Water is one of the primary needs for life, so a water crisis raises major cause for concern. Water shortage can and have occurred in many places throughout history, and one of the most recent examples is the dry spell that has been burdening California for more than three years now, with no end still in sight. This is not the worst drought experienced by the state, as experts say that the area has gone through dry spells that lasted 10 to 20 years in the past. However, that doesn’t make the current situation any less worrisome.
The Office of Governor Edmund G. Brown, Jr. reports about the measures the state is taking to help combat the water shortage, including putting up more legislations against water wastage. Governor Brown has also been discussing with experts about water conservation efforts.
Sources of Drinking Water
Conservation is not the only angle Californians are looking at to solve the water problem. Experts are also looking into various means of increasing the water supply. 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.
CBS reports how 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.
Reverse Osmosis Systems
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, like AXEON Water Technologies, provide systems designed for use in residential, light commercial, and commercial purposes, in addition to industrial-level systems.
