We are highlighting our SigmaDAF USA line of Dissolved Air Flotation (DAF), Membrane Bioreactors (MBR), and Filter Press systems at WEFTEC 2025 in Chicago, IL, from September 29th to October 1st.  Visit booth #3450 to learn about our turnkey and compact systems for efficient wastewater treatment.

The SigmaDAF USA line of DAF systems treats wastewater from a wide range of industries and applications, including pretreatment, biomass separation, and sludge thickening. Our modular and turnkey physical-chemical designs manage a wide range of flowrates and solids loads. In-house manufacturing and wet testing guarantee reliability and durability.

The compact and self-contained MBR systems make them true plug-and-play units. These systems contain all the necessary instruments and include an enclosed control room, making them easy to install and operate. The modular design allows for easy installation and growth by adding units as flows increase.

Together, the DAF and MBR systems remove and reduce TSS, O&G, BOD, COD, TKN, ammonia, and more. With the removal capabilities, these systems serve many industries, including municipal, food production, oil and gas, animal processing, fruit and vegetable processing, textiles, cosmetics, and more.

SigmaDAF USA designs and manufactures filter presses for sludge dewatering. All our filter presses are side transfer and offer different levels of automation: manual, semi-automatic, and fully automatic equipment. Our filter presses guarantee excellent performance in all types of industrial processes and wastewater treatment.
