RECYCLING THE WASTE WATER OF THE PRODUCTION PLANT INTO PROCESS WATER – METAL AND SULPHATE CONTROL
You can take advantage of the adsorption phenomena and adsorbents as an additional purification technique, which allows to reuse waste water as process water.
The pre-treatment of the supply water of an RO plant improves the efficiency of the RO process. Adsorbents remove e.g. iron (Fe) and manganese (Mn) effectively from the supply water.
Adsorbents can also be used for the final treatment of the reject water of an RO plant, e.g. together with sulphate-removing methods.
RECLAMATION OF VALUABLE METALS IN A PRODUCTION PROCESS
It is worth reclaiming valuable metals as part of the production process: the chemical solubility balance restricts obtainability of the product in a traditional precipitation process. At the same time, the metal left in the solution can affect the quality of the resulting product.
Improve the effectiveness and economy of the process. Metal recovery after precipitation, and restoring the adsorbent or its regeneration solution into the acid leaching process improves the selectivity, the amount obtained and the purity of the recovered metals.
