PD CEN/TR 13983 indicates sludge utilization within reclamation programs of disturbed land.
PD CEN/TR 13983 applies to sludges described in the scope of CEN/TC 308; for example:
Note: Because of the wide range of reclamation sites where sludge use as a soil ameliorate or source of plant nutrients is beneficial, and the different potential final uses of these sites, recommendations for application should be considered on a site-by-site basis. It is far beyond the scope of these guidelines to describe all the possible situations and the individual ways in which sludge could be used. The aim is to address, in a general qualitative way, the key issues which will determine in each particular case whether, how much, and which type of sludge can be used.
Planning considerations (clause 5) are emphasized because a general scheme can be adopted as a common procedure in nearly all situations.
BS EN 14702 on the characterization of sludges is useful for entities dealing with:
In wastewater treatment plants, sludge thickening occurs in the lower layers of clarifiers and separate thickening tanks. Several parameters have been developed to obtain a quantitative measure of the settleability of sludge.
PD CEN/TR 13983 provides methods and procedures for efficient and cost-effective utilization of sludge land.
PD CEN/TR 13983 characterizes practices and methods that can be easily performed and has widespread use in routine process control for sludge quality comparison and reclamation.
PD CEN/TR 13983 gives you the procedure for the use of indexes for sizing/optimizing decanters and talks about the care with which they should be handled.
PD CEN/TR 13983 provides you with the measures for determining the treatment of sludge, that can help you in landfilling of sludge and enables sludge treatment as the lowest cost for its volume reduction.
