Abstract
Aspects of a chemical capture system for removing metals from a contaminated waste stream, are disclosed including a means for controlling the flow rate of the contaminated waste stream through the chemical capture system, a prefiltration stage, and a lead-lag system comprising a disposable chemical filtration cartridge in either the lead or the lag position.
Claims20
A chemical capture system for removing metals from a contaminated waste stream, comprising:
- (i) a prefiltration stage;
- (ii) a lead-lag system comprising a filtration device in either the lead or the lag position;
- and
- (iii) a means for controlling the flow rate of the contaminated waste stream through the chemical capture system.
A chemical capture system for removing metals from a contaminated waste stream, comprising:
- (i) a prefiltration stage;
- (ii) a dual lead-lag system comprising filtration devices, wherein at least one of the filtration devices comprises cation exchange media;
- and
- (iii) a badger flow meter and control system for controlling the flow rate of the contaminated waste stream through the chemical capture system;
- wherein the prefiltration stage is positioned upstream of the lead-lag system;
- and
- wherein the filtration device comprising the cation exchange media is configured to be wholly incinerated for recovery of at least some of the metals removed from the contaminated waste stream.
A method of chemical capture for removing metals from a contaminated waste stream, the method comprising:
- (i) prefiltering the contaminated waste stream to produce a first contaminated effluent;
- (ii) filtering the first contaminated effluent via a dual lead-lag system comprising a plurality of filtration devices, wherein at least one of the plurality of filtration devices comprises cation exchange media;
- and
- (iii) controlling the flow rate of the contaminated waste stream or the contaminated effluent through the chemical capture system via a badger flow meter and control system;
- (iv) removing the at least one of filtration devices;
- and
- (v) wholly incinerating the at least one of filtration devices for recovery of at least some of the metals removed from the contaminated waste stream.
