Waterlogged wood is a wooden object that has been submerged or partially submerged in water and has affected the original intended purpose or look of the object. Waterlogged wood objects can also include wood found within moist soil from archaeological sites, underwater archaeology, maritime debris, or damaged wood objects.
Wood flooring installers, for example, have to verify that the MC of the wood matches the relative humidity in the air of the building. If this step is skipped, a vast array of problems may present itself: cracking, cupping, crowning, buckling, sunken joints, and cracked finishes.
Brackish water reverse osmosis (BWRO) is the desalination of water with less salt than seawater, usually from river estuaries or saline wells. The process is substantially the same as SWRO, but requires lower pressures and less energy. [1] Up to 80% of the feed water input can be recovered as fresh water, depending on feed salinity.
Water damage describes various possible losses caused by water intruding where it will enable attack of a material or system by destructive processes such as rotting of wood, mold growth, bacteria growth, rusting of steel, swelling of composite woods, de-laminating of materials such as plywood, short-circuiting of electrical devices, etc.
The five common chemical agents that damage wood are: Light – Creates a chemical reaction within the cell walls of wood, leading to a change in color or texture; Acids – Cause wood to become brittle. Alkalies – Cause the fibers of the wood to separate and break down. Salts – Similar to alkalies, salts break down the fibers of wood.
The most common means for removing water hardness rely on ion-exchange resin or reverse osmosis. Other approaches include precipitation methods, such as fluidized bed pellet softening, [6] and sequestration by the addition of chelating agents. Distillation and reverse osmosis are the most widely used two non-chemical methods of water softening.
