Water is a necessity for life and industry. With the water shortage in California, people are looking for ways to get clean water. One of the solutions that shows promise is using reverse osmosis (RO). RO has been in use for desalinating seawater. It works by applying pressure on untreated water, pushing it through a fine membrane that allows water molecules to pass but not larger particles.
Recycling sewage water can be the norm as the state goes through the drought. The process involves putting waste water through a usual sewage treatment plant. The water then goes through a reverse osmosis system for treatment the second time. Any chemicals that escape both systems are broken down by another system that makes use of hydrogen peroxide and ultraviolet light. According to the report, this method has already been in use in Southern California.
The resulting water from these processes is safe to drink. In fact, it reportedly tastes even better than the normal supply in Southern California, which was known to have a funny taste because of its dissolved salt content. Water that has gone through the three-system process described above contains significantly lower salt levels.
Large industrial plants employing reverse osmosis already exist, with several more already in the works. However, the system is also available for use in homes, as well as in commercial establishments. Water treatment manufacturers provide systems designed for use in residential, light commercial, and commercial purposes, in addition to industrial-level systems.
