Here are inputs, processes and outputs for wastewater recycling. Outputs represent services provided by wastewater recycling facilities.
Many terms are easily recognized as conventional waste management descriptions. However they occur through natural biological processes rather than high-energy & chemicals inputs. Each described process represents a single module which is possible to integrate with others according to available inputs & preferred output.
Photo: Input - raw sewage from tank truck. Often this is sprayed untreated on fields, contaminating grazing cattle with pathogens. However wastewater recycling takes another approach... Output - crops irrigated with treated water from a wastewater recycling facility
