Abstract:
A fluid purifying apparatus that purifies fluid containing organic matter has a reactor including a first transfer part that receives the fluid from outside and transfers the fluid in a vertical direction from an upper side to a lower side while heating and pressurizing the fluid and mixing the fluid with an oxidant, a second transfer part that receives the fluid that has passed through the first transfer part and transfers the fluid in the vertical direction from the lower side to the upper side, and a partition member that partitions an upper part of the reactor into the first transfer part and the second transfer part, and a solid storage part that communicates with the first transfer part and the second transfer part below the partition member and receives solid matter contained in the fluid that settles while the fluid is transferred.
Abstract:
The present invention comprises a process and apparatus for separation of hydrocarbons from hydrocarbon-containing produced water, wherein in stage 1 the hydrocarbon-containing produced water is supplied with a gas-containing component, whereupon a gas- and hydrocarbon-containing produced water mixture is fed to an inlet tube (22, 27) in the center of a tank, whereupon the said mixture is tangentially distributed via at least one nozzle (7) and at least one baffle plate (8.1), whereupon separated hydrocarbons are conveyed to at least one outlet from the tank and cleaned water is conveyed to an outlet (12) from the tank.

Abstract:
According to an aspect of the present invention, a hydrogen-containing water generating electrode includes a positive electrode that is a tubular conductor and includes a plurality of openings in a side portion, an insulator that is provided on an outer peripheral portion of the positive electrode and includes a plurality of openings, and a negative electrode that is a tubular conductor provided on an outer peripheral portion of the insulator and includes a plurality of openings in a side portion. The openings of the positive electrode and the openings of the negative electrode are larger than the openings of the insulator.
Abstract:
The present invention relates to the treatment of wastewater by electrochemical reactions. More particularly, an Electro-Reaction Unit (ERU) is disclosed. The ERU is provided with at least one electrolytic cell comprising a pair of self-cleaned electrodes for purifying wastewater. Along with electro-reactions, electrodes of the ERU are submitted to passivation, i.e. coverage with an oxide layer. The present invention provides a solution for alleviating passivation with a self-cleaning system comprising hard elements, confined in a cage and movable therein, for bombardment of the electrodes and rupture of the oxide layer. The present invention further provides a related process.
Abstract:
A portable solar-thermal device produces fresh water from sewage water or salt water. The device has a closed fluid circuit made of connected pipe or hose elements with a sewage water supply and a fresh water runoff. The fluid circuit has a tilted heating section essentially aligned normally to the sun irradiation for heating and vaporization of the sewage water. Connected to this is an essentially vertically aligned condensation section for condensation of the fresh water and heating of the sewage water. A storage section is designed as base area for the condensed fresh water. The heating section of the fluid circuit has a solar collector for concentration of the thermal energy of sun irradiation on a vaporization area inside the heating section.
Abstract:
A water treatment device generates a bubble in water to be treated inside a treatment tank, and treats the water to be treated through use of radicals that are generated by bubble electric discharge caused via the bubble. The water treatment device includes main electrodes for forming a main discharge area between a first main electrode and a second main electrode, auxiliary electrodes for forming a preliminary discharge area between a first auxiliary electrode and a second auxiliary electrode, and a bubble generator generating a bubble in water to be treated through use of an externally supplied gas. When a bubble generated by the bubble generator passes through the preliminary discharge area, discharge is caused via the bubble, and, when the bubble in an excited state subsequently passes through the main discharge area, the bubble causes discharge again to generate radicals.
Abstract:
Provided is a filter device for filtering liquid by passing it through one or more filtering media. The filter device comprises a cartridge defining a treatment region filled with said one or more filtering media and has a liquid inlet and a liquid outlet. A locking mechanism may be located within a liquid flow through the cartridge and configured to lock at least one of the liquid inlet and the liquid outlet upon expiration of life time of said at least one filtering medium.
Abstract:
A water purification system for continuously disinfecting water in a holding tank that provides uniform mixing and increased residence time. The system comprises a double disinfectant tank for potable water, comprising an inner tank and an outer tank. The inner tank being located wholly within and in the lower portion of the outer tank. The water and disinfectant inlet feeds water directly into the inner tank through a tube extending into the inner tank. The inner tank is sealed off from the outer tank except for limited openings located primarily in the lower half of the inner tank wall. The inlet tube preferably extends at least about 50% of the height of the inner tank, to a point above the location of the limited openings in the lower half of the inner tank. This results in better mixing, especially when the flow through the limited openings is high enough to create turbulent flow, and greater residence time compared to baffled tanks.
