Pilot test of advanced treatments combination of wastewater for groundwater recharge

To solve the water shortage problem, an artificial groundwater recharge system will be constructed in Beijing for wastewater reuse as a demonstration and training center. Design and operating experience for the demonstration plant was gained through pilot tests of advanced treatment technologies with soil infiltration of well treated secondary effluent. The test results showed that the selected treatment technology meets the recommended water quality criteria for groundwater recharge and the gas chromatography-mass spectrometer (GC/MS) analysis results showed significantly improved water quality.
