Therefore, by combining oxalic acid and FA, Cr(VI) can be removed from wastewater and its environmental toxicity can be reduced simultaneously. In this study, we investigated a two-step method to eliminate Cr( VI ) from wastewater; in detail, the first step included the reduction of Cr( VI ) to Cr( III ) in the presence of oxalic acid, followed by the adsorption of Cr( III ) onto MFA.

The content of H2S, NH3 and phenol in the phenol containing acid wastewater produced by the direct coal liquefaction project is high. The concentration of H2S, NH3 and phenol can reach the biochemical treatment range by adopting double tower stripping and isopropyl ether extraction.

PHYSICAL AND CHEMICAL WASTEWATER TREATMENT METHODS
PHYSICAL AND CHEMICAL WASTEWATER TREATMENT METHODS

Neutralization may be used in order to treat acid wastewaters containing metals, the method comprising increasing the pH of the acid waste by addition of an alkaline reagent, to form a precipitate and collecting the precipitate. This way the incoming solution is pH adjusted to the optimum range for precipitating metals as hydroxides.
