Definitions
- a nano-filtration material can be used instead of the two anion exchange materials.
- the solution is typically first contacted with the two cation exchange materials as described above (where the same conditions with respect to pH values and temperature applies). It should be understood that the pH value of the solution resulting from contacting with the first cation exchange material typically needs to be adjusted before contacting with the second cation exchange material, cf. the instructions given above. After passage of those two cation exchange materials, essentially all metal ions are removed and the pH value is normally in the range of 0.8 to 1.4. The pH value should typically, e.g. after adjustment with the acids or bases mentioned above, be in the range of 2.0 to 3.0 before contacting with the nano-filtration material.
- the temperature of the acidified solution when contacted with the first (cat)ion exchange material is typically 30-60°C, preferably 35-45°C, due to the fact that the warm acidic solution is used directly from the mixer without storage.
- the temperature of the resulting solutions when contacted with the succeeding three ion exchange materials are contingent on the temperature of the surrounding which is generally within 0-30°C, preferably 15-25°C. For temperatures below 0°C, precipitation may make up a considerable problem.
- ion-exchange materials mentioned above the person skilled in the art will be able to suggest other equally applicable ion-exchange materials according to the specifications given herein with respect to pH value intervals, specificity for the specified types of ions, temperature intervals, etc.
- the solution for regeneration of the second cation exchange material is lead to the vessel containing the material T from a tank U.
- the recovered heavy metal solution is lead to a storage tank for destruction or further work-up through a pipeline V.
- the remainder of the treated solution after passage through all four ion exchange materials is lead to a waste water purification plant through a pipeline X.
- each of the four ion exchange materials are arranged into two separate compartment e.g. Kl, KM, Nl, Nil, Ql, Qll and Tl, TM.
- This arrangement allows one part of the ion exchange materials e.g. Kl, Nl, Ql and Tl, to be brought in contact with the solution being treated, while the other part of the ion exchange materials e.g. KM, Nil, Qll and Til, are being regenerated.
- This preferred embodiment of the invention ensures a continuously flow of the solution being treated from one ion exchange material to the next ion exchange material.
- the pH of the resulting solution was raised to pH 3 using a 30% aqueous solution of NaOH (total amount of NaOH added: 20,600 mg).
- the solution was then contacted with the second anion exchange material, Marathon W.B.A., with a working temperature range of 0-60°C.
- the composition of the solution after contact with the second anion exchange material is shown in table 1.
