Spiraltec GmbH is the first company in the world to successfully develop wound membrane modules for the membrane separation process of diffusion dialysis and to realize the countercurrent principle. This environmentally friendly dialysis process is used, for example, in the removal of metals and the recovery of free acids or free alkalis from used treatment baths. Examples of industries in which our modules can be used include surface technology, the printed circuit board industry and the semiconductor industry.
The WD membrane spiral wound module from Spiraltec GmbH is used, for example, for continuous and stationary wastewater treatment. It enables the highest recycling rates of free acids and free alkalis. These recovered raw materials can be reused at the highest value level. In addition, the volume of wastewater is reduced by up to 70 % compared to other recycling processes. This also makes subsequent disposal processes more energy and cost efficient and makes it easier to comply with limit values and environmental guidelines.
Our membrane spiral wound modules are available in various capacities and with different special membranes and can be combined into one large module in different systems. Thanks to this modular design, they are flexibly configurable, easily scalable and cost-effective to integrate. This design also enables high process availability and short maintenance times.
Diffusion dialysis in general:
Diffusion dialysis is a general membrane separation process that is used, for example, in ultrafiltration, reverse osmosis or blood dialysis.
Basically, the process is based on the flow of two different fluids through two channels that are separated by a semi-permeable membrane. In a simplified process, substances are transported from concentrated to diluted fluids until the difference in concentration is equalized.
Spiraltec specializes in individual requests and is now represented worldwide with its coiled modules for diffusion dialysis.
