  • Patent number: 5445729
    Abstract: A reverse osmosis (RO) unit uses a membrane permitting operation at abnormally low water pressures, typically as low as 10 PSI. Because any requirement for a pump to boost inlet water pressure is obviated, the RO unit makes do with only one, small and compact, outlet pump. An optional single, or a dual-channel dual-pass, ultraviolet (UV) light source sterilizes filtered inlet, and/or the purified output, water flows. Purified water is stored at atmospheric pressure in a simple storage bag, and is dispensed on demand by force of the outlet pump. The entire RO unit--storage bag, pump, filters, UV sterilizer, membrane and all--is preferably entirely integrally packaged in a compact and aesthetically pleasing cylindrically-shaped housing. The RO unit so housed is suitably deployed on a household counter top while flow-connected to normal household plumbing--typically to the faucet and drain of a kitchen sink--and while electrically connected to normal household power.

  • Patent number: 5433842
    Abstract: A marine vessel waste treatment system includes a tank for receiving successive charges of liquid and solid waste material. A water conduit conducts heated water from the vessel's engine through the tank to heat the contents thereof above the level at which coliform bacteria can survive, thereby reducing the count of such bacteria to a level at which it is safe and acceptable to discharge the material into a waterway. A macerator pump is mounted in the tank for operation only after the temperature within the tank is sufficiently high. An electrically operated heating element is also mounted in the tank to accelerate the treatment of waste and can be used alone when desired. A thermal switch at the waste material input inhibits discharge if a fresh charge of material is received when the system is ready to discharge, thereby preventing discharge into the environment of untreated material.

    Abstract: An oil and water separator for separating oil from water collected in a bilge of a boat prior to discharging the water overboard. A reservoir is provided for receiving the mixture of oil and water from the bilge. The oil separates from the water and floats on top of the water. When only water is positioned between a pair of spaced electrical probes carried in the reservoir, such causes a drain valve to be opened to drain the water from the reservoir. As the water is drained from the reservoir, the oil floating on top of the water will come between the probes and close the valve, stopping the draining of water from the bottom of the reservoir. A mixture of oil and water is pumped from a tank carried in the bilge at an intermittent rate so that the mixture is allowed sufficient time to separate in the reservoir.

    Abstract: A separator for removing oil-like substances from water using vertical columns of coalescing media to then enhance separation of the two phases. The coalescing media is an inert packing material having surfaces to enhance coalescing without significant resistance to flow. Final oil removal is achieved by a vertical column of charcoal pellets. The separator is of particular value in the processing of oil/water discharges from air compressing systems. This produces water that can be discharged in an environmentally safe manner to conventional sewers, etc. The oil is held in a convenient storage vessel for ultimate disposal. No pumping devices are needed in the separator as flow is provided either by the pressure in the outlet from the compressor system, or by gravity from a feed tank. The vertical columns are arranged within a cylindrical vessel to minimize floor space and plumbing. The oil concentration in the product water is below current EPA standards.

  • Patent number: 4933524
    Abstract: A clarifier basin is provided with upflow channels for removing solids from liquid that flows up the channels. The channels are defined by pairs of spaced sheets. Each sheet is provided with three-dimensional (3D) members, such as spherical bubbles or ellipsoids, that are in a two-dimensional array or regular pattern. The sheets are positioned closely adjacent to each other so that the 3D members on one sheet nest with the 3D members of the adjacent sheet to form interstices that collect the solids. The sheets are movable to enlarge the interstices so that air bubbles can flow up a selected channel and remove the solids for collection by a reservoir located above the selected channel. An air supply and the reservoir traverse the channels to remove the solids from the channels on a one-by-one basis.

  • Patent number: 4909948
    Abstract: A method and apparatus for disposing of waste water above ground is disclosed. Effluent is deposited in a first tank wherein solids are broken down and liquified by a primary preconditioning unit. The preconditioned effluent is transferred to a second tank. A secondary conditioning unit in the second tank suspends liquid and solid particles in the tank air and vapor, vaporizes the suspended liquid and any entrained solid particulate material, and then discharges the vaporized material into the ambient atmosphere. An automatic control means senses vapor temperature and operates a stack damper and vacuum means which causes the vapor stream, thus preventing escape of non heat-treated vaporized materials. Another automatic control means activate the secondary treatment unit heater only when the liquid level of the second tank is within a preselected range.
