What are the new approaches to water treatment?

Jun 24, 2018


Along with the rapid development of science and technology, the pressure driven reverse osmosis membrane separation technology (RO) membrane, membrane module, equipment and process of innovation and improvement, there were large but also more and more people realize the limitation of RO technology exists in the field of energy saving, environmental protection, and to desalination

Speaking, RO technology can be considered to be near the peak of development.

Abroad, therefore, has carried out "forward osmosis membrane separation technology (FO)" of related research, and obtained certain achievements, in seawater desalination, sewage treatment, food processing, medicine and other fields has been used, especially the "pressure slow penetration (FRO) sea power", is a very promising clean renewable energy development technology J.

However, there is little concern about the separation technology of positive permeation membrane in China, and there are not many related researches and papers.

In the 1990s, though, China had the creative invention of "non-pressurized adsorption infiltration seawater desalination" (CN92110710.2).

The forward osmosis separation technique has been applied very early.

Long ago, salt was used to store food for long periods of time, because most bacteria, molds and pathogens were dehydrated or temporarily inactive due to osmosis in the high-salt environment.

Nowadays, people have started to study the water desalination, industrial wastewater treatment, and waste permeation solution using the positive permeation membrane separation technology.

The food industry USES the forward permeable membrane to concentrate the beverage in the laboratory.

The life support system of emergency rescue USES the forward permeable membrane separation technology to make fresh water.

With the development of material science, forward osmosis technology has been applied to the release of drug control in human body.
