Yes — raising wastewater pH to the appropriate level (typically 8.5–10.5 depending on the metal) causes dissolved heavy metals such as zinc, copper, nickel, and chromium to precipitate as insoluble metal hydroxides that can be removed by downstream filtration or settling.
PRAB pH Adjustment Systems support metal hydroxide precipitation as part of the standard batch neutralization cycle, helping facilities meet both POTW discharge limits and RCRA hazardous waste de-listing requirements.
