The March 2014 edition of SCOPE includes among other articles on:
Phosphate recovery likely to be made obligatory
The revision of the Swiss federal ordinance on waste treatment OTD.RS.814.600, currently open to comment from local authorities, includes the obligation to recover phosphorus from sewage sludge and animal meat and bone meal.
Anammox plus struvite recovery
Biological ANAMMOX treatment of sludge dewatering centrate (see SCOPE Newsletter n° 89) was combined with struvite precipitation to assess a possible combined process for abatement of ammonia-N and soluble P with phosphorus recovery for recycling. This thesis has interest as a first assessment of the potential of combining ANAMMOX denitrification with struvite recovery to remove nutrients and recycle phosphorus from sludge dewatering liquors.
