SulfaTreat is an economical and reliable method of removing hydrogen sulphide (H₂S), light mercaptan and other sulphur contaminant from a wide variety of air and gas vapours such as biogas / landfill gas.

Large units containing many tonnes of SulfaTreat operating on a lead/ lag basis available for high H2S challenges.

SulfaTreat provides consistently high removal efficiencies regardless of wide variations in the quantity of pollutants entering the system, temperature and pressure.

Small 322 litre drum units are often adequate for treating low volume applications, such as wet wells and pump stations. Blowers can be used and are preferred in high volume applications.

Single or multiple unit systems are used depending upon specific site needs. All are simple to use and require virtually no operator attention.

SulfaTreat media

Iron oxides that convert to ‘fools gold’
High % take up by weight for H2S
Non flammable media, very important
Water will not leach out chemicals
Some oxygen required for optimum performance
Very dense, so high take up by volume
Low pressure drop

System design

Stand alone vessel provide minimum capital cost
Lead/ lag vessels provides maximum economy
Final polishing after bioscrubber
Standby when biological systems not performing

Advantages

Very limited maintenance required
Ideal for unmanned sites
Specified performance immediately on start up
Indefinite media life in standby mode
No limit on inlet challenge
Immediate response to large changes in flow
Less than 1ppm outlet against any challenge
Accurate life prediction possible
