Treatment Of Heavy Metal Containing Wastewater
- Aug 10, 2018 -

In electroplating and alloy production, it is often necessary to rinse with a large amount of water containing a relatively high concentration of heavy metals such as nickel, iron, copper and zinc. In order to meet the emission requirements of these heavy metal-containing wastewaters, the general measure is to treat these heavy metals into hydroxide precipitates for removal. If the nanofiltration membrane technology is adopted, not only 90% of the wastewater can be recovered, but also the heavy metal ion content can be concentrated by 10 times, and the concentrated heavy metal has the value of recycling.
