Abstract: A total water desalination system is disclosed that includes a centrifugal separator, a feed-water device controlled by a relative humidity sensor, an air pump, an evaporator core, an air dryer, a non-particulate coalescent air filter, and an air flow/brine gravity separating tank. The evaporator core typically contains multiple conical processing chambers and introduces a physical dynamic that increases the surface area of the water, using low-level thermal energy to vaporize micron-size water particles into a gaseous state, suitable for reconstitution into desalinated (or lower salt content) water. The evaporator core operation principles are based on creating a highly dynamic environment that separates impurities from sea, brackish, river, or turbid water; evaporating the water into a residual clean vapor, and returning the vapor to water composition with high efficiency.

Abstract: Method and apparatus for treating air containing hydrogen sulfide gas, volatile organic compounds, heavy metals and other mercaptans in order to reduce odor and corrosion related to wet wells, dry pits, grease traps and the like. The system comprises a first and second stage air treatment system. A vacuum pump in the primary (stage 2) treatment housing vacuums the contaminated air from the source and pumps the air through a set of diffusers into a treatment fluid wherein the air is then passed through a pair of porous plates and upward through a discharge pump and then into the atmosphere. Prior to treating the air in the primary housing, it is treated in a pretreatment dry air filter wherein the air is inlet into the pretreatment (stage 1) housing and then through a microfilter prior to being passed into the primary housing for further treatment.

Abstract: A method and apparatus are provided for improving the efficiency of an aqueous froth filter. An array of saturated mesh assemblies interacts with an incoming contaminated air stream. As the air stream flows through the saturated mesh assemblies, an aqueous froth is generated immediately downstream of each mesh assembly. As the bubbles of the froth move downstream towards the next saturated mesh assembly, the velocity of the air stream causes at least some of the bubbles to burst. The bursting bubbles rupture into hundreds or thousands of micro-droplets. The micro-droplets are used together with the aqueous froth to coalesce with or otherwise bind with contaminants in the air stream. An optional feature is that massive particles greater than three microns in diameter are removed by inertial impaction, whereby those heavy particles collide with the walls of serpentine shaped vanes of a mist eliminator. The method and apparatus are capable of filtering chemical and biological warfare agents out of an air stream.

Abstract: Exhaust gases enter the tank of a columnar vessel (12) and are subsequently forced through a diffuser (24) that is at least partially immersed in a column of solution.

Abstract: The apparatus is a portable paint spray capture apparatus that limits dispersion of sprayed paint and permits spray painting small surfaces in unenclosed areas without harming the environment or nearby objects. An open top container is located below the surface being painted and hoses interconnect the container to a vacuum device drawing air from the container and through a water trap that collects paint particles. Air leaving the water trap passes through an underwater mesh screen to form smaller bubbles to help separate out the paint particles. Air movers push air from opposite sides of and toward the center of the surface being painted. Significant air flow paths are thereby established from the sides of the spray area into the container below it, and virtually all of the paint not adhering to the surface being painted is collected by the water trap.

Abstract: An apparatus is provided for separation of suspended solid particles from fluids, for separation and mixing of fluids, and for dissolving gases in aqueous fluids. The apparatus employs a grooved ring to divide the fluid stream and impart a high velocity on each of the divided or sub-streams. A grooved ring with any number of grooves that may be spiral in shape is used to create a high velocity circular motion on a divided stream for separation of suspended solid particles by centrifugal force in a cyclone filter and for saturation of liquid with gases in a fluid mixer where gases are introduced through a diffuser. A grooved ring with any number of grooves that may be radial is used in a fluid mixer to divide a stream of fluid, produce a high velocity flow through each groove, introduce a second fluid through an orifice into the first fluid flowing through each groove, and direct the fluid mixture to a center impact zone where the various streams collide to complete the mixing.

The device includes a valving system arranged to control flow of atmosphere into and out of the container, and includes a bubbler filled with treatment liquid, such as a disinfectant or purifying agent. Filtered air is bubbled through the treatment liquid prior to feeding the replacement atmosphere into the sealed container. In one embodiment, a floating valve assists in preventing undesired suction of the treatment liquid into the container. In another embodiment, the treatment device is attached to exhaust atmosphere to keep an ambient area clean as new liquid is added to the container and harmful atmosphere is exhausted. Methods related to the above are also defined and claimed.

Abstract: An aeration system for removing radon and other volatile compounds from a water or other liquid source. Water supplied from a well and/or water pressure/storage tank enters an aeration tank and is sprayed through a clog resistant nozzle. The nozzle creates a cone shaped spray of very fine water droplets or particles. Such spraying exposes the maximum amount of water surface area to the air stream and hence removes about 50% of the existing radon and other volatile compounds contained within the water. The sprayed water is then collected and fills the aeration tank and the collected water is then exposed to a source of high pressure, filtered air which is blown through a conventional sparger to vigorously agitate and aerate the sprayed and collected water in the aeration tank thereby removing any remaining radon and other volatile compounds from the water.
