Abstract

The electrolytic water treatment with rotating radial electrodes consisting of electrolytic vessel (1), inlet of waste water (2), outlet of clean water (3), froth collector (4) located above the water level, and waste or sludge drain (5) at the bottom of the vessel. It consists of at least six electrodes (12 and 13) located in radial direction and rotating around the axis (7) in both clockwise and counter-clockwise directions. Electrodes (12 and 13) are connected to dc power supply (8) and control system (9). Electrodes (12 and 13) are held in insulating brackets (11).

Description

Eiectroiitic water treatment with rotating radial electrodes

Technical Field

The Eiectroiitic water treatment with rotating radial electrodes is a part of machinery or equipment utilized for preserving and protecting the environment from pollution.

Background Art

Presently utilized water cleaning facilities are working on the basic principles of mechanical filtration, biological aerobic and annaerobic cleaning chemical treatment, radiation, electrolisis, and dialisis in order to achieve acceptable water quality.

The most frequent methods used by water cleaning facilities are ionic exchange, catalysts, or clarifiers where air bubbles are utilized for the removal of pollutants.

For liquid filtration we may also utilize the dialysis principle. The system consists of a semi-permeable membrane which allow smaller particles to pass through. The membrane system is utilized to remove organic matters and salts from the liquid. An example includes the reverse osmosis system where the semi- permeable membrane can be utilized to remove organic matters from liquid. In this case, the required pressure is directly proportional to water salinity.

Furthermore, the eiectroiitic process is utilized to remove polutants from water where the waste material is bonded to the electrodes based on electrochemical reaction.

All above listed systems are having low effeciency, require high capital investment, or require a large volume of expensive chemicals. Disclosure of the Invention

The basis of the Eiectroiitic water treatment with rotating radial electrodes invention is the principle of rotating electrodes with high oxidation/reduction effect during the electrolictic process. The electrodes are situated in a radial direction to the center of rotation.

Eiectroiitic water treatment with rotating radial electrodes consists of an eiectroiitic vessel with inlet of polluted water and outlet of clean product water. The clarifyer, which is located on the top of the vessel is responsible for the removal of froth from the liquid. The drain line for removal of slug is located at the bottom of the vessel. Inside the vessel there are at least six electrodes located in a radial direction around the center of rotation. They can be rotated in both clockwise and counter-clockwise directions. The electrodes are held in place with special brackets which funtion as an insulator.

The advantage of this Eiectroiitic water treatment with rotating radial electrodes system is that the equipment is working on a combination of multiple effects; wide spectrum of electrolisis, oxidation/reduction ion exchange, rotation and clarifying effect, and electro-coaugulation sedimentation.

The Eiectroiitic water treatment with rotating radial electrodes is highly effective in cases when the water is highly contaminated with micro-organims, metals, salts, acids, alkalines, or in cases where biological and chemical cleaning is not practical.

Design Details

Figure 1 illustrates Eiectroiitic water treatment with rotating radial electrodes in a section indicating individual components. Figure 2 indicates electrode positioning in a rotating system. Electrodes can be rotated in both clockwise and counter-clockwise directions.

Example of Embodiments

The Eiectroiitic water treatment with rotating radial electrodes indicated in figure one consists of electrolitical vessel (1), the inlet pipe for polluted water (2), and outlet for clean product water (3). In the eiectroiitic vessel (1), there is a system of electrodes (6) which are located in radial direction toward the axis of rotation (7). The electrodes are connected to a water supply (8) and are rotated by an electric motor (10). The froth is collected in the collector item (4) and the waste or sludge is removed from the bottom of the vessel (5).

The electrodes' polarity and direction of rotation is indicated by figure 2.

Item 12 is indicating electrodes from the eight group of elements from the Periodic Table of Elements and item 13 is indicating electrodes from the third group of elements from the Periodic Table of Elements. The number of electrodes from the third group are always twice the number of elements taken from the eigth group.

Electrodes are installed in a radial direction compared to the center of rotation and are held in position by insulating brackets (11). The electrodes are connected to direct current source and can be rotated in both clockwise and counter-clockwise directions. Furthermore, depending on process the electrodes may also remain stationary.

Industrial Applicability

The Eiectroiitic water treatment with rotating radial electrodes can be utilized to clean waste water from utilities thermal plant, petro-chemical industry, or other industrial fields. It is also possible to utilize the system for removal of pollution from swimming pools or increase the quality of drinking water.
