Receipts of hydrogen at cleaning of natural and sewer waters photocatalytic and electromembrane methods

1 - the housing; 2 - cylindrical cathode with a porous sintered titanium, which is both a filtering element; 3 - anode, which is made in the form of a spiral of platinum and placed on the outer surface of the cathode; 4 - initial water pipeline the entrance of which is located above of the cathode; 5 - conduit diversion alkaline solution; 6 - pipeline diversion of hydrogen; 7 - capacity of water container gate to collect the hydrogen.

Device for water purification from heavy metals to produce hydrogen.

Fields of application

• The assumed of the use of technology that is developed for application to ceramic filters and membranes for use in catalytic purification of polluted water and gas.
• It is supposed to use the technology developed to ensure effective wastewater treatment galvanic production of heavy metal ions to obtain hydrogen collected in a separate container and can be used as an alternative fuel in energy, particularly in local plants.

Brief description

• The process will application of nanosized pellicle dioxide titanium on ceramic materials that are at room temperature, using a series of industrial equipment for sol-gel synthesis.
• The technological process, which provides that when imposing direct electric current as a result of water electrolysis and allocation of alkali near-cathode space titanium membrane-cathode will formed hydroxides of heavy metals, for which the membrane showed higher selectivity than the same ions.
  Thus the membrane-cathode allocate hydrogen, which under pressure with alkaline filtrate passes through the membrane.

Expected properties

• Optimization technologies improve performance ceramic membranes with parallel obtaining hydrogen from adsorbed in the surface of titanium dioxide films of organic pollutants.
• The device will allow the separation of hydrogen and the filtrate while obtaining fuel and purified against metal ions water (alkaline solution). It can solve both environmental and energy problems: cleaning of the water from heavy metal ions to the regulation norms with produce hydrogen.

Advantages

• Coatings characterized by high wear resistance and corrosion resistance, titanium dioxide semiconductor in the rays of UV lamp will generate redox radicals that will allow to avoid the problems associated with the accumulation on the membrane surface organic toxicants and get along with their hydrogen.
• Porous metal tubular membranes are resistant to chemical, biological and thermal effects, has been easily regenerated, including by reverse flow of water or air.
  Is shown high efficiency of water purification from heavy metal ions with concomitant release of of hydrogen method electromembrane which is getting implemented with by titanium membrane-cathode.
