond sheet and, where there is more than one diamond sheet, there being a porous support structure between the or each pair of adjacent diamond sheets, the support structures acting to contact and support the or each diamond sheet; the cell further comprising a cell body having a cylindrical bore to accommodate the at least one bipolar electrode, an array of holes forming an inlet to the cell body through which untreated effluent enters the cell and an array of holes forming an outlet from the cell body through which treated effluent exits the cell, the holes of inlet and outlet arrays of holes being substantially uniformly distributed across the full height of the cylindrical bore in the cell body in a direction perpendicular to the plane of the at least one bipolar electrode, the inlet and outlet being arranged such that effluent flow from the inlet to the outlet is evenly distributed and substantially parallel to the plane of the at least one bipolar electrode; wherein the porous support structure supports the or each diamond sheet at sufficient points to reduce the risk of a fracture in use; and wherein the porous support structure is configured to increase turbulence in the cell.
