The Hulshof Royal Dutch Tanneries (since 1876) is one of the largest European producers of high quality upholstery leather. The leather is both produced and specially finished at the Royal Dutch Tannery.
Hulshof outsourced their wastewater treatment to Waterstromen BV in 2001. A new effluent treatment plant was designed and built by Paques in close cooperation with Waterstromen BV. Main drivers were reduction solid waste, removal of sulphate, nitrogen and metals and the production of biogas.
The new plant consists of anaerobic treatment of sludge and wastewater (BIOPAQ IC) combined with biological sulphide oxidation (SULFATEQ) and the Paques' process for nitrogen removal (ANAMMOX). COD, sulphate, sulphide, chromium and nitrogen are all removed to low levels. The amount of solid waste was significantly reduced compared to the earlier physical/chemical treatment. The biogas generated in the treatment process is used to produce electricity.
• This project won 'Best LIFE-Environment projects 2006-2007 award'.
• Hulshof is a role model for European regulations (IPPC) for tanneries (Best Available Techniques)
