At the end of the first conference day we kindly invite you to use the relaxed and informal atmosphere for in-depth conversations with other participants and speakers.

IV. Sludge Incineration and Plant Concepts

P-Recovery from Sludge

• Current state of P-recovery from sludge
• Legislation and technology challenges
• Developments in the Netherlands and Germany

M.Sc. Renske Verhulst, Nutrient Platform, Netherlands and Dr. Daniel Frank, Managing Director, Deutsche Phosphor-Plattform e.V., Germany

Low Temperature Belt Drying: An efficient, safe and environmentallyfriendly Solution when well done!

• Energy efficiency: Enhanced waste heat recovery
• Intrinsically safe: Out of ATEX application
• Odour management: Not only the dryer process air
• Application field: Examples of a broad range of applications

Lynne Bouchy, International Business Development, Suez, Spain

Electro-Dewatering (EDW) of Sludge: A technological Solution to turn a Problem into an Opportunity

• Mechanical sludge dewatering achieves maximum dry solid content of 30%
• EDW: Dry solid content up to 45%, compatible with monoincineration without prior thermal drying
• EDW: Effective on aerobically stabilized sludge 
• High energy consumption of EDW is counterbalanced by lower costs in transport and disposal
