Recently, Japan’s “FujiSankei Business i.†reported that Japan’s synthetic fiber and other manufacturers developed the “membrane†technology developed by Japan and jumped out of the “water only†consciousness in Japan, seeking business opportunities in the world and applying chemical fiber manufacturers to overseas desalination. And water treatment and other water treatment operations.
In the Middle East countries where the so-called "water is more expensive than oil," the "evaporation method" that has been used to evaporate and separate the salt from seawater that has been burnt with oil has hitherto been the mainstream. However, due to the rising cost of crude oil, the RO method is rapidly expanding. In Saudi Arabia, the amount of water produced in 2005 has grown to 15%.
The RO membrane removes ions, such as molecular grade impurities, by ultrafine pores that extend nylon-like synthetic materials up to 0.2 microns. Used for pasting with polyester non-woven fabrics, etc., to increase the strength, it is a structure that separates the ultra-pure water and the contaminated water from the high-pressure water pipe that rolls the membrane into an umbrella shape inside. It is the most advanced water treatment technology than the "filtration method" in which the membrane overlaps the filter. Moreover, equipment costs are about half of the evaporation method, while the desalination rate is four times and the energy consumption is one-fifth. The cost of desalination per unit is about 20% cheaper, and the difference is increasing due to the high cost of crude oil.
Japanese manufacturers take pride in the overwhelming share of RO membrane's world market of about 70%. Originally, the RO membrane was developed in the United States as a national policy in the 1960s, and DuPont et al. Although Japan, which is enjoying water resources, began to be late, the demand for semiconductor manufacturing using ultrapure water in the 1980s expanded, formalizing production and accumulating technology.
In overseas countries, not only seawater but also domestic wastewater is used to ensure the development of drinking water. The demand for "Nanofiltration (NF) membrane" and "Ultrafiltration-free (UF) membrane" to remove viruses and bacteria that are more salty than seawater is expanding, and Japanese products are very popular.
Furthermore, between Japanese manufacturers, the synergies of cooperation have resulted in the improvement of technology and the enhancement of advantages.
In February, Kuraray teamed up with Nomura Micro Science, which has cultivated industrial ultrapure water equipment, and began to combine drainage and recycling of Kuraray Membrane Technology and Nomura Equipment Technologies. Kuraray’s President Ito Iwana is looking forward to “scheduled 2015 sales to increase from 15 billion yen to 20 billion yen, with the fastest growth.â€
Mitsubishi Rayon Co., Ltd. and Nitto Denko also joined hands last year and sought to strengthen their competitiveness through mutual supplements such as "membrane" cooperation. Mitsubishi placed the water treatment business in a next-generation core business that goes hand in hand with automotive-related businesses that use carbon fiber, and President EBARA Masahiro said that it will work hard to "promote cooperation and expand business development in Asia and Europe."
