This document provides the fundamental principles and guidelines for industrial wastewater treatment technology pilot studies. It does not address laboratory research and development, study or testing of a given technology. It does not cover reuse applications or operations, such as irrigation. This document applies to a wide range of industrial water treatment systems for the purposes of reuse.

This document specifies a method for the determination of the dioxin‑like activity of water and wastewater by means of an AhR‑mediated reporter gene assay utilizing stably transfected mammalian cell line. This reporter gene assay is based on the activation of the mammalian AhR signalling pathway. This method is applicable to: —       drinking water; —       fresh water; —       groundwater…

Spectrometric method for the determination of anionic surfactants by measurement of the methylene blue index (MBAS) in aqueous media. Suitable for drinking water, surface water and waste water. Does apply for laboratory scale and technical large-scale waste-water treatment plants.

This document specifies a method for the detection, semi-quantitative and quantitative (MPN) enumeration of thermotolerant Campylobacter species. The method can be applied to all kinds of waters including: drinking water, ground water and well water, fresh, brackish and saline surface water, swimming pools, spa and hydrotherapy pools, recreational waters, agricultural waters and runoff,…

This document specifies a test method to determine the degree and rate of aerobic biodegradation of hides and skins of different animal origin, whether they are tanned or not, through the indirect determination of CO2 produced by the degradation of collagen. The test material is exposed to an inoculum (activated sludge from tannery wastewater) in an aqueous medium. If there is not a tannery…

ISO 13641-2:2003 specifies a screening method for assessing the potential toxicity of substances, mixtures, surface waters, groundwaters and wastewaters, effluents, sludges, or other environmental samples by determining the production of biogas (carbon dioxide and methane) from muds, sediments and other anaerobic environments with low biomass concentration. The growth rate of anaerobic bacteria…

This document specifies the general requirements for the in vitro amplification of nucleic acid sequences (DNA or RNA). This includes polymerase chain reaction (PCR)-based methods like quantitative PCR, qualitative PCR, reverse transcription-PCR and digital PCR. The minimum requirements laid down in this document are intended to ensure that comparable and reproducible results are obtained in…

ISO 20136:2017 specifies a test method to determine the degree and rate of aerobic biodegradation of hides and skins of different animal origin, whether they are tanned or not, through the indirect determination of CO2 produced by the degradation of collagen. The test material is exposed to an inoculum (activated sludge from tannery wastewater) in an aqueous medium. The conditions established in…

ISO 17294-2:2003 specifies a method for the determination of the elements aluminium, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, caesium, calcium, cerium, chromium, cobalt, copper, dysprosium, erbium, europium, gadolinium, gallium, germanium, gold, hafnium, holmium, indium, iridium, lanthanum, lead, lithium, lutetium, magnesium, manganese, molybdenum, neodymium, nickel,…

This document specifies a method for the determination of gross alpha and gross beta activity concentration for alpha- and beta-emitting radionuclides. Gross alpha and gross beta activity measurement is not intended to give an absolute determination of the activity concentration of all alpha and beta emitting radionuclides in a test sample, but is a screening analysis to ensure particular…
