ITEM 1.

Security and Issuer

This Amendment No. 3 to Schedule 13D (“Amendment No. 3”) relates to shares of common stock, par value $0.001 (the “Common Stock”), of LiqTech International, Inc., a Nevada corporation (the “Issuer”), formerly named Blue Moose Corporation.  The address of the principal executive offices of the Issuer is Industriparken 22C, DK 2750, Ballerup, Denmark.  Amendment No. 3 is being filed by David N. Nemelka (the “Reporting Person” or “Mr. Nemelka”) to amend and supplement the Items set forth below of the Reporting Person’s Schedule 13D filed with the Securities and Exchange Commission on September 2, 2011, as amended by Amendment No. 1 thereto filed on June 27, 2012 and Amendment No. 2 thereto filed on April 12, 2013.  All capitalized terms contained herein but not otherwise defined shall have the meanings ascribed to such terms in the Schedule 13D.

ITEM 3.

Source and Amount of Funds or Other Consideration

The Issuer has outstanding common stock purchase warrants entitling the holder to purchase one share of Common Stock for each warrant held at an exercise price of $1.50 per share at any time on or before December 31, 2016 (the “1.50 Warrants”).  In order to provide an incentive for the early exercise of the $1.50 Warrants, the Issuer offered to issue an additional Common Stock purchase warrant for each of the $1.50 Warrants exercised, which new warrant would entitle the holder to purchase one share of Common Stock for each warrant held at an exercise price of $2.70 per share at any time on or before December 31, 2016 (the “2.70 Warrants”).  On October 7, 2013, the Reporting Person exercised 647,000 of the $1.50 Warrants and on October 24, 2013, the Issuer accepted the warrant exercise.  Pursuant to a Loan and Security Agreement dated as of October 8, 2013 between the Reporting Person and Linley Ltd. (the “Holder”), the Reporting Person borrowed $1,000,000 from the Holder (the “Loan”) to pay the $970,500 exercise price for the $1.50 Warrants exercised by him.  The Loan is evidenced by a $1,000,000 secured promissory note from the Reporting Person to the Holder (the “Secured Note”), which is due on or before April 8, 2014, without interest.  The Secured Note is secured by 850,000 shares of the Reporting Person’s Common Stock.  As consideration for the Loan, the Reporting Person granted the Holder a profit sharing interest in the 850,000 shares of Common Stock and agreed to pay all profit from the sale of such shares to the Holder until such time as the Holder has received $100,000 (the “Profit Sharing Interest”).  In addition, the Reporting Person agreed to instruct the Issuer to issue directly to the Holder 167,500 of the $2.70 Warrants that were issuable upon the exercise of the Reporting Person’s $1.50 Warrants.  In the event the Reporting Person should fail to pay the Secured Note or the Profit Sharing Interest when due, the Holder could acquire investment and dispositive power with respect to some or all of the 850,000 shares of Common Stock pledged as collateral for the Loan.  The Reporting Person, Linley and a third party escrow agent (the “Escrow Agent”), entered into an escrow agreement pursuant to which the Escrow Agent agreed to hold 850,000 shares of Common Stock pledged as collateral for the Secured Note and to deliver such shares to the Reporting Person upon the timely payment of the Loan and Profit Sharing Amount or to deliver the shares to the Holder if the Reporting Person should fail to pay the Loan and Profit Sharing Amount on or before April 8, 2014.  

On November 1, 2013 the Reporting Person entered into an amended security agreement with McColee Partners LLC pursuant to which the Reporting Person pledged 497,000 shares of the Reporting Person’s Common Stock as security for a promissory note dated May 1, 2013 in the face amount of $300,000.

ITEM 4.

Purpose of Transaction

The information contained in Item 3 above is incorporated herein by reference.

The Reporting Person acquired the Common Stock for investment purposes.  In pursuing such investment purposes, the Reporting Person may further purchase, hold, vote, trade, dispose or otherwise deal in the Common Stock at such times, and in such manner, as he deems advisable to benefit from changes in market prices of the Common Stock, changes in the Issuer's operations, business strategy or prospects, or from the sale or merger of the Issuer.  To evaluate such alternatives, the Reporting Person will routinely monitor the Issuer's operations, prospects, business development, management, competitive and strategic matters, capital structure, and prevailing market conditions, as well as alternative investment opportunities, liquidity requirements of the Reporting Person and other investment considerations.  The Reporting Person may discuss such matters with management or directors of the Issuer, other shareholders, industry analysts, investment and financing professionals, sources of credit and other investors.  Such factors and discussions may materially affect, and result in, the Reporting Person modifying his ownership of Common Stock, exchanging information with the Issuer pursuant to appropriate confidentiality or similar agreements, proposing changes in the Issuer's operations, governance or capitalization, or in proposing one or more of the other actions described in subsections (a) through (j) of Item 4 of Schedule 13D.  As reported herein, the Reporting Person currently holds 293,000 of the $1.50 Warrants and 479,500 of the $2.70 Warrants.  The Reporting Person may elect to exercise some or all of the common stock purchase warrants from time to time based on various factors including the market price for the Common Stock, the exercise price of the warrants, the expiration date of the warrants and the factors discussed above with respect to the Reporting Person’s evaluation of alternatives.  In addition, the Reporting Person plans to sell shares of Common Stock from time to time to make payments on the secured notes described herein.  Except as discussed above, the Reporting Person currently has no plans to engage in the actions described in subsections (a) through (j) of Item 4 of Schedule 13D.  

The Reporting Person reserves the right to formulate other plans and/or make other proposals, and take such actions with respect to his investment in the Issuer, including any or all of the actions set forth in paragraphs (a) through (j) of Item 4 of Schedule 13D, or acquire additional Common Stock or dispose of all the Common Stock beneficially owned by him, in the public market or in privately negotiated transactions.  The Reporting Person may at any time reconsider and change his plans or proposals relating to the foregoing.
