Biogas for piggeries

Challenges for pig farms

Common issues
  • High COD/BOD
  • High Suspended Solids
  • High Phosphate levels
  • Odour problems from both ammonia and hydrogen sulphide
  • Generate more and better biogas
  • Control PH
  • Reduce Phosphate and BOD/COD
  • Avoid the use of a chemical scrubber
  • Reduce blockages from struvite
  • Safe product to handle

How does Biogas work ?

Anaerobic digestion is a natural process that converts organic matter present in wastewater sludge into biogas for electricity, as well as significantly reducing the contaminant load in treated water.

The energy produced from the biogas can be fed back into the grid or used in other parts of the production process, which represents a real opportunity to reduce energy costs.

ACTI-Mag, with its unique high surface area and high localised pH surface, is able to break down complex organic matter by hydrolysis into smaller units, which allows the biological system to convert the organic matter into biogas more quickly, and improve the quality.

Why to choose the right alkali ?

To control PH

Calix has developed ACTI-Mag, a concentrated, stabilised suspension of magnesium hydroxide, which is an inorganic compound that manages alkalinity and controls pH in anaerobic digestion of wastewater.

Dosing the wastewater streams with ACTI-Mag can reduce the amount of hydrogen sulphide produced. This offers the twin benefits of less odour and toxicity as well as increasing the biogas produced.

To reduce phosphate

There are two methods of removing phosphorus from wastewater: biological removal and chemical removal. Establishing and maintaining biological conditions for effective and continuous biological phosphorus removal can be quite challenging.

ACTI-Mag boosts this biological phosphate removal while at the same time capturing the excess phosphate within the sludge, which is beneficial for composting of solid waste.

To reduce BOD/COD

Boosting anaerobic digestion, ACTI-Mag supports bacteria and speeds up the breakdown of complex organic chains (including proteins, carbohydrates and lipids) into smaller units such as amino acids, sugars and long chain fatty acids.

The process reduces the rate-limiting step in the digestion process. This results in improving BOD/COD in the final effluent.

Queensland Anaerobic Trial

The system went from on being able take 75% waste stream to 100% of the waste stream

  • plus a reduction in BOD on the effluent
  • increased gas production from 400,000 m3 – 800,000 m3 greater than the increase in influent
