Description
This is a market activity representing a mixed treatment. In the case of products requiring treatment, the market mix is provided by activities that treat products within the geographic area defined by the market, and they supply the activities requiring product treatment because they generate waste (recyclable) or waste (non-recyclable) as by-products in unspecified processes (represented in the system model as negative inputs). Where relevant, transportation to treatment facilities or losses are also accounted for within such markets.
This is the market for 'domestic wastewater' in the Northwestern region of China, which includes Shaanxi, Gansu, Qinghai, Ningxia, and Xinjiang. The dataset covers transportation from producers to consumers of the product within this geographic region.
Process Description
"Domestic wastewater" is wastewater generated from residential sources. It originates from a wide range of residential, industrial, and commercial activities. In the HIQ database, the treatment options for this wastewater include: wastewater treatment plants.
Domestic wastewater is produced by common transformation activities. It is generally considered waste (non-recyclable) and requires further treatment.
Domestic wastewater can be modeled at two levels: treatment activities and market activities. The former refers to specific technologies or technology mixes for treating this waste, while the latter represents a mixture of treatment processes. Two modeling approaches are available for users to choose flexibly. When making specific process assumptions about wastewater treatment, users may select specific technology treatment activities. Wastewater collection and transport are considered in their respective market activities involving sewer infrastructure; the conveyance of wastewater through sewer grates before entering the treatment plant leads to losses. Direct emissions resulting from these losses are accounted for within the market activities. These losses are region-specific, so users are encouraged to review the regional modeling assumptions.
