SULPHUR control

Our uniquely formulated raw materials reduce the concentration of hydrogen sulphide in biogas, thereby offering the following important benefits:

1. Helping to prevent the inhibition of the biological process and optimising iron
concentrations in the fermenter system.

2. Helping to prevent any damage to the mechanical components of the CHP as
well as improving the biogas quality in biomethane systems.

DE-SULFO-RED -Highly effective, economical source of iron for regular daily use and for digesters with longer retention times. Very small particle size increases speed of action and availability of iron.

  • High iron content
  • Low heavy metal content
  • Smaller particle size than is usual for this iron source
  • Non-toxic
  • Non-corrosive
  • 25kg bags on 1000kg pallets

METHO S - Used to quickly reduce digester Sulphur levels where inhibition may be a problem, or in digesters with a short retention time.

  • Powdery ferric hydroxide based reagent
  • Very fast acting
  • Highly reactive
  • Fine particle size
  • Non-toxic
  • Non-corrosive
  • 20kg bags on 1000kg pallets

METHO FILTER - A range of products for filtering the biogas and removing hydrogen sulphide and other naturally-occurring impurities (silicates, oxalates, etc.)

  • Prevents damage to the CHP’s mechanical components.

  • Extends oil change intervals in the CHP

  • Scope of use: Can be used in all ordinary activated charcoal absorbers.

  • 2-8 mm and 5-25 mm pellets with a filtering capacity +20% higher than normal activated charcoal filters

  • 5-25 mm pellets to form a filtering bed at the filter inlet (approx. 30%)

  • 2-8 mm pellets with high filtering capacity (approx. 70%)

  • 30kg bags on 510kg pallets or 550kg bulk bags
