BKT's Enhanced Anaerobic Digestion (BEAD)

BEAD (Tomorrow Water's Enhanced Anaerobic Digestion Process) is an advanced process that treats biogas plant digester effluent. BEAD provides a solution for digestate treatment and enhances biogas production efficiency as well as increases stability

Why Use BEAD

 

SOLUTION FOR DIGESTATE TREATMENT

Nutrient disproportions prevent digester effluent from further biological treatment. Likewise, emerging discharge limitations prevent direct land application. The only viable option is to physically remove the contaminants from the wastewater (digestate).

INCREASED BIOGAS PRODUCTION

Typical digester effluent contains a significant amount of recoverable microbes and in some cases unused carbon. Tomorrow Water's anti-fouling filtration system, FMX, concentrates the biomass and returns it to the reactor improving relative conversion and efficiency.

STABLE DIGESTER OPERATION

Like any biological process, anaerobic digesters are sensitive to the inlet conditions. By operating in recycle mode, FMX lessens the severity of fluctuations in the feed material. Added stability also contributes to reactor efficiency by reducing downtime and subsequent reseeding.
