In the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position, results of operations and cash flows at June 30, 2015 and 2014 and for the periods then ended have been made. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. It is suggested that these condensed consolidated financial statements be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s December 31, 2014 audited consolidated financial statements. The results of operations for the periods ended June 30, 2015 and 2014 are not necessarily indicative of the operating results for the full year. Consolidation -- Functional Currency / Foreign currency translation -- accumulated as a component of other comprehensive income in stockholders’ equity. Transaction gains and losses that arose from exchange rate fluctuations from transactions denominated in a currency other than the functional currency are included in the statement of operations as incurred. Cash, Cash Equivalents and Restricted Cash -- Accounts Receivable -- The roll forward of the allowance for doubtful accounts for the six months ended June 30, 2015 and the year ended December 31, 2014 is as follows: 2015 2014 Allowance for doubtful accounts at the beginning of the period $ 1,654,290 $ 608,356 Bad debt expense 12,784 216,919 Amount of receivables written off (185,224 ) (42,117 ) Acquired subsidiary - 951,354 Effect of currency translation (199,185 ) (80,222 ) Allowance for doubtful accounts at the end of the period $ 1,282,665 $ 1,654,290 Inventory -- Property and Equipment -- Long-Term Investments -- Intangible Assets -- Goodwill -- Goodwill is evaluated for impairment annually, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows. Revenue Recognition and Sales Incentives -- The Company has received long-term contracts for the installation of various water filtrations systems and grants from Government entities for development and use of silicon carbide membranes in various water filtration and treatment applications. Revenues from long-term contracts and grants are recognized on the percentage-of-completion method, measured by the percentage of project costs incurred to date to estimated total project costs for each long-term contract or grant multiplied by the long-term contract or grant income on a project by project basis. This method is used because management considers costs incurred to be the best available measure of progress on contracts in process. Project costs of the long-term contracts and grants include all direct material and labor costs and those indirect costs related to the project. Project costs are capitalized and accreted into cost of sales based on the percentage of the project completed. Should a loss be estimated on an incomplete project it would be recorded in the period in which such a loss is determined. Changes in estimated profitability of a project are recognized in the period in which the revisions are determined. The aggregate of costs incurred and income recognized on incomplete projects are recorded as costs in excess of billings and are shown as a current asset. The aggregate of billings in excess of related costs incurred and income recognized on projects is shown as a current liability. In Denmark, Value Added Tax (“VAT”) of 25% of the invoice amount is collected in respect of the sales of goods on behalf of tax authorities. The VAT collected is not revenue of the Company; instead, the amount is recorded as a liability on the balance sheet until such VAT is paid to the authorities. Advertising Cost -- Research and Development Cost -- 365,457 and $140,419, respectively, of research and development costs. Income Taxes -- Income (Loss) Per Share -- Stock Options -- Fair Value of Financial Instruments -- ● Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities; ● Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and ● Level 3. Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, accounts receivable, prepaid expenses, investments, accounts payable, accrued expenses, capital lease obligations and notes payable approximates their recorded values due to their short-term maturities. Accounting Estimates -- contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated. Recent Accounting Pronouncements -- Other recent accounting pronouncements issued by the FASB did not or are not believed by management to have a material impact on the Company’s present or future financial statements.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	NOTE 11 – INCOME TAXES The Company accounts for income taxes in accordance with FASB ASC Topic 740, Accounting for Income Taxes; which requires the Company to provide a net deferred tax asset or liability equal to the expected future tax benefit or expense of temporary reporting differences between book and tax accounting and any available operating loss or tax credit carry forwards. The amount of and ultimate realization of the benefits from the deferred tax assets for income tax purposes is dependent, in part, upon the tax laws in effect, the Company’s future earnings, and other future events, the effects of which cannot be determined. The temporary differences, tax credits and carry forwards gave rise to the following deferred tax asset (liabilities) at June 30, 2015 and December 31, 2014: 2015 2014 Vacation accrual $ 5,077 $ 5,077 Allowance for doubtful accounts 13,955 13,955 Long term contracts - - Reserve for obsolete inventory 53,260 90,605 Net current tax assets $ 72,292 $ 109,637 Business tax credit carryover 25,709 25,709 Deferred compensation 171,614 171,615 Net operating loss carryover 4,866,950 4,001,198 Excess of book over tax depreciation (586,717 ) (583,735 ) Valuation Allowance (123,829 ) (118,328 ) Long term deferred tax asset $ 4,353,727 $ 3,496,459 In accordance with prevailing accounting guidance, the Company is required to recognize and disclose any income tax uncertainties. The guidance provides a two-step approach to recognizing and measuring tax benefits and liabilities when realization of the tax position is uncertain. The first step is to determine whether the tax position meets the more-likely-than-not condition for recognition and the second step is to determine the amount to be recognized based on the cumulative probability that exceeds 50%. The amount of and ultimate realization of the benefits from the deferred tax assets for income tax purposes is dependent, in part, upon the tax laws in effect, the Company’s future earnings, and other future events, the effects of which can difficult to determine and can only be estimated. Management estimates that it is more likely than not that the Company will generate adequate net profits to use the deferred tax assets; management has estimated that all of the deferred tax will be realized and consequently, a valuation allowance was not recorded. A reconciliation of income tax expense at the federal statutory rate to income tax expense at the Company’s effective rate is as follows for the six months ended June 30, 2015 and 2014: 2015 2014 Computed tax at expected statutory rate $ (1,337,022 ) $ (752,797 ) State and local income taxes, net of federal benefits - (24,704 ) Non-deductible expenses 49,587 40,763 Non-US income taxed at different rates 288,402 41,178 Valuation Allowance 31,929 - Income tax benefit $ (967,104 ) $ (695,560 ) The components of income tax expense (benefit) from continuing operations for the six months ended June 30, 2015 and 2014 consisted of the following: 2015 2014 Current income tax expense: Danish $ - $ - Korean - - Federal - - State - - Current tax (benefit) $ - $ - Book in excess of tax depreciation $ - $ - Net operating loss carryover (999,033 ) (757,272 ) Valuation allowance 31,929 - Reserve for obsolete inventory - 61,712 Deferred tax expense (benefit) $ (967,104 ) $ (695,560 ) Total tax expense (benefit) $ (967,104 ) $ (695,560 ) Deferred income tax expense / (benefit) results primarily from the reversal of temporary timing differences between tax and financial statement income. The Company files Danish and U.S. federal and Minnesota state income tax returns. LiqTech International AS is generally no longer subject to tax examinations for years prior to 2009 for their Danish tax returns. LiqTech NA is generally no longer subject to tax examinations for years prior to 2011 for U.S. federal and U.S. state tax returns.

We have recorded non-cash compensation expense of $39,868 for the period ended June 30, 2015 related to the warrants issued. The exercise price of the warrants and the number of shares underlying the warrants are subject to adjustment for stock dividends, subdivisions of the outstanding shares of common stock and combinations of the outstanding shares of common stock. For so long as the warrants remain outstanding, we are required to keep reserved from our authorized and unissued shares of common stock a sufficient number of shares to provide for the issuance of the shares underlying the warrants. On June 4, 2015, the Company issued to Wolfe Axelrod Weinberger Associates, LLC a warrant to purchase 200,000 shares at an exercise price of $1.00 per share.

Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill -- Goodwill is evaluated for impairment annually, and whenever events or changes in circumstances indicate the carrying value of goodwill may not be recoverable. Triggering events that may indicate impairment include, but are not limited to, a significant adverse change in customer demand or business climate that could affect the value of goodwill or a significant decrease in expected cash flows.
Revenue Recognition, Policy [Policy Text Block]	Revenue Recognition and Sales Incentives -- The Company has received long-term contracts for the installation of various water filtrations systems and grants from Government entities for development and use of silicon carbide membranes in various water filtration and treatment applications. Revenues from long-term contracts and grants are recognized on the percentage-of-completion method, measured by the percentage of project costs incurred to date to estimated total project costs for each long-term contract or grant multiplied by the long-term contract or grant income on a project by project basis. This method is used because management considers costs incurred to be the best available measure of progress on contracts in process. Project costs of the long-term contracts and grants include all direct material and labor costs and those indirect costs related to the project. Project costs are capitalized and accreted into cost of sales based on the percentage of the project completed. Should a loss be estimated on an incomplete project it would be recorded in the period in which such a loss is determined. Changes in estimated profitability of a project are recognized in the period in which the revisions are determined. The aggregate of costs incurred and income recognized on incomplete projects are recorded as costs in excess of billings and are shown as a current asset. The aggregate of billings in excess of related costs incurred and income recognized on projects is shown as a current liability. In Denmark, Value Added Tax (“VAT”) of 25% of the invoice amount is collected in respect of the sales of goods on behalf of tax authorities. The VAT collected is not revenue of the Company; instead, the amount is recorded as a liability on the balance sheet until such VAT is paid to the authorities.

Unless otherwise disclosed, the fair value of the Company’s financial instruments including cash, accounts receivable, prepaid expenses, investments, accounts payable, accrued expenses, capital lease obligations and notes payable approximates their recorded values due to their short-term maturities.
