Metal Removal Technology to Lower Dissolved Copper We have developed technologies that can lower dissolved copper to less that 2 parts per billion (2 ppb) in your effluent. Read More Technology to Lower Zinc Our treatment technology allows us to treat and remove dissolved zinc to less than 20 parts per billion (20 ppb) in your effluent. Read More Technology to Lower Dissolved Hexavalent Chrome Using our technology, we can convert hexavalent chrome to trivalent chrome which can be easily removed with conventional treatment. Read More Technology to Lower Other Heavy Metals Using our technology, we are able to increase metal removal. We generate better removal than conventional metal hydroxide treatment. Read More
