Digester Recirculation

Anaerobic Digester

Anaerobic digestion is the process by which organic
matter such as animal or food waste is broken down to
produce biogas and bio-fertilizer.
This process happens in the absence of oxygen in a
sealed, oxygen-free tank called anaerobic digester

Application : Digester Recirculation

PUMP: RGB 50 20AR 2C11 L600 3
PERFORMANCE: Flow 20m3/h – head 59 m
LIQUID: grape waste stillage

Pumps are used for liquid recirculation inside the digester in a biogas plant in a factory that produce wine and highly alcoholic products
The liquid contains 6-8% of fine particles that can be handled using pumps with semi-open impeller.

Impeller type: semi-open with wear plate and external adjustment.
Discharge sizes: from DN 32 to DN 125. 
Maximum working pressure: 16 bar 
Flow rate: up to 300 m3 /hr.
Differential head: up to 95 m.
High hydraulic efficiencies and low NPSH value (investment casting impellers).
