  • Patent number: 9334183
    Abstract: A process has been developed to selectively dissociate target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism. This process can be used for the remediation of water, particularly ballast water.

  • Patent number: 8663465
    Abstract: A filtration and dispensing system that is particularly suitable for underdeveloped parts of the world is provided for storing, filtering, and dispensing rainwater, surface water, or groundwater. The system includes a bank of ceramic filters, a water retention container for holding water to be dispensed by the system, and at least one header tank to which water supplied from the water retention container is fed. A pump is utilized to withdraw water from a lower portion of the water retention container and supplied to the header tank. The withdrawn water is distributed by way of piping from the header tank to individual ceramic filters in the bank of ceramic filters, and a collection tank receives filtered water discharged from the bank of ceramic filters. Trickle feed nozzles or other discharge elements are used to discharge the filtered water from the collection tank for use.

  • Publication number: 20140042062
    Abstract: There is described a fluid treatment system that is particularly well suited for treating ballast water on a shipping vessel. The present fluid treatment system is characterized by having two general modes of operation. A so-called ballasting mode and a so-called deballasting mode. In the ballasting mode, water is pumped from the sea or other body of water in which the shipping vessel is located to a ballast fluid inlet in the present fluid treatment system. Thereafter, it passes through the filter separation and radiation treatment sections in the fluid treatment zone of the fluid treatment system. Next, the fluid exits the fluid outlet of the fluid treatment system and it is pumped to one or more ballast tanks that are located on the shipping vessel. In the deballasting mode, water contained in the ballast tank(s) is pumped to a deballasting fluid inlet of the fluid treatment system after which it is treated in the radiation section only—i.e.

  • Patent number: 8647514
    Abstract: A standing wave in a water current, which is subject to purification, is swirled in the lower mass-exchange chamber in order to create negative pressure along the central axis, the atmosphere air intake and crating of two countercurrents interacting with each other, resulting in a standing wave and oxygenation of the water current. A cylindrical mixing chamber, which is divided into the upper mass-exchange chamber and the lower mass-exchange chamber by dividing walls with a coaxial orifice towards the air-supply pipe and peripheral bypass channel. In the lower mass-exchange chamber, water, which is subject to purification, is swirled and under the negative pressure in the center it intakes air from the air-supply pipe, creating hydrosol and reaction area of ion exchange due to forming of the standing acoustic wave. Part of the processed current is outlet into the volume through a permeable wall in the side surface of the upper mass-exchange chamber.
