High-performance removal of hydrogen sulfide from biogas! Introducing a system that is safe, low-cost, and has a high removal rate.
"THIOPAQ" is a biological desulfurization system that can achieve the removal of hydrogen sulfide from biogas with high efficiency and low cost. It is a highly reliable system with numerous operational records both domestically and internationally, capable of reusing the alkali generated during the decomposition of hydrogen sulfide, thereby reducing running costs. Thanks to its unique biological desulfurization method, it can provide stable treatment across a wide range of hydrogen sulfide concentrations (H2S concentrations of approximately 200 to 30,000 ppm). 【Features】 ■ A highly reliable and safe system - Over 20 years / more than 180 units delivered ■ Reduction in maintenance costs - Maintenance cost reduction through alkali regeneration ■ Flexibility to adapt to concentration fluctuations - Capable of operating in response to variations in wastewater treatment conditions *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Structure】 ■ Scrubber - By reacting biogas containing hydrogen sulfide with alkaline water, hydrogen sulfide in the biogas is absorbed into the alkaline water. ■ Biological Reaction Tank - Aeration is performed under weak alkaline conditions, and sulfides are oxidatively decomposed into sulfur and alkali by the action of sulfur-oxidizing bacteria. ■ Sulfur Separation Tank (Optional) - Sulfur extracted from the biological reaction tank is precipitated and collected. *For more details, please refer to the PDF materials or feel free to contact us.
