assay of ferrous sulphate

..., which is a dimensionless quantitative figure, and has a good linear relationship with the assay and size of the abrasive particles in the sample. Because the PQ index is more sensitive to large-size ferromagnetic abrasive particles, it is usually used in

... with more than 10 years, with very good stability. Lots of textile mills are using ferrous sulphate and lime for textile effluent treatment, our color removal chemical can replace it, much higher efficiency, low dosage, and low volume sludge. It is a
