Dyna-Aqua Copper

Dyna-Aqua Copper is a specially designed activated alumina oxide which is recommended for the isolation and removal of copper found in waste water in either a suspension or solution form.

Copper is produced as a byproduct of many industrial processes. Dyna-Aqua 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 А“ 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.

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.

Dyna-Aqua Lead

Dyna-Aqua Lead is a custom designed large particle activated alumina based metal oxide for the removal of lead from industrial wastewater with an effective size of greater than 200 microns.
It is specifically designed, modified and chemically treated in order to enhance the removal of dissolved lead from a water stream.
It is ideal for point of use applications and more cost efficient and less energy intensive than reverse osmosis, the only other commercially available point of use technology.
Dyna-Aqua Lead offers a cost efficient, simple and reliable solution for municipal, industrial and home use needs.

Dyna-AquaLead provides benefits superior to either chemical precipitation or ion exchange, commercial techniques which are costly due to the high cost of required chemicals.

Lead transported through the water system comes from:

Lead piping
Lead solder
Stabilizers used in the extrusion of PVC piping
Brass fittings which are composed of copper, zinc and lead corroding when chloramines are used to disinfect water, leading to the production of ammonia

Lead levels are monitored by the Environmental Protection Agency and cumulative exposure can lead to irreversible damage to the gastrointestinal, hematologic and nervous systems and may cause death.

Water characteristics promoting the corrosion of water include low pH, low total dissolved solids, high water temperature and high concentrations of dissolved gases such as oxygen or carbon dioxide.

Adsorption results show pH dependency with a Freundlich isotherm fit. Activated alumina possesses
both Lewis and Bronsted acidic and basic sites.
While being amphoteric alumina works best for lead removal when the pH of the aqueous stream is in the
pH range of 5.5 to 6.0.

Dyna-Aqua Fluoride

This wide pore specialized activated alumina is designed to address municipal and industrial waste water needs.
High concentrations of natural fluorides are of significance in some regions of the United States including New Mexico, West Texas, Colorado, Indiana and Illinois.
Additionally fluorides are a waste product in association with glass manufacturing, electroplating, and the production of steel and aluminum, pesticides, fertilizer and semiconductor manufacturing.
The maximum contaminant level for fluoride established by the Environmental Protection Agency is established at 4 parts per million, with a secondary standard set at 2 parts per million. Removal of fluoride from municipal and industrial waste water may be obtained by precipitation, as well as membrane and adsorption processes.
The best way, bar none, to reduce the concentration of fluoride to 1 part per million or less is through adsorption onto specially designed wide pore size activated alumina.
