Abstract
A method of producing drinking water from wastewater comprises ozonating the wastewater and treating the wastewater with powdered activated carbon (PAC). The ozonated wastewater and the PAC are mixed together in a contacting zone. The mixture of PAC and wastewater is directed through a membrane filtration unit that separates a PAC rich concentrate from treated water. The PAC rich concentrate is recirculated to the contacting zone to increase the concentration of PAC in the contacting zone.
