After a detailed and complex inspection, atech innovations gmbh received the 3-A-symbol authorization. This quality label is evidence of the highest approval level under food and drug regulations worldwide. The approval covers atech's ceramic membranes as well as the stainless steel modules housing the membranes.

The standards to be met for this much sought-after certification are laid down by 3-A Sanitary Standards, Inc., a US nonprofit organization, in cooperation with the United States Public Health Service (USPHS ), the United States Food and Drug Administration (USFDA), the United States Department of Agriculture (USDA), and the European Hygienic Engineering & Design Group (EHEDG).

The inspection procedure took one year in total. atech passed all tests successfully and is now authorized to apply the 3-A-symbol to its products. The symbol is an accepted proof of quality and reliability and its application is required by many clients, especially in the United States. The food processing industry has a particular need for certainty that production equipment cannot cause any contamination or adversely affect quality.

Products made by atech innovations gmbh were 'put to the acid test' by an independent expert, a 'Hygienic Design Consultant' trained by 3-A. During a total of 3 visits to atech's head office in Gladbeck matters such as the execution of weld seams on the stainless steel casings, surface roughness of the casing material, the sealing type and, of course, the ceramics themselves were inspected down to the last detail. An exact documentation was required, covering not only the materials - such as stainless steel, gaskets, sealing wax - but also the grain of the high-purity alpha aluminum oxide that that had been used. Uninterrupted traceability must be ensured at any time. Some materials had to be additionally certified according to 3-A standards by an independent expert.

There are only three other manufacturers of cross flow membranes in the world who have been authorized to use the 3-A symbol. With this symbol atech can now prove beyond all doubt that its products are of top quality, as they have always been. Operators of plants with atech products are thus on the safe side. Especially in the US food industry this symbol is almost a must-have in order to win contracts for, e.g., processing of milk and whey. But in Europe as well, the symbol is known and is a proof of verified top quality.
