Description
This is a market activity, representing a mixed treatment. In the case of products that require treatment, the market mix is supplied by activities that treat the product in the geographical location defined by the market, and they supply activities that require the product to be treated, as they generate it as waste (recyclable)/waste (non-recyclable) in an unspecified process (presented as a negative input in the system model). Where relevant, transport to the treatment facility or losses are also included in this type of market.\n\nThis is the market for "domestic sewage" in Xining, Qinghai Province. It covers the transport from producer to the consumer of this product within this geographical region.
Process Description
"Domestic wastewater" is wastewater generated from residential sources. It comes from a wide range of residential, industrial and commercial activities. In the HIQ database, the treatment options for this wastewater include: wastewater treatment plant.
Domestic wastewater is produced from common conversion activities. Generally treated as waste (not recyclable) and requiring further processing.
Domestic wastewater can be modeled at two levels: treatment activities and market activities. The former refers to the specific technology/mix of technologies used to treat that waste, while the latter represents mixed processing. Two modeling approaches provide the user with the flexibility to select technology-specific treatment activities when specific process assumptions are made for wastewater treatment.
The collection and transportation of wastewater consider the use of sewer infrastructure in their respective market activities; transporting wastewater through sewer grids results in losses before the wastewater enters the wastewater treatment plant. Direct emissions due to these losses are taken into account in market activities. Losses are region-specific, so users are encouraged to check regional modeling assumptions.
