Another area where composite gratings have made significant contributions is in spectroscopy. The ability to resolve complex spectra accurately is paramount in chemical analysis, environmental monitoring, and medical diagnostics. Composite gratings can be engineered to provide higher spectral resolution and sensitivity, enabling scientists to detect even trace amounts of substances. This capability is invaluable for applications such as gas analysis, where identifying specific gases is critical for environmental monitoring and safety.
One of the most common and effective purification technologies is the installation of reverse osmosis (RO) systems. RO systems use a semipermeable membrane to remove contaminants from water. The process involves pushing water through the membrane, which separates impurities from clean water. This method is particularly effective against dissolved solids, heavy metals, and even some bacteria and viruses, making it a popular choice for households with well water.
