Child dataset exchanges identical to GLO dataset. Created to enable linking to regional markets (e.g. for electricity). Data quality indicators adjusted accordingly.
[This dataset was already contained in the ecoinvent database version 2. It was not individually updated during the transfer to ecoinvent version 3. Life Cycle Impact Assessment results may still have changed, as they are affected by changes in the supply chain, i.e. in other datasets. This dataset was generated following the ecoinvent quality guidelines for version 2. It may have been subject to central changes described in the ecoinvent version 3 change report (http://www.ecoinvent.org/database/ecoinvent-version-3/reports-of-changes/), and the results of the central updates were reviewed extensively. The changes added e.g. consistent water flows and other information throughout the database. The documentation of this dataset can be found in the ecoinvent reports of version 2, which are still available via the ecoinvent website. The change report linked above covers all central changes that were made during the conversion process.]
This dataset represents the production of ultrapure water by electrodeionization. The system includes the process with consumption of raw materials, energy, infrastructure, and land use, as well as the generation of emissions to air and water.As the tap water is not transported, no transports are considered for the raw materials. Transient or unstable operations like starting-up or shutting-down, are not included, but the production during stable operation conditions. Storage and transportation of the final product are also not included. It is assumed that the manufacturing plants are located in an urban/industrial area and consequently the emissions are categorised as emanating in a high population density area. The emissions into water are assumed to be emitted into rivers. Raw materials are modelled with a stoechiometric calculation. Emissions are calculated from the input properties. Infrastructure is estimated. Energy consumptions are calculated with literature data.
Production volume: 0.00444285714285714 kg
Included activities start: From the consumption of tap water at the factory as a starting material.
Included activities end: This activity ends with the production of ultrapure water including materials, energy uses, infrastructure and emissions. This activity does not include transportation, as the tap water is not transported.
Energy values: Undefined (default)
Geography: Child dataset exchanges identical to GLO dataset. Created to enable linking to regional markets (e.g. for electricity). Data quality indicators adjusted accordingly.
Technology level: 3 Current (default)
Technology: Ultrapurification of water can be carried out by different processes: ion exchange resins, mixed bed ion exchangers, homogeneous beds, membranes (reverse osmosis, ultrafiltration and nanofiltration) and electrodeionization. In this dataset the technology used is electrodeionization.
