Copper is produced as a byproduct of many industrial processes. Dyna-AquaTM Copper is designed especially for the recovery of copper from spent solutions produced in printed circuit (wiring) board manufacture and electroplating

It is currently thought that one difficulty in the commercial removal of copper from solution is that the metal forms into complexes such as with benzotriazoles or other triazoles. Activated alumina oxides are able to address this issue and remove the complex by the process of adsorption with high efficiency.. Adsorption is defined as the interphase transfer of material from a homogeneous or heterogeneous fluid matrix onto a solid surface.

Unlike organic pollutants, the major of which are susceptible to biological degradation, copper is not biodegradable into a nontoxic end product. It must be reduced to acceptable levels prior to being discharged into the environment in order for manufacturers to be in compliance with the Federal Clean Water Act, with the federal regulatory limit for discharged copper in suspension or solution being 1.3 mg/Liter.

Furthermore competitive commercially available technologies such as ion exchange, chemical precipitation, ultafiltration and electrochemical deposition are costly chelating and ion exchange resins are expensive.

The ideal solution to clean up of industrial wastewater would be to find an adsorbent which could avoid the need for co-precipitation and pH adjustment. The sorption of copper is highly pH dependent with an increase in the amount of adsorption with increasing pH.

Dyna-AquaTM Copper is an ideal medium for copper removal from wastewater. The amphoteric property of specialty activated alumina is able to do away without the need for the coprecipitant, and the compound is able to enhance copper removal as the pH of the solution increases.
