Tri-Mer - Model C/E-1 -Chrome Scrubber
Tri-Mer’s C/E-1 Chrome Scrubber scrubs all chrome, including Cr6 and Cr3, at efficiencies of 99.5% or higher, regardless of input loading. Our chrome scrubber features a multi-layer polypropylene pad system which operates under negative pressure. The filter apparatus is washed continuously in a nearly closed loop configuration. When chrome levels approach set point (generally 3000 ppm) water is forwarded to chrome recovery, or returned to the plating bath.
Tri-Mer C/E-1 chrome scrubber is a low energy system that generates less than 8" of internal static pressure, so energy consumption is extraordinarily low. Total water use is also low: average consumption is 15 gallons per hour for a 20,000 cfm unit.
C/E has no internal moving parts to wear or replace, and chrome can be recovered from both the gas stream and the filter.
The standard C/E-1 is constructed of Type 1 PVC, the material of choice for high chrome concentrations. The estimated minimum service life of the filter is five years under continuous use. The system is projected to provide ten years of continuous service before primary maintenance is required.
- The standard C/E-1 is constructed of Type 1 PVC, the material recommended for high chrome concentrations.
- Exterior flanges are PVC, angle welded to housing for standard duct hookup.
- Interior flanges are PVC, angle and structural material welded to housing.
- Liquid connections are standard PVC threaded, socket or 150# flanged.
The C/E-1 Chrome Scrubber is a low energy system which generates less than 8" of internal static pressure. Average water consumption for a 20,000 cfm unit is just 15 gpm.
C/E has no internal moving parts to wear or replace, and chrome can be recovered from both the gas stream and the filter.
The standard C/E-1 is Type I Grade 1 gray PVC, the material recommended for high chrome applications. The estimated minimum service life of a filter is 5 years under continuous use.
Chrome Scrubber Design
- Housing construction is Type I Grade 1 gray PVC, including internals.
- Material thickness is 3/16" to 3/8" PVC, structurally- reinforced depending on location.
- Exterior flanges are PVC, angle welded to housing for standard duct hookup.
- Interior flanges are PVC, angle and structural material welded to housing.
- Liquid connections are standard PVC threaded, socket or 150# flanged.
- Liquid distribution system includes 14 to 18 BETE TF Series or equal open orifice, non- clogging, spiral- type nozzles to provide complete coverage of the eliminator pad faces.
- Stage #1 packing media is cartridge type patented mist eliminator pad in polypropylene construction approximately 5" thick.
- Stage #1 irrigation is continuous.
- Stage #2 packing media is cartridge type patented mist eliminator pad in polypropylene, approximately 4" thick.
- Stage #2 irrigation is an intermittent (timed) fresh water feed. Stage #2 includes a pressure regulator, solenoid valve and cycle timers.
- Stage #3 packing media is a cartridge type patented mist eliminator pad, polypropylene construction, approximately 5" thick.
- Stage #3 irrigation is an intermittent (timed) fresh water feed. Stage #2 includes a pressure regulator, solenoid valve and cycle timers as required.
- An optional fourth stage includes a single bank of dry media filters capable of handling and operating under a completely saturated air stream. No irrigation is required on stage #4.
- Cartridge housing is constructed of formed polypropylene channel with handles. PVDF thread attaches eliminator pads to cartridge.
- Scrubber base construction is mild steel fabricated channel with epoxy coat resistant to chemicals in operational area.
- Pressure drop across each stage is read with Dwyer (or equal) magnehelic gauges.
- Inlet and outlet transitions mate with scrubber unit and are structurally- reinforced Type 1 Grade 1 gray PVC.
