HYDRANAUTICS reverse osmosis membrane ESPA series

　　HYDRANAUTICS reverse osmosis membrane ESPA series

　　Detailed descriptions：

　　Ultralow-pressure saving-energy reverse osmosis compound

　　Japanese electro-technical group/ American HYDRANAUTICS ESPA series is the most successful ultralow-pressure saving-energy reverse osmosis membrane component in the world. In 1980s, the two countries have noted that energy-shortage will become the focus of all over the world, then, they devoted themselves to research and development, finally, in 1995, the first ultralow-pressure saving-energy reverse osmosis membrane component ESPA is produced, the same capacity is carrying out while electricity consumption is saving 30%.

　　The applications of ESPA series reverse osmosis membrane component are not only used in barred/bottled drinking pure water preparations, but also second-stage of many double-stage reverse osmosis systems, even the recycle items of municipal waste water treatment, ESPA series also is the optimal choice in view of extremely energy consumption and outstanding antipollution ability.

　　Through market research, Japanese electro-technical group/American HYDRANAUTICS has been developing new membrane components, in order to satisfy the new requirements of market, one of ESPA series reverse osmosis membrane component is ESPAB, ESPAB developed and manufactured is to satisfy the requirements of boron removal in sea water desalinization system, in sea water, the boron content is high(5-7mg/L), just first-stage sea water desalinization reverse osmosis system is not enough, the boron content in output can not meet the security restrictions provided by the World Health Organization and the majority of countries(0.5mg/L). Therefore, when the boron content is strictly limited, we add high boron-removal component after sea water desalinization reverse osmosis system, become the second-stage reverse osmosis system, which will help you get the secure fresh water.

　　●espa1

　　Standard super low-pressure saving-energy reverse osmosis membrane component, harmonious output and desalinization.

　　●espa2

　　super low-pressure saving-energy reverse osmosis membrane component of high desalinization, which can satisfy the higher requirements of output quality.

　　●espa2+

　　Based on espa2, we enlarged effective membrane area(440∞, which has been widely used second-stage of double-stage reverse osmosis).

　　●espa4

　　Ultra low-pressure saving-energy reverse osmosis membrane components of maximum output flux can reach 72.6t/MPa under the standard test condition, desalinized water can be gotten under the extremely low operation pressure. On the aspect of reducing energy consumption, there is no reverse osmosis membrane component beyond its performances.

　　●espab

　　The only professional ultra low-pressure saving-energy reverse osmosis membrane component of removing boron in the world. There are the strict rules to the boron density in sea water desalinization system, ESPAB can be seen as membrane component of double-stage reverse osmosis system, which can help you get stable and low baron content fresh water.

　　Espa1-4040, espa2-4040, espa4-4040 and 4-inch ESPA series reverse osmosis membrane component, which can be used in preparation of potable pure water.
