    Registration Statement on Form S-1 (Registration No. 333-178837)

    Acceleration Request

Dear Mr. Slivka:

Pursuant to Rule 461
of the Rules and Regulations promulgated under the Securities Act of 1933, as amended, LiqTech International, Inc. (the “Company”)
hereby respectfully requests that the effectiveness of the above-captioned Registration Statement on Form S-1 be accelerated to
Monday, February 13, 2012, at 4:30 p.m. Eastern Time, or as soon as practicable thereafter.

The Company acknowledges
that:

 · should the Securities and Exchange Commission (the “Commission”) or the staff, acting
pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with
respect to the filing;

 · the action of the Commission or the staff, acting pursuant to delegated authority, in declaring
the filing effective, does not relieve the Company from its full responsibility for the adequacy and accuracy of the disclosure
in the filing; and

 · the Company may not assert staff comments and the declaration of effectiveness as a defense in
any proceeding initiated by the Commission or any person under the federal securities laws of the United States.

The cooperation of
the staff in meeting the timetable described above is very much appreciated.
