Abstract: Provided are a spiral type membrane element that can re-collect the electric power that is used in a good manner, and a spiral type membrane filtering device having the same. The spiral type membrane element comprises a power generating section that generates electric power by using a liquid, and an electric power outputting section that outputs, either in a wired manner or in a wireless manner, the electric power supplied from said power generating section. The electric power that is generated in the power generating section using the liquid (raw water, permeated water, or concentrated water) can be output from the electric power outputting section in a wired manner or in a wireless manner. Therefore, the electric power that is output from the aforesaid electric power outputting section can be used in an electric component disposed outside or can be stored into a capacitor section disposed outside.

Abstract: Provided are a spiral type membrane filtering device by which an electric component can be re-used and a mounting member, as well as a membrane filtering device managing system and a membrane filtering device managing method using the same. An interconnector (42) attachable and detachable to a membrane element is provided with a sensor that detects the property of liquid such as raw water or permeated water that flows within a membrane filtering device, or a power generating section (26). Therefore, even if the membrane element is to be replaced, the sensor or the power generating section (26) can be re-used by re-mounting the interconnector 42 onto a new membrane element. Also, since there is no need to add a change to the membrane element, a conventional membrane element can be used as it is.

Abstract: Provided are a spiral type membrane element that can ensure a larger amount of electric power without performing a cumbersome work and a spiral type membrane filtering device having the element, as well as a membrane filtering device managing system and a membrane filtering device managing method using the device. The spiral type membrane element comprises a sensor for detecting a property of liquid, a power generating section that generates electric power by using said liquid, and a wireless transmitting section that receives the electric power supplied from said power generating section and wirelessly transmits a detection signal from said sensor. By generating electric power in the power generating section with use of the liquid detected by the sensor, a larger amount of electric power can be ensured without performing a cumbersome work.

Abstract: Embodiments of the present invention comprise reverse osmosis filters and systems comprising embedded radio frequency identification (RFID) tags for storing and retrieving data. The RFID tags can be preferably embedded under a filtration device's protective outer shell. Information can be easily stored onto and retrieved from the embedded RFID tags. The ability to easily store and retrieve data from the embedded RFID devices facilitates the creation of loading maps, monitoring, addition, and replacement of fluid filtration devices.

Abstract: The present disclosure relates to a system comprising integrated sensors (169, 170) for measurement of permeate flow and permeate conductivity of individual membrane elements (163) while they are in operation in an RO unit. The flow and conductivity measuring integrated sensors (169, 170) are of a small size that enables them to be inserted into the permeate tube (172) of connected membrane elements (163) during RO unit operation. Measured flow and conductivity information is transferred to the recording device (174) through electric wires or through wireless transmission.

Abstract: A liquid separation tube having a tubular membrane inside of a porous support tube and an end part which is insertable into a coupling member has a seal structure which allows the use of a relatively thin adapter which is to be inserted within a packing. In the seal structure, annular grooves are provided on either the outside circumferential wall of the adapter or the inside circumferential wall of the packing and passages are formed through the adapter in the vicinity of the annular grooves so that a pressurized feed solution can expand the packing in the vicinity of the annular grooves to provide a seal between the packing and the tubular membrane.
