What is PVD coating?
Physical Vapor Deposition (PVD): This is the category of processes where the material surface coating is applied through the condensation of the vaporized alloy coating onto the material surface, in a physical process involving the movement of particles across physical material phase boundaries (from gas to solid). To put it simply, the surface coating alloy is first vaporized and then sprayed onto the surface of the base metal (typically within a vacuum). There are other variations and subsets of PVD, but this is the basic operative principle behind the concept. PVD is commonly used to apply thin coatings of titanium nitride (TiN) in order to harden metal cutting tools and greatly increase wear resistance of the tool.

How does surface water treatment work?
In order to meet the requirements of the Surface Water Treatment Rule, a water system must both remove and inactivate the pathogens in the water. This process begins with coagulation, which destabilizes the particles in the water. Then, during flocculation, the destabilized particles bump into each other and form larger and larger flocs. These large flocs are given adequate time to settle out of solution via gravity during sedimentation. Any remaining particles and pathogens will be removed during the filtration treatment process. Finally, the water is disinfected to inactivate any remaining pathogens prior to entering the water system’s distribution system.

History of Coagulation in Drinking Water Treatment. Coagulation has been an important process in high-rate filtration plants in the United States since the 1880s. Aluminum and iron salts have been used in the coagulation process since the beginning. These salts are still the most commonly used coagulants today.

Coagulation . Coagulation is defined as the water treatment process of increasing the tendency of small particles to attach to one another and to attach to surfaces such as the grains of a filter bed. Many surface water supplies contain particles that are too small to settle out of solution on their own.
How does contact time work in water treatment?
In order for systems to be sure that they are properly disinfecting the filtered water, the Surface Water Treatment Rule requires systems to provide enough contact time. Contact time (CT) is a function of the known disinfection concentration and the amount of time that the disinfectant is in contact with the water. Contact time is expressed in terms of mg/L-min. The EPA has published tables that show how much CT credit water systems will receive. In order to use these tables you use the concentration of chlorine, time, water temperature and pH.
