The former is not suitable for treatment of the liquid arsenic waste. 10 The transformation of As(III) and As(V) into arsenic minerals with low solubility and high stability is a feasible technology for high-arsenic waste acid treatment. 1 The Ca- and Fe-associated compounds are the main minerals for arsenic immobilization. 11 The formation of calcium arsenate in a Ca(II)–As(V)–H 2 O system could obviously …

One potentially attractive approach to the destruction of chemical agents is chemical hydrolysis (i.e., reaction with water to form products of reduced toxicity). Because some of the reaction products are acids, a base such as lime or sodium hydroxide is generally used to neutralize the acidic products, hence, the generic description of the process ...

14 Industrial Wastewater Treatment Principals and Ideas

For neutralization treatment,, the principle of waste ,treatment, should be considered first. For example, ,acid, or alkali ,wastewater, neutralizes each other or neutralizes acidic ,wastewater, with waste alkali (slag), and neutralizes alkaline ,wastewater, with waste ,acid,. In the absence of these conditions, a neutralizing agent ,treatment, can be employed. 13.
