Overview

This part of ISO 5667 should be read in conjunction with ISO 5667-1 and ISO 5667-15. The general terminology used is in accordance with the various parts of ISO 6107. Sampling and the determination of the physical and chemical properties of sludges and related solids are normally carried out for a specific purpose. The sampling methods given are suitable for general use but do not exclude modification in the light of any special factor known to the analyst receiving the samples or any operational reason dictating the need for sampling. Personnel taking samples shall be fully aware of safety requirements before sampling occurs. The importance of using a valid sampling technique cannot be overemphasized if the subsequent analysis is to be worthwhile. It is important that the personnel taking and analysing the sample be fully aware of its nature and the purpose for which the analysis is required before embarking on any work programme. Full cooperation with the laboratory analysing the samples ensures that the most effective application of the sampling occasion can be made. For example, the use of method-specific sample preservation techniques assists in the accurate determination of results. This part of ISO 5667 is applicable to sampling motivated by different objectives, some of which are to: a) provide data for the operation of activated sludge plants; b) provide data for the operation of sludge treatment facilities; c) determine the concentration of pollutants in wastewater sludges for disposal to landfill; d) test whether prescribed substance limits are contravened when sludge is used in agriculture; e) provide information on process control in potable and wastewater treatment, including: 1) addition or withdrawal of solids, 2) addition or withdrawal of liquid; f) provide information for legally enforceable aspects of the disposal of sewage and waterworks sludges; g) facilitate special investigations into the performance of new equipment and processes; h) optimize costs, for example, for the transport of sludges for treatment and/or disposal. The committee responsible for this standard is NA 119-01-03-04 UA "Schlamm und Sedimente" ("Sludge and sediments") at DIN.
