The cost of disposal of oil industry waste process water has become significantly high as to warrant alternatives to direct disposal to the foul sewer. In UK the water industry charges industrial users on a variable scale depending upon the “dirtiness” of the water for disposal. This is an extension of the Polluter Pays principal.
The oil extraction industry based in Aberdeen has recognised the importance of pre-treatment of process water prior to disposal to the municipal sewer. As such ClearEarth Ltd was invited to design a simple system to treat waste water arising from the on-shore processing of oily slops.
