One of the most critical stages of water treatment is disinfection. This step is vital for killing pathogenic microorganisms that can cause diseases. Common disinfection methods include chlorination, where chlorine or chlorine compounds are added to kill bacteria and viruses, and UV radiation, which uses ultraviolet light to destroy harmful pathogens. The effectiveness of these methods is crucial in ensuring that treated water meets health standards set by regulatory bodies.

2. Ease of Installation Unlike traditional handrails that often require complex fabrication and specialized labor, modular handrail systems can be quickly assembled using standard tools. This not only reduces installation time but also lowers labor costs, making it a more economical choice for builders and contractors.

Safety is a primary concern for any handrail system, and FRP excels in this area as well. The non-conductive properties of FRP make it an excellent choice for environments involving electrical hazards, such as power generation facilities or chemical plants. Additionally, FRP can be engineered to meet specific slip resistance requirements, ensuring that individuals can maintain their footing even in wet or slippery conditions. This feature makes FRP handrail systems suitable for both indoor and outdoor applications, significantly enhancing safety.

Oil seals for cars

synthetic rubber gasket.
The oil seal would seal one face against a rotating member and the other face to a stationary housing. It would prevent dirt from coming between the hub or shaft and the seal.
Viton (FKM/FPM) Oil Seals
The seal shown in Fig. 14.2 is a relatively simple design; most automotive seals are more complex. Dust lips are often used to keep outside contaminants away from the oil lip seals; such seals thus have undercuts that make demolding more difficult. Fluoroelastomer compounds used for such undercut shapes must have reasonably high elongation at break at molding temperatures to avoid tearing the part during demolding. The metal insert is often U-shaped, and stock may be molded to form a thin layer over the outside of the insert. Since both compression and injection molding methods are used, suppliers of fluoroelastomers for shaft-seal applications often must provide different versions of the same polymer composition-medium to high viscosity for compression molding, and low to medium viscosity for injection molding. Different precompounds may be necessary to accommodate relatively long compression-molding times at low temperature and very short injection-molding times at high temperature.
These types are made with a metal outer case and a PTFE lip. They are suitable for a wide range of temperatures from -90 °C to +260 °C.These lip seals can also be used for higher pressures of up to 10 bar (special types up to 25 bar) and rotational speeds of up to 40-45 m/s. Certain grades of PTFE are suitable for use in pharmaceutical and food applications. One important point is that PTFE lip seals do require a shaft with a harder, smoother finish.
