Israel's drip irrigation water-saving technology has been widely used around the world. Its water technology has now made another breakthrough, using ultraviolet light to purify water and bacteria to treat organic sewage. Israel ’s next goal is to sell these technological products abroad.
Technological innovation
Aatlantium is an Israeli private technology company located outside of Jerusalem. The company's newly developed ultraviolet water purification technology mainly uses ultraviolet radiation to "inhibit" bacterial regeneration and infection in water to achieve the effect of purifying water quality.
This technology connects a giant quartz tube to the water pipe system, which can purify 200 cubic meters of water per hour. The company's marketing department manager Dana Kogan said that chlorine water purification may produce chemical by-products, and ultraviolet water purification can avoid this shortcoming; compared with heating water purification, ultraviolet water purification is cheaper.
Aqwise has made breakthroughs in the use of biological technology to treat wastewater. The company makes small plastic rings into "biological carriers", which carry a lot of natural bacteria on the surface. A water spray system drives the "biological carrier" to flow in the sewage, and the bacteria are responsible for "eating" the organic matter in the sewage. Millions of plastic rings operate together in sewage, which can treat a large amount of harmful dirt.
In addition, Netafim, which is world-renowned for the development of drip irrigation technology, also has new products. The company's new set of wireless irrigation monitoring system can use the underground sensors and radio guidance to irrigate the appropriate amount of water to every part of the farmland.
bright future
Israel is actively selling these water technologies globally, with the goal of doubling the value of exports in 2010 to reach 2 billion US dollars.
Kogan said that ultraviolet water purification technology can be used in home swimming pools or marine fish hatcheries. Depending on the degree of purification and efficiency, product prices range from US $ 20,000 to US $ 120,000.
American environmental engineering company Hydroqual has tested this technology. Company manager Karl Shayble said: "They designed a unique reactor and the processing system proved to be very effective." This technology has been applied to an Italian food factory and a fish hatchery in Turkey.
In addition, about 30 companies worldwide have ordered Aqwise's bacterial sewage treatment system.
Reuters reported that if the UN's goal of improving global sanitation facilities in 2015 can be achieved, the world will spend about $ 10 billion annually for water treatment.
New technologies in international archives are forcing new technologies
About two-thirds of Israel ’s land is desert, and its water resources are seriously inadequate. Therefore, Israel has always attached importance to research and development of water technology.
Israel ’s first prime minister, Ben Gurion, put forward the slogan “Let the desert bloom†in the 1950s. Engineer Simche Blas called for the creation of Netafim, which developed the famous drip irrigation technology. Netafim's annual sales exceed US $ 450 million, and most of its products are sold abroad.
Odeid Distel, an official of the International Investment Department of the Israeli Ministry of Trade and Industry, said that the special environment has made Israel a global leader in water recycling. Israel has achieved recycling of 75% of its wastewater, mainly for agricultural irrigation.
Daniel Wild, a senior analyst at Swiss sustainable asset management company, said that Israel's technology in the field of irrigation and desalination is leading the world.
Wild said: "Due to lack of water resources, Israel had to pay close attention to this issue very early."
