Abstract: A gas flotation tank is provided that includes a series of adjacent chambers which impart a rotational current therein. Each chamber is separated from a skim oil trough by a skimming weir. Each chamber comprises an alternating fluid communication device between adjacent chambers allowing fluid communication between adjacent chambers in the form of a communication port in the dividing wall between adjacent chambers and a chamber outlet in conjunction with a perforated plate and the outlet is positioned in fluid communication with the final chamber. An optional coalescing media may be positioned in or proximate the communication port to absorb or coalesce contaminants as they pass therethrough.

Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening. The vessel receives the water containing the first gas and passes the water through a series of gasification chambers. Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.

Abstract: A vacuum dehydrator for processing an oil containing entrained contaminants such as water, air, and particulates comprises a tower enclosing upper and lower chambers. A random packing is contained in the upper chamber. The oil is preheated to a temperature above the boiling point of water and is introduced into the upper chamber for downward flow through the random packing into the lower chamber. Entrained air and water is retained as water vapor in the upper chamber, and particulates are retained in the random packing. Heated ambient air is introduced into the lower chamber for upward flow through the random packing into the upper chamber, and the upper chamber is cooled to condense the water vapor. Oil and condensed water are pumped respectively from the lower and upper chambers.

Abstract: A fluid treatment device and method is proposed for the treatment of a fluid that has components to be separated, such as tailings. The fluid treatment device in one embodiment comprises a motive pump connected to drive fluid to be treated along a conduit through a restriction forming a nozzle into a mixing chamber and thence to a discharge. A port, which may be controlled by a valve, admits gas into an initial portion of the mixing chamber. The motive pump, nozzle, gas port and mixing chamber together form a phase separator. Multiple phase separators may be connected together in series. The mixing chamber may have constant diameter and a length to diameter ratio of 20:1 or 60:1 or more. The conduit terminates in a discharge. The discharge may supply the treated fluid to a secondary separation device such as a flotation cell. Solids and liquids may be taken off the flotation cell for disposal, further processing or delivery into a sales line.

Abstract: A column of solvent containing foaming contaminants is provided. Gas is educted into the solvent in the column so as to generate foam in the column. The gas is educted into the column independently of the input flow of solvent into the solvent using a pumparound arrangement with the solvent. Foam generation continues so as to push the foam up in the column, wherein much of the solvent that is in the foam is allowed to drain back down into the column. The foam passes through concentrators which increase the residency time of the foam in the column to further dry the foam and to create larger bubbles. The drier foam is pushed out of the column and into a container. The foam is broken up into gas and the liquid foaming contaminants. The gas is recirculated for injection into the column even after foaming has stopped. The foaming contaminants are concentrated at the surface level of the solvent in the column. These contaminants are removed from the column. A liquid separator separates immiscible liquids, such as oil, from the solvent.

Abstract: An apparatus and method are disclosed for environmental applications such as waste water treatment, de-inking of recycled paper, chemical/biochemical waste clean-up, and mineral beneficiation, using a multi-stage flotation column. A series of draft tubes arranged axially and separated by baffles provides individual mixing stages in the flotation column and a special gas distributor generates fine gas bubbles. The draft tubes create repetitive loop flow of the feed fluid in each flotation stage. This provides uniform distribution of the gas bubbles throughout the column and significantly enhances mixing and contacts of the gas bubbles with the impurities to be removed.
