Water and gas treatment products

BioSO4-biopolymers are produced with a zero-waste technology and sourced from the food industry. Together with our customers, BioSO4 has already solved a variety of  environmental challenges, namely involving heavy metal concentrations.  In partnership with our clients, we pursue customized sustainable solutions for water purification. In addition to high-quality products, we offer knowledge and expertise concerning the application in question, product development in response to changing circumstances, as well as cost-efficient global logistics.

A significant advantage of our water treatment method over other systems is the capacity for highly selective sulphur and metal recovery (cobalt, copper, lead, nickel, scandium, zinc etc.) from process and wastewater. We have also developed highly selective adsorbents for the nitrogen and phosphate removal from both waters and gas. 

Our technology can be implemented within processes and flowsheets having continuous recovering modules or easy installations of passive filter solutions. The standard filter sizes are between 0,8 m3 to 20 m3. The technology is modified and customized to meet the specific process requirements of all our customers.

We have also developed a quick and an accurate method for analyzing the concentrations of various xanthates (SEX, SIBX, PAX, …) in commercial products as well as from environmental residues. The quality and quantity of each xanthate phase, residues and potential impurities are analyzed for each delivered product batch. Our high-purity xanthates and analytical methods allow the dosage of xanthates to be minimized. This method can also be used to investigate the quality of many other mining reagents.
