JH Stålindustri has made several hygienic tanks where the product must be above 72°C.

Without this, we have special heat exchangers for heating and cooling of the sludge.

The new process of hydrolysis can increase the biogas production by further 20 to 30% compared to a standard plant. Hydrolysis temperature, which is between 70 and 80°C will reduce operating costs, including sludge reduction without fertilizer value is changed.
