Method of heavy metal removal from industrial wastewater using submerged ultrafiltration or microfiltration membranes |
| abstract |
A method of removing one or more heavy metals from industrial wastewater by a disclosed membrane separation process. Specifically, the following steps of: (a) collecting an industrial wastewater containing heavy metals in a receptacle (b) adjusting the pH so said system to achieve hydroxide precipitation of said heavy metal in said industrial wastewater (c) adding an effective amount of a water soluble ethylene dichloride-ammonia polymer having a molecular weight from 500 to 10,000 daltons that contain from 5 to 50 mole percent of dithiocarbamate salt groups to react with said heavy metals in said industrial wastewater system (d) passing said treated industrial wastewater through a submerged membrane, wherein said submerged membrane is an ultrafiltration membrane or a microfiltration membrane and (e) optionally back-flushing said membrane to remove solids from the membrane surface. |
