<div>To reduce the sulphur in the gas, we oxidyze it with good results, mainly.</div><div>But there are are 3 sites, with extremely high sulphur levels (70, 10 and 5 k ppm!) with no results. The methane levels are OK for two sites (55-60%) and bad for one (45). If we increase the air injection, the level drops, with a little increase of oxygen in all sites.</div>
<div><br></div><div>The digesters are lagoon type and they receive cow manure.</div><div><br></div><div>Any suggestion is appreciated.</div><div><br></div><div>Regards,<br clear="all"><div><br></div>-- <br>Arturo
