Dear Sir,

I am supplier of filter cartridges being used in the filtration of fluid in any Industrial application, in this context one of my client is producing chromium sulphate for the use in leather tanning but during the process he is facing problem to remove carbon particles from chromium sulphate solution, the particle size is 1 to 5 micron but are small in quantity, kindly suggest remedy to remove these carbon particles.

Thanks,

Generally, small particles are removed by using a precoat on the filter--a slurry of diatomaceous earth, cellulose grit, or other material compatible with the solution.
