Abstract
A local sewage processing unit is provided that receives sewage from a local source of sewage, extracts water from the received sewage that is suitable for re-use and includes a pump that is configured to pump sewage from a receiving section of the local sewage processing unit into a pressure sewer network, as required.
Claims21
A local sewage processing unit comprising:
- a receiving section configured to receive sewage from a local source of sewage, wherein the receiving section includes a holding tank, configured to provide initial anaerobic processing of the sewage;
- a processing section, configured to extract water from the sewage received at the receiving section such that the extracted water is suitable for re-use;
- and
- a pump, configured to pump residual sewage from the receiving section into a sewer network that transports the residual sewage to a central sewage treatment plant.
1 more element
A sewage treatment system, comprising:
- a plurality of local sewage processing units, wherein each local sewage processing unit comprises:
- a receiving section configured to receive sewage from a local source of sewage, wherein the receiving section includes a holding tank, configured to provide initial anaerobic processing of the sewage;
- a processing section, configured to extract water from the sewage received at the receiving section such that the extracted water is suitable for re-use;
- and
- a pump, configured to pump residual sewage from the receiving section into a sewer network;
- wherein each local sewage processing unit is configured to process sewage received from a respective local source of sewage and extract water suitable for re-use;
- a sewer network;
- and
- a central sewage treatment plant;
- wherein each of the local sewage processing units is configured to pump sewage from the receiving section into the sewer network;
- and
- the central sewage treatment plant is configured to treat the sewage pumped into the sewer network.
9 more elements
A method of locally processing sewage, comprising:
- receiving sewage from a local source of sewage and retaining the sewage in a holding tank of a receiving section of a local sewage processing unit to provide initial anaerobic processing of the sewage;
- processing a portion of the sewage from the receiving section in order to extract water from the sewage that is suitable for re-use;
- and
- pumping a portion of the residual sewage from the receiving section into a sewer network that transports the residual sewage to a central sewage treatment plant.
1 more element
A sewage treatment process comprising:
- separately processing a plurality of local sources of sewage according to a method comprising:
- receiving sewage from a local source of sewage and retaining the sewage in a receiving section of a local sewage processing unit;
- processing a portion of the sewage from the receiving section in order to extract water from the sewage that is suitable for re-use;
- and
- pumping a portion of the residual sewage from the receiving section into a sewer network;
- wherein said separate processing is done in order to extract water from each of the local sources of sewage that is suitable for re-use;
- pumping sewage from the receiving section of each local sewage processing unit into the sewer network;
- and
- processing at a central sewage treatment plant sewage that is pumped into the sewer network from each of the local sources of sewage.
