ECONOX 20 Kills Odour Complaints At Berisfords

As a result of local odour complaints, a new sulphide discharge consent was imposed on Berisfords Ribbons. Yara Industrial was requested to conduct a trial using ECONOX 20 liquid sodium permanganate to control sulphide levels at the effluent discharge point.

To comply with occupational exposure standards, hydrogen sulphide levels need to be maintained below 5ppm. However, odour complaints can result at very low levels and it is often necessary to maintain hydrogen sulphide levels below 1 ppm.

Without ECONOX 20 dosing, the peak hydrogen sulphide values ranged from 8 to 15 ppm. These levels have the potential to trigger odour complaints from local residents.
With an automated ECONOX 20 dose system, the peak hydrogen sulphide levels were drastically reduced to around 1ppm. These peaks are much less likely to trigger odour complaints.

"We are very happy to work with Yara Industrial. Yara Industrial and all their employees have been especially helpful in their specialised fields and Berisfords Ribbons would recommend Yara to any other company that has effluent problems with hydrogen sulphide levels, especially companies that deal with dyes" Many thanks K.Sutton
