The or each bipolar electrode comprises a diamond sheet. The cell includes a porous support structure, for example in the form of spacers, a lattice of plastic rods, or a woven mesh, between each end electrode and the adjacent diamond sheet, there being porous support structure between the or each pair of adjacent diamond sheets, the support structures acting to contact or support the or each diamond sheet.
Abstract:
An electrocoagulation reactor for the treatment of wastewater. The electrocoagulation reactor typically engages a DC power source and a source of wastewater to be treated. It has a housing with walls and a wastewater inlet, and a treated wastewater outlet. There is at least one anode/cathode pair of oppositely charged spaced apart plates that engage the power source to charge the anode with a positive charge and the cathode with a negative charge. Between each anode/cathode pair is at least one segmented intermediate plate, which is not engaged to the power source of electrical energy, and which intermediate plate is segmented into multiple segments, which multiple segments lay generally in the same plane.
Abstract:
A water purification apparatus is provided. The apparatus includes a casing and an electrode array. The casing has an outer surface, a substantially annular inner surface, and a water flow passage chamber surrounded by the substantially annular inner surface, the water flow passage chamber providing an outer annulus region and an inner central region. The electrode array features at least four electrodes in adjacent relationship to one another and circumferentially spaced apart from another about the outer annulus region, each electrode having a respective first planar surface and a respective second planar surface facing and substantially parallel to the respective second planar surface and the respective first planar surface of the adjacent electrodes on opposite sides thereof.
Abstract:
An electrolysis device is configured such that water flowing into a container from an inlet flows from an upstream side to a downstream side in the container and flows out from an outlet. A first electrode pair is arranged on the upstream side than a second electrode pair. In the electrolysis device, in order to suppress a decrease in current density due to electrolyte concentration in the water in the second electrode pair arranged on the downstream side than the first electrode pair, the current density in the second electrode pair is adjusted.
Abstract:
The invention relates to an electrolysis device for cleaning acidic waters which comprises a cathode, an anode, and an ion exchange membrane, wherein the membrane is arranged between the cathode and the anode and is attached at least along the entire circumference of its rim, wherein many inlets and outlets are arranged along the upper and lower rim of the electrolysis device which are linked to the cathode space or to the anode space, in such a way that a plug flow, ideally with a laminar profile, is created in the cathode space and in the anode space.

Abstract:
An apparatus for electrochemical treatment of contaminated water or wastewater comprises a container or tank having an inlet and an outlet and a feed pump for the water to be treated, connected to the inlet for supplying the water through the inlet to the container or tank. Parallel pairs of electrode plates are situated in vertical position in the container or tank and form parallel vertical passages therebetween for the water to be treated. In the pairs of electrode plate at least one electrode plate comprises holes connected to a feed pump for an auxiliary medium. Said pairs of electrode plates are positioned between the inlet and outlet in the container or tank such that in at least part of the flow route between the inlet and outlet the water passes upwards in the vertical passages. The feed pump for the water to be treated and/or the feed pump for the auxiliary medium is a pulsating feed pump.
Abstract:
Process and apparatus to remove colloids and nitrogen compounds from contaminated water by coagulating the colloids and separating them from the water. The water is then continuously oxidized with chlorine electrolytically to destroy the nitrogen compounds.
Abstract:
Disclosed is an ionization water treatment apparatus using a carbon nanotube. In the ionization water treatment apparatus, water flowing through the tubular body is ionized and activated due to the potential difference, and a filter is constructed in such a manner that the water makes contact with the carbon nanotube to perform an antibacterial function and a function of adsorbing heavy metal, so that the structure thereof is simplified, a superior antibacterial effect and superior ionization performance are represented, and rust is prevented in a tubular body due to the removal of foreign matters. The filtering member is constructed in such a manner that the contact area between the water passing through the tubular body and a filter is maximized, so that efficiency is more increased in an antibacterial function and in the removal of foreign matters when water passes through a filtering member.
