The proprietary Lystek process involves a combination of heat, alkali, and high shear mixing to achieve effective lysis (breakdown) of the biological material in the biosolids. The resultant liquefied biosolid material provides a valuable nutrient-rich fertilizer product for the farm land application and optimization of wastewater treatment plant. Recycling of Lystek processed biosolids to anaerobic digesters enhances biogas / methane production by >40% and reduced biosolids generation by >30% requiring offsite disposal. The processed biosolids product is a readily available nutrient feedstock that improves organic utilization by the microbial population during the anaerobic digestion process.
