Resource utilization of pickling wastewater (waste acid)
Resource utilization of pickling wastewater (waste acid)

A large number of pickling wastewater (waste acid) will be produced in iron and steel processing enterprises. The concentration of heavy metal ions in this kind of wastewater is high. As long as the concentration of heavy metal ions can be reduced, the regenerated acid can be returned to the pickling section for recycling.

Acid, rock drainage can also result when affected rock is used as fill material. The low pH and ,high concentration, of metals are an environmental concern for several reasons: Aquatic species don’t tolerate changes in pH. In mine drainage, the low pH allows metals to dissolve into the water, and metals in ,high, enough concentrations can be toxic.

Bipolar membrane method is a kind of membrane separation method, which is suitable for the treatment of acid pickling wastewater (waste acid) with high acid concentration. Membrane separation is a highly efficient process for the separation of metal ions and acids with high selectivity of membrane to ions, which can fully recover acids and metal salts.

Total dissolved solids, (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form.TDS concentrations are often reported in parts per million (ppm). Water TDS concentrations can be determined using a digital meter.

Because of its high concentration in most wastewater, chloride is often the most serious source of interference. Its reaction with potassium dichromate follows the equation: 6 C l − + C r 2 O 7 2 − + 14 H + → 3 C l 2 + 2 C r 3 + + 7 H 2 O {\displaystyle \mathrm {6Cl^{-}+Cr_{2}O_{7}^{2-}+14H^{+}\rightarrow 3Cl_{2}+2Cr^{3+}+7H_{2}O} }
