DOSFOLAT® XS, fast acting variant of the stabilised folic acid micronutrient DOSFOLAT®, accelerates biological treatment of municipal, industrial and mixed wastewater streams. Especially appropriate for use in applications with fat, oil and grease and where improved process nitrification is desired, DOSFOLAT® XS continues to provide the beneficial effects that are associated with folic acid treatment. These effects include control of filamentous bulking, pin floc, dispersed growth and foam problems associated with activated sludge separation; return to normal settling with stable, low SVI and low sludge blankets; reduced sludge production through more complete digestion and improved sludge characteristics; and fast start up and improved stability in response to flow, load, temperature and toxic shocks. Increased plant efficiency, resilience and stability is achieved naturally by the stimulating effect of folic acid on biomass growth and metabolism.

Folic acid, a B complex vitamin, is essential for the growth and metabolism of all cells. Its action increases the variety, number and activity of microorganisms in secondary wastewater treatment.

Results with DOSFOLAT® XS:

  • Accelerated treatment/faster additive response.

  • Effective secondary treatment of fat, oil and grease

  • Filament and SVI control

  • Enhanced nitrification

  • Reduced waste sludge/improved sludge characteristics

Plant trials can now generate results in 28 days because DOSFLAT® XS acts fast. The new test regimen requires 14 days treatment at 0.7 ppm and 14 days at 0.35 ppm. Traditional test treatment based on sludge age and influent strength, and running 60 - 90 days, may still be recommended where high influent loading or other factors dictate. Please see the DOSFOLAT® Handbook for a full treatment of application instructions.

  • The question of which plant trial is appropriate for your application should be discussed with your Regional Representative (please goto the SALES&SUPPORT section)or contact the home office at (800) 366-9141 or via email .
