Description
The Coal Authority operate over 75 minewater treatment schemes that remove contaminating metals from mine water prior to the treated water being discharge into a receiving watercourse.
Schemes range from complex process engineering plants, through pumped wet wells and boreholes/mineshafts, to totally natural (passive) schemes without a power source.
A number of sites require the addition of pH correcting or oxidising reagents. Flow rates range from circa 5 litres/sec to 400 litres/sec. A standard pumped treatment scheme utilizes 32 digital inputs, 8 analogue inputs and 8 digital outputs.
The majority of treatment schemes comprise of aeration cascades, settlement ponds and reed beds. All schemes are subject to regulatory consents and licenses.
The Coal Authority is now considering the potential of High density Sludge (HDS) plants in treating mine water (acidic and alkaline) as well as the potential benefits that can be achieved with a sludge management system.
From a Coal Authority perspective, the sludge generated (principally ochre) would be predominantly iron oxy-hydroxides with other metal hydroxides.
The characteristics of the resultant ochre from a HDS plant are a consideration for the Coal Authority, as potential markets for ochre may arise in the future.
Areas of interest of the Coal Authority include:
• Sample collection and preparation
• Laboratory testing
• Pilot testing (off and on site)
• Analytical Capabilities
• Plant conceptual design
• Whole life costs
We would like to invite interested companies to meet with us at our Mansfield office during September / October 2018 to better understand our requirements and offer suggestions on how we might fulfil our objectives through a future tender process.
Once the Coal Authority has assessed interest, it will advise on if meetings are to be conducted on an individual basis or as a group with multiple companies present.
If you have any queries please express your interest by contacting peterkobryn@coal.gov.uk no later than 18 September 2018
