Get Price2021-1-4 · Dredged mud is a kind of construction material that can be reused as waste. It needs to be dehydrated before it is used. At present, plate and frame pressure filtration (hereafter referred to as PFP) using lime for conditioning after flocculation is widely employed. The addition of lime causes the mud cake to exhibit a high pH, and reduces its subsequent use.

Get Price1996-8-1 · Formic acid is added to the whole mud to lower the pH of the fluid, and to partially dissolve the calcareous filter cake material in the mud. Calcium carbonate is a typical ingredient of the formate mud composition, or it is added in small quantities if not present. The dissolved calcium can help to flocculate the polymers during the pH adjustment.
