Of the many water sources, such as water from rivers, springs, and also lakes, nothing is greater than sea water. More than 90% of the earth's surface is the ocean, which is a good alternative source of water for industries and settlements, as long as the water with high salt content can be treated properly.
Along with the development of the times, humans have found technology to treat sea water in various ways. So far, the usual technology for treating seawater includes distillation, ion exchange and arguably the most effective technology, namely seawater filtration or the Reverse Osmosis system.
Distillation is a technique of seawater evaporation. The water vapor from the evaporation results is then accommodated and used for daily needs. In a way, this technique is the oldest seawater treatment technique.
Ion exchange water treatment is a technology known from 1852. The concept is to exchange ions so that they can chemically separate seawater from salt using materials such as synthetic resins (cations and anions).
In addition to the two types of technology above, we from Indowater offer services to conduct seawater treatment using a technology called Sea Water Reverse Osmosis or SWRO. The biggest advantage of this technology is its ability to produce the purest clean water. Here is a further explanation of SWRO:
• SWRO technology is based on the concept of membrane technology to separate seawater from unwanted microorganisms and other particles.
• Reverse Osmosis is a process in which a solution with high concentration (sea water), is forced to go to a lower concentration solution through a semi-permeable membrane, through high pressure.
• The result of this technique is the filtering of molecules heavier than sea water, such as salt, microorganisms, and other substances, leaving clear and pure water that can penetrate the membrane.
SWRO systems are relatively new techniques and require a high initial investment. But the result is large amounts of sea water that can be processed into clean water for all industrial and household needs.
