Digester ASTM Standards

General This Code applies to the installation of systems for the production, handling, storage, and utilization of digester gas in newly constructed wastewater treatment plants, as well as additions to, and the upgrading of, existing systems. This Code applies to the installation of systems...

This document provides guidelines and describes quality control and testing procedures for application of either stainless steel or nickel-base corrosion resistant weld metal overlay (hereafter referred to as CRO) on internal surfaces in continuous digesters, impregnation vessels, and batch...

1.1 This test method is primarily for the determination of speciated volatile sulfur-containing compounds in high methane content gaseous fuels such as natural gas. It has been successfully applied to other types of gaseous samples, including air, digester, landfill, and refinery fuel gas....

5.1 The chemical analysis of sediments, collected from such locations as streams, rivers, lakes, and oceans can provide information of environmental significance. 5.2 These practices can be used with either suspended sediment (material actively transported by water) or bed sediment (material...

The chemical analysis of sediments, collected from such locations as streams, rivers, lakes, and oceans can provide information of environmental significance. These practices can be used with either suspended sediment (material actively transported by water) or bed sediment (material temporarily at...

These practices cover the digestion of ores and related metallurgical materials, such as mine soil, waste rock and tailings, for subsequent determination of acid-extractable contents of certain elements by such solution analytical techniques as atomic absorption spectrometry (AAS), atomic emission...

This test method is applicable for the analysis total nitrogen (organic nitrogen + ammonia-N + nitrate-N + nitrite-N) as nitrate and total phosphorus as orthophosphate in unfiltered water samples by alkaline persulfate digestion followed by ion chromatography (IC). Total Kjeldahl nitrogen (TKN) is...

This standard specifies hash algorithms that can be used to generate digests of messages. The digests are used to detect whether messages have been changed since the digests were generated.

This test method is intended for use with extracted or digested samples that were collected during the assessment, management, or abatement of lead hazards from buildings, structures, or other locations. This test method covers the lead analysis of sample extracts or digestates (for example,...

This test method covers the determination of the degree and rate of anaerobic biodegradation of plastic materials in high-solids anaerobic conditions. The test materials are exposed to a methanogenic inoculum derived from anaerobic digesters operating only on pretreated household waste. The...

1.1 This test method determines the degree and rate of anaerobic biodegradation of synthetic plastic materials (including formulation additives) on exposure to anaerobic-digester municipal sewage sludge from a waste-water plant, under laboratory conditions. 1.2 This test method is designed...

This practice covers basic principles and operating procedures for testing water resistance of coatings using controlled condensation. Condensation is produced by exposing one surface of a coated specimen to a heated, saturated mixture of air and water vapor, while the reverse side of the specimen...

5.1 This test method allows the simultaneous determination of total nitrogen and total phosphorous from one sample digestion step. 5.2 This test method measures oxidized ammonia and organic nitrogen (as nitrate) and soluble nitrate simultaneously. By subtracting the nitrate + nitrite value from a...
