One method for removing soluble zinc from acid steel plant wastewater consists of treating wastewater with a mixture of alkali-water slurry and recycled sludge formed later in the method. This mix neutralizes the acidity of the wastewater and precipitates a substantial portion of the zinc value as solids which settle out as a sludge, a portion of which is recycled as described above.

Nickel is a hazardous constituent and is not exempted. The addition of wastewaters from the zinc/nickel process will cause your filter press cake to become a “listed” RCRA hazardous waste with the F006 designation, resulting in significant increases to your disposal and regulatory costs.

Copper, nickel, ,zinc,, manganese etc. are co-precipitated in Fe oxides and cobalt, iron, nickel and ,zinc, are co-precipitated in manganese oxides (Stumm and Morgan, 1981; Noller et al., 1994). Even though chemical precipitation is a widely used method, it has the drawbacks of producing large amount of concentrated and further toxic sludge wastes, which leads to disposal problems.
