1/1

FEATURES

Optimally design pretreatment, feeding anddistributions of POME to digesters.

Innovative and efficient digester mixing.

Efficient biogas capture and distribution;

with built-in gas-holder.

Providing optimised operational and control

parameters based on long-term continuous

operations experience.

Incorporates efficient control, monitoring

and safety features, including excess gas

auto-flaring.

BENEFITS

High reliability and efficiency in methane

recovery, ~0.35 Nm3/kg COD.

Low power consumption, low O&M costs.

Regulated biogas output for direct use as boiler

fuel and power generation.

Ease of operations with simple and well planned

operational and maintenance schedule; no need

of system shut down for maintenance.

Minimised risks of digester failure; improvedtreated effluent quality for subsequent

facultative/aerobic treatment.

DIGESTER TECHNOLOGY:

The Anaerobic Digester Technology has been perfected over 20 years of continuous full scale operations.

The highly efficient anaerobic digestion design of our system allows maximum recovery of methane

possible from the optimally controlled operation of POME anaerobic digestion.
