Biogas energy solutions

CSTR Plus

Turn palm oil mill effluent into a biogas resource.

Palm oil mill effluent

A closer look at the process.

CSTR Plus is part of BIOZOOM’s anaerobic digestion portfolio for palm oil mill effluent (POME). The system brings mixing and continuous discharge together within a continuous digestion process.

Reactor sizing, feed preparation and operating conditions are selected around the feedstock and intended use of the biogas. Share your POME analysis and site requirements to begin the discussion.

Two cylindrical CSTR digestion tanks with exterior access stairs and connecting pipework.

Design data

Key figures

  • >35 m³ biogas / m³ POME
  • CH₄ >60%
  • >5 kg COD/m³·d
  • About half the volume of a lagoon
  • Continuous sludge discharge

Source: BIOZOOM design data. Actual performance depends on feedstock and operating conditions.

POME applications

A digestion route for palm oil mill effluent.

Uniform mixing

Mixing supports contact between the feedstock and the biological process.

Continuous discharge

A continuous operating arrangement for the digestion system.

A useful starting point

Bring your project into focus.

  1. POME flow, solids content and available COD analysis.
  2. Feed temperature, operating schedule and existing treatment.
  3. Your intended use of the biogas and available site area.
