Fermentation systems, waste water treatments plants and manure processing companies often have to stop production due to foam formation, which can reach heights of several metres. Did you know that foam formation can reduce efficiency by up to 30%? In addition, foam can cause the pressure in an enclosed space to rise to such an extent that flexible roofing can no longer cope. Such roofing can tear, allowing gas to escape uncontrollably. Fortunately, Van Meeuwen has a number of excellent solutions for this situation. Our biologically-responsible anti-foam additives can improve the efficiency of your biogas production by as much as 30%. We also supply biological anti-foams for manure processing which are used for the de-nitrification of manure pits.
