Chrome Scrubber

Chrome Scrubber

All-mechanical system operates without chemicals

 

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.

System Design

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 19 L per hour for a 34000 m³/h unit. The C/E-1 chrome scrubber has no internal moving parts to wear or replace. Chrome can be recovered from both the gas stream and the filter.

Installation

Our chrome scrubber is simple to install and operate and is available in single units with capacities to 85000 m³/h. Installation can be accomplished by Tri-Mer or by plant personnel. Tri-Mer provides a standard skid-mounted package which includes duct connections, controls interfacing, fan, recirculation tank, pump and piping.

Long Service Life

The standard C/E-1 is constructed of Type 1 PVC, the material recommended for high chrome concentrations. The estimated minimum service life of the filter is five years under continuous use. The system averages ten years of continuous service before primary maintenance is required.
