17、available. Sludge is the inevitable residue of treating raw potable water and municipal and industrial wastewaters. The Technical Report 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 treatme

18、nt work plants. In considering the likely quality of sludges it should be remembered that municipal wastewater sludges are composed 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

19、treatment sludges arising from surface water or groundwater. The quality of the sludge should match the requirements of the outlets whether that be to land, thermal processing or as a last resort landfill. As a general rule a sludge of high quality is likely to be acceptable to a large range of outl

20、ets giving greater operational flexibility. High quality sludges are likely to be suitable for those outlets associated with maximum sustainability and minimum environmental pollution. The management of sludges will become increasingly more complex as environmental standards become more stringent an

21、d if outlets become more constrained by legislation and public attitudes. Sludge quality is central to the development of good practice 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 treatmen

22、t including post treatment storage. Sludge quality can be characterised by its different properties; biological, chemical and physical: biological properties include the microbiological stability of the organic matter in the sludge, odour and hygienic characteristics; chemical properties include: co

23、ntent of potentially toxic substances (PTSs) which include inorganic (metals, metalloids, and other minerals), and organic pollutants; concentrations and form (availability) of plant nutrients and the main components of the sludge; physical properties include whether liquid, semi-solid (pasty-like)

24、or solid, and aesthetic factors associated for instance with removal of unsightly debris by effective screening. Calorific 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

25、 different properties is a critical aspect of the sludge quality and of the ability to determine its end destination (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 standardi

26、sed and harmonised methods which the manager and operator can use to evaluate the quality of sludge for treatment process design and operational purposes. This Technical Report considers the management of sludges against the waste hierarchy, the management of sludge quality and an option evaluation

27、process to determine the options available.

28、 inputs and treatment and gives a strategic evaluation of recovery, recycling and disposal options for sludge according to its properties and the availability of outlets. This report is applicable for sludges from: storm water handling; night soil; urban wastewater collecting systems; urban wastewat

29、er treatment plants; 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 referenced documents are indispensable for the application of this

35、velop their strategy for waste management (EU Directive 75/442/EEC (see 2) as amended by 91/156/EEC (see 3). Figure 1 The waste hierarchy Including sludges This hierarchy encourages: a) firstly, the prevention or reduction of waste production and its harmfulness, in particular by: development and im

36、plementation of clean technologies more sparing in their use of natural resources; 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

37、 or harmfulness of waste and pollution hazards; development of appropriate techniques for the final disposal of dangerous substances contained in waste destined for recovery; Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 08/12/2010 07:37, Uncontrolled Copy, (c) BSIPD CEN/TR 13714:2010CEN/TR

38、 13714:2010 (E) 7 b) secondly, the best possible use of waste: recovery of waste by means of recycling, re-use or reclamation or any other process with a view to extracting secondary raw materials; or the use of waste as a source of energy. The hierarchy places disposal as the last management choice

39、. Four of the stages within the hierarchy can be applied to sludges, namely reduction, recycling, recovery and disposal. Obviously, 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

40、 and recovery strategies. The waste hierarchy can be applied equally to activities upstream of the sludge production process 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

41、sequence of sludge production and its ultimate fate should be scrutinised. 4.2 Context The overall objective of a sludge management 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

42、Clause 8) determines how sludge should be treated. In order to do this, it is important to address quality (Clause 5) and management processes (Clause 6) and operational practices (Clause 7). 5 Management of sludge quality - Upstream processes 5.1 General The significant difference between municipal

43、 sludges and industrial sludges and to a certain extent water treatment sludges is the degree and complexity of control over the inputs. Industrial sludges usually arise from the processing of sourced materials and control over their content and consequently on the quality of sludge can often be mad

44、e 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 p

45、ollutants which could enter the sludge and operators should be aware of the potential pollutants that could enter the river upstream. 5.2 Municipal wastewater sludges For municipal wastewater sludges strict limits should be imposed on industrial and commercial discharges to the sewer so that the slu

46、dge produced from wastewater is clean or as free as possible of contaminants of industrial origin. Industrial point sources of contaminants discharging to the sewer should be identified and restricted or stopped. Key factors are careful discharge consent settings (see below) monitoring and inspectio

47、n backed by enforcement. Quality assurance in support of the consent requires adequate sampling to check compliance. The extent of sampling of effluent from industrial premises should be decided on a risk assessment basis taking account for instance of size of operation and quantity of chemicals in

48、use. The “polluter pays“ principle should be used to oblige industries failing to produce acceptable effluents to investigate and implement remedial measures. This may entail a change in the production process or the installation on the industrial premises of effluent treatment plant. Often the cost

49、 of this is offset by reduced Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 08/12/2010 07:37, Uncontrolled Copy, (c) BSIPD CEN/TR 13714:2010CEN/TR 13714:2010 (E) 8 payments for effluent discharge and the recovery and reuse of valuable chemicals that would otherwise have been discharged to the sewer. Experience has shown that by progressively identifying and controlling point source discharges, the quality of sludge can be substantially improved by reducing i
