PD CEN/TS 13714:2013CEN/TS 13714:2013 (E) 5 Introduction The purpose of this Tec

22、hnical Specification is to outline the management of sludges both upstream and downstream of the treatment process to ensure that it is suitable for the outlets available. Sludge is the inevitable residue of treating raw potable water and municipal and industrial wastewaters. This Technical Specific

23、ation refers to all types of sludge covered by CEN/TC 308 including sludges from treating industrial wastewater similar to urban wastewater and from water supply treatment work plants. In considering the likely quality of sludges, it should be remembered that municipal wastewater sludges are compose

24、d of materials that have already been disposed of and are consequently likely to be more variable than many industrial sludges that arise from sourced materials or water treatment sludges arising from surface water or groundwater. The quality of the sludge should match the requirements of the outlet

25、s whether that be to land, thermal processing or as a last resort landfill. As a general rule a high quality sludge is likely to be acceptable to a large range of outlets giving greater operational flexibility. High quality sludges are likely to be suitable for those outlets associated with maximum

26、sustainability and minimum environmental pollution. The management of sludges will become increasingly more complex as environmental standards become more stringent and if outlets become more constrained by legislation and public attitudes. Sludge quality is central to the development of good practi

27、ce for sludge production in relation to its destination (use or disposal). Sludge quality depends on the composition of the upstream materials and the type of treatment including post treatment storage. Sludge quality can be characterised by its different properties; biological, chemical and physica

28、l: a) biological properties include the microbiological stability of the organic matter in the sludge, odour and hygienic characteristics; b) chemical properties include: 1) content of potentially toxic substances (PTSs) which include inorganic (metals, metalloids, and other minerals), and organic p

29、ollutants; 2) concentrations and form (availability) of plant nutrients and the main components of the sludge; c) physical properties include whether liquid, semi-solid (pasty-like) or solid, and aesthetic factors associated for instance with removal of unsightly debris by effective screening. Calor

30、ific value is a quality criterion if the sludge is to be incinerated or used as a fuel. Other physical properties include, thickenability and dewaterability. The consistency of these different properties is a critical aspect of the sludge quality and of the ability to determine its end destination (

31、use or disposal). Standard methods should be used where these are available to measure the quality parameters of sludge. There is a continuing need to develop a full set of standardised and harmonised methods which the manager and operator can use to evaluate the quality of sludge for treatment proc

32、ess design and operational purposes. This Technical Specification considers the management of sludges against the waste hierarchy, the management of sludge quality and an option evaluation process to determine the options available.

This Technical Specification is applicable for sludges from: storm water handling; night soil; urban wastewater collecting systems; urban wastewater treatment plants;

35、 treating industrial wastewater similar to urban wastewater (as defined in Directive 91/271/EC 1); water supply treatment plants; but excluding hazardous sludges from industry. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are in

40、ental Quality Standards PTS: Potentially Toxic Substance 4 Waste hierarchy 4.1 General In order that the management of waste be conducted in an increasingly sustainable manner, the EU encourages a waste hierarchy as a framework by which Member States should develop their strategy for waste managemen

41、t (EU Directive 75/442/EEC (see 2) as amended by 91/156/EEC (see 3). Figure 2 The waste hierarchy Including sludges This hierarchy encourages: a) firstly, the prevention or reduction of waste production and its harmfulness, in particular by: 1) development and implementation of clean technologies mo

42、re sparing in their use of natural resources; 2) technical development and marketing of products designed so as to make no contribution or to make the smallest possible contribution, by the nature of their manufacture, use or final disposal, to increasing the amount or harmfulness of waste and pollu

43、tion hazards; 3) development of appropriate techniques for the final disposal of dangerous substances contained in waste destined for recovery; b) secondly, the best possible use of waste: 1) recovery of waste by means of recycling, re-use or reclamation or any other process with a view to extractin

44、g secondary raw materials; 2) or the use of waste as a source of energy. The hierarchy places disposal as the last management choice. PD CEN/TS 13714:2013CEN/TS 13714:2013 (E) 9 Four of the stages within the hierarchy can be applied to sludges, namely reduction, recycling, recovery and disposal. Obv

45、iously, the latter is the least desirable and efforts should be made to minimise the proportion of sludge which is disposed of, by the adoption of clean technologies, recycling and recovery strategies. The waste hierarchy can be applied equally to activities upstream of the sludge production process

46、 and to the processes employed within the treatment process. These are discussed separately below. In considering what management options should be selected, all stages in the sequence of sludge production and its ultimate fate should be scrutinised. 4.2 Context The overall objective of a sludge man

47、agement strategy should be to find outlets for the sludge which are safe, environmentally acceptable (carbon foot print), secure and economic. The availability of outlets (see Clause 8) determines how sludge should be treated. In order to do this, it is important to address quality (Clause 5) and ma

48、nagement processes (Clause 6) and operational practices (Clause 7). 5 Management of sludge quality - Upstream processes 5.1 General The significant difference between municipal sludges and industrial sludges and to a certain extent water treatment sludges is the degree and complexity of control over

49、 the inputs. Industrial sludges usually arise from the processing of sourced materials and control over their content and consequently the quality of sludge can often be made by analysis of the materials and in many cases by the imposition of quality standards on them. This may not always be possible for instance in the amount of bacteriocides and fungicides in paper waste collected for recycling which could vary from batch to batch. River waters can carry a range of pollutants which could enter the sludge and operators should be aware
