Description

The project owner S-Metalltech 98 Ltd produces different absorber materials which are suitable for filter out arsenic, fluorine and phosphorus from drinking- and industrial waters. During the production, high DMSO -containing hazardous wastewater is arisen - daily 1 m3, which is currently collected and incinerated in incineration plant. The aims of the project are to reduce the hazardous waste produced in the production of the absorber, and to recycle the valuable DMSO solvents and other chemical components. The base of the technological solution developed by the project is distillation and/or evaporation. The contaminated DMSO – water can be separated by vacuum distillation together with pre and post treatments in several steps. The result of distillation is distilled water and industrial-grade DMSO and other chemical components which are able to be recycled later. The outcomes of the development are nearly 100% decrease of pollutant emission and significant water saving. Further outcomes the technical, environmental and economic sustainability of the factory in short term and the better competitiveness of the company in long term.
