  • Wenchang City Hotel
  • The concrete Bagband system was built in early 2015 and treats waste produced by the kitchen and lavatories.  It can handle the hotel’s water consumption needs throughout the year during peak and off seasons, which is approximately 30m3/d. The water quality from the outlet of the septic tank is COD 300 mg/L and NH3-N 40 mg/ L.  The treated effluent meets the requirements of Level A of the national “urban sewage treatment plant pollutant discharge standard” (GB 18918-2002). Maintenance is simple and the energy consumption is low since only 3 HiBlow 200 (2 on, 1 standby) are used during operation, about 0.16kWh/m3 wastewater.
