A method and apparatus for rapidly installing or withdrawing a sealing liner into or out of a subsurface well bore or borehole. An eversion aid, such as an open-ended cylinder, is engaged with the liner, the eversion aid serving to push the liner down the borehole during installation, and to assist in proper liner extraction during its withdrawal from the borehole. Water is transferred between the liner interior and the borehole outside the liner to regulate the disposition of borehole water, and to aid in proper sealing functions of the liner and to promote proper liner extraction during withdrawal.

An adiabatic condenser or fluid cooler is provided. A condensing or fluid cooling coil is provided. An adiabatic pad is provided wherein water can be used to cool the ambient air before entering or impacting the condensing or fluid cooling coil. Controls are provided that can adjust or eliminate the amount of water flowing over the adiabatic pad. The adiabatic pad may also be physically moved to allow ambient air to directly impact the condensing or fluid cooling coil.

A brush assembly releases a fluid and / or liquid solution directly onto a surface, such as a coat of an animal during grooming, or onto inanimate surfaces such as vehicles. The brush assembly includes a molded brush having a plurality of apertures integrated therein for delivery of a fluid. At least one base plate with grooming implementations, such as bristles or a sponge, is interchangeably attached to the brush base. An ergonomical handle is provided having a palm conforming top and finger indentation sides constructed to form an internal cavity. The ergonomical handle is ambidextrous in nature for interchangeable left and right handedness. A center cylinder is located within said internal cavity of said ergonomical handle and includes a bladder which aligns with the mid portion of the brush base for fluid delivery controlled upstream by a flow regulator. An optional mixing chamber housing a water soluble compound containing active ingredients may be attached to the flow regulator to form a liquid solution. The fluid and / or liquid solution is delivered directly to the surface during grooming.

A selective removal of chlorine and phosphorus that are detrimental to subsequent hydrothermal hydrocatalytic conversion from the biomass feed prior to carrying out catalytic hydrogenation / hydrogenolysis / hydrodeoxygenation of the biomass in a manner that does not reduce the effectiveness of the hydrothermal hydrocatalytic treatment while minimizing the amount of water used in the process is provided.

A method of regenerating N-Methyl-D-glu-camine-functional resin that has been used for boron-removal uses a closed recirculating loop for treating the conjugate acid salt of the N-Methyl-D-glucamine functionality of the resin. The new method reduces rinse water demand and improves pH control in a water treatment system. The new method can be used to improve the performance of boron-selective resins in stand-alone systems or as a second stage in a reverse osmosis seawater desalination system. The regeneration method is useful in any application where weakly basic anion exchange resin in the conjugate acid salt form is to be regenerated (neutralized) by alkaline treatment. Possible end use applications are in drinking water processing, agricultural water treatment, sweetener production, waste water processing, mining hydrometallurgy, and condensate polishing.

A selective removal of metal and its anion species that are detrimental to subsequent hydrothermal hydrocatalytic conversion from the biomass feed in a continuous or semi-continuous manner prior to carrying out catalytic hydrogenation / hydrogenolysis / hydrodeoxygenation of the biomass that does not reduce the effectiveness of the hydrothermal hydrocatalytic treatment while minimizing the amount of water used in the process is provided.

An anti-siphon system for use with an irrigation system, such as lawn sprinkling system is disclosed. The system includes a backflow prevention valve with a bonnet- and poppet valve system with a conical spring that biases a lower poppet valve head, and engages the valve body. The use of the conical spring simplifies the mechanism, while providing reliable backflow prevention.
