Potassium iodide - Wikipedia
Potassium iodide is a chemical compound, mediion, and dietary supplement. As a mediion it is used to treat hyperthyroidism, in radiation emergencies, and to protect the thyroid gland when certain types of radiopharmaceuticals are used. In the developing world it is also used to treat skin sporotrichosis and phycomycosis.
TNT - Wikipedia
Pink water and red water are two distinct types of wastewater associated with trinitrotoluene (TNT).   Pink water is produced from equipment washing processes after munitions filling or demilitarization operations, and as such is generally saturated with the maximum amount of TNT that will dissolve in water (about 150 ppm.)
ISO 15512 - European Standards Online Store
The evaporated water reacts with calcium hydride to molecular hydrogen and calcium hydroxide. The hydrogen causes an increase of pressure in the vacuum that is proportional to the evaporated water. Volatile components, that do not react with calcium hydride condensate in a cooling trap and do not affect the measurement.
Treatment of wastewater from paper and pulp industry
Approximately 2-18 m3 of water (depending on the effluent management system used and whether water is recovered) and between 2 and 2.5 tons of wood are required to produce one ton of paper. During the manufacturing process, water acts as a disintegration medium for the raw materials, a transport for fibers, and for paper formation.
Preparing Anhydrous Reagents and Equipment | Protocol
Chemical reactions that are moisture-sensitive must be carried out in an anhydrous, or water free, environment. Reagents and reactants can sometimes react with or absorb water from the atmosphere. If this happens, the chemical or physical properties of the reagents can change, and the desired reaction will not take place or lead to a poor yield.

Titanium dioxide - Essential Chemical Industry
Heating evaporates the water and decomposes any remaining sulfuric acid in the solid. After cooling, the product is ''milled'' to form crystals of the size needed. Crystals may also be coated with another substance, such as aluminium oxide or silica, to make the titanium dioxide mix more easily with liquids or to make the water-based paints made from it last longer.
Cooling Tower | Yokogawa Taiwan Corporation
The solubility of calcium carbonate (CaCO 3 found in cooling water) is an inverse function, with respect to temperature, causing calcium carbonate scaling to occur on the heat transfer surfaces. The accumulation of a CaCO 3 scale layer reduces the heat transfer capability, causing corrosion and creating hot spots, resulting in thermal stress.
