1. A method for sealing a membrane module, comprising: placing a sealing ring having a T-shaped cross section between a head plate configured to hold a tube bundle and a mounting ring configured to hold the head plate so that a first leg of the sealing ring is in contact with a circumferential surface of the mounting ring and a circumferential surface of the head plate and a second leg of the sealing ring is in contact with an axial surface of the head plate;placing an auxiliary ring against the sealing ring so that the second leg of the sealing ring is in contact with an axial surface of the auxiliary ring and a third leg of the sealing ring is in contact with a circumferential surface of the auxiliary ring and the circumferential surface of the mounting ring;causing the first leg of the sealing ring to circumferentially seal at least a portion of the head plate; andcausing the second leg of the sealing ring to axially seal at least the portion of the head plate. 2. The method according to claim 1, wherein the sealing ring extends axially in the manner of a strip. 3. The method according to claim 1, wherein the first leg of the sealing ring is inserted radially between the head plate and the mounting ring, the second leg of the sealing ring is braced axially against the axial surface of the head plate, and the third leg of the sealing ring is braced radially against the circumferential surface of the mounting ring by the auxiliary ring. 4. The method according to claim 1, wherein the auxiliary ring is braced axially against the head plate. 5. The method according to claim 4, wherein the auxiliary ring is braced against a cap overlapping the head plate by a force of a spring. 6. The method according to claim 1, wherein the auxiliary ring provides a radial or axial spring force. 7. The method according to claim 1, wherein causing the sealing ring to circumferentially seal at least the portion of the head plate or causing the sealing ring to axially seal at least the portion of the head plate includes injecting a sealing mass between the head plate and the mounting ring. 8. The method according to claim 5, wherein the auxiliary ring provides a radial or axial spring force. 9. The method according to according to claim 7, wherein a quartz sand is added to the sealing mass. 10. The method according to claim 6, wherein the auxiliary ring is corrugated to provide the spring force. 11. A method for sealing a membrane module, comprising: placing a sealing ring having a T-shaped cross section against a head plate configured to hold a tube bundle so that a first leg of the sealing ring is configured to circumferentially seal at least a portion of the head plate and a second leg of the sealing ring is configured to axially seal at least the portion of the head plate;bracing an auxiliary ring against the sealing ring, such that the sealing ring has a chamfered surface located between the second leg of the sealing ring and a third leg of the sealing ring when the sealing ring is in contact with the auxiliary ring;causing the first leg of the sealing ring to circumferentially seal at least the portion of the head plate; andcausing the second leg of the sealing ring to axially seal at least the portion of the head plate. 12. The method according to claim 11, which includes placing the sealing ring between a mounting ring and the head plate. 13. The method according to claim 12, which includes placing the sealing ring so that the mounting ring radially braces the first and third legs of the sealing ring. 14. The method according to claim 12, which includes placing the sealing ring so that the mounting ring contacts the first and third legs of the sealing ring. 15. The method according to claim 11, wherein the auxiliary ring is axially braced against the head plate. 16. The method according to claim 15, wherein the auxiliary ring is braced against a cap overlapping the head plate by a force of a spring. 17. The method according to claim 11, wherein the auxiliary ring provides a radial or axial spring force. 18. The method according to claim 17, wherein the auxiliary ring is corrugated to provide the spring force.
