"Advanced Membrane Separation Technology"

Acid Purification
Diffusion Dialysis Technology:

Mech-Chem Associates, Inc.’s Acid Purification (AP) Systems are simple to operate, dependable, and economical. Our AP Systems use an advanced membrane separation technology known as Diffusion Dialysis to separate, recover, and purify strong acids from spent acid solutions contaminated with dissolved metals. An anion exchange membrane serves as a semi-permeable barrier between a flowing stream of water and a flowing stream of process acid. Through this membrane, the processes of both Diffusion and Dialysis occur. These processes are carried out hundreds of times through the numerous internal channels that are contained in the many layers that make up the centrally-located stack of the Acid Purification System.

This acid purification technology is capable of recovering acids from concentrated baths that would have been discarded in the past. The purified acid is returned to the process tank for continued use, while a concentrated metal-containing aqueous solution is removed for waste treatment. Typically, 80-90% of the available acid is recovered in one pass through the AP System, with 70-90% of the dissolved metals removed from this process acid in the same pass through. The Acid Purification Systems manufactured by Mech-Chem Associates, Inc. are tailored to the client’s needs with respect to materials of construction and operating capacity required.
