Different Treatment Processes Wastewater Water Drinking

The ICWT (Intelligent Compact Wastewater Treatment System), the integrated compact Wastewater treatment equipment developed by OriginWater for point source wastewater, is applicable to the treatment of small and medium-sized dispersed sewage and similar industrial wastewater. In order to meet different demands, ICWT can be integrated with any basic modules or a variety of processes. There are ICWT-A, ICWT-B and ICWT-T types of products.The product has been awarded with the First Prize of Science and Technology of Membrane Industry Association of China, the Zhongguancun New Technology and New Product, the Single Champion Product In Manufacturing Industry, the Beijing New Technology and New Product, the Beijing National Product as well as ten more patents.The investment for ICWT integrated equipment series is about RMB 2000~28000 Yuan/m3, the investment for pretreatment and equipment foundation and other facilities is about RMB 1500~5500 Yuan/m3, the direct operating cost (electric charge + chemical cost) is about RMB 0.2~2 Yuan/m3.  ICWT integrated equipment has been widely applied in 28 provinces and cities, such as Beijing, Jiangsu, Zhejiang, Sichuan, Guangdong, Yunnan, Hubei, Anhui, Hainan, Guizhou, Hunan, Chongqing, Hebei (Xiong'an included), Henan, Tianjin, Inner Mongolia Autonomous Region, Fujian, Gansu, Guangxi, Jilin, Heilongjiang, Liaoning, Shandong, Shanxi, Shaanxi, Jiangxi, Tibet, Xinjiang and so on. At present, nearly ten thousand sets have been used and 600,000 m3 /d is recently reached. Thus, it is the ideal dispersed sewage treatment equipment.  Type ICWT/AType ICWT-A product is mainly used in the area with high requirements for effluent quality or sensitive to water environment and A/O-MBR process is adopted. The product is a fusion of two second prizes of National Science And Technology Progress Award, including "Membrane integrated wastewater deep purification technology"and"New technology of low energy consumption MBR wastewater recycling". The main water quality indexes can meet Level IV (TN ≤ 15mg/L) of Environmental Quality Standard for Surface Water (GB3838-2002), Level I-A of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB18918- 2002) and the Reuse of Urban Recycling Water-Water Quality Standard for Scenic Environment Use (GB18921-2002).Notes:1) The economic indicator refers to the ICWT system only; (2) Direct operating cost includes electric charge and chemical cost; the electricity price of electrical degree is calculated as RMB 0.6/(kW·h); (3) The general pretreatment includes influent tank, preliminary sedimentation tank, regulation tank and corresponding supporting equipment, etc., and the investment is about RMB 1,500~5,500/m3 according to different scales and construction standards.  Type ICWT/BType ICWT-B product is mainly used for higher effluent requirements for ammonia nitrogen and organic matters but no strict requirement of TN removal. Adopting O-MBR process, the product is to reach efficient removal of ammonia nitrogen and organic matters. The product is a fusion of two second prizes of National Science and Technology Progress Award, including "Membrane integrated wastewater deep purification technology" and "New technology of low energy consumption MBR wastewater recycling". The effluent quality meets the water quality standard for urban sewage reuse and the Reuse of Urban Recycling Water-Water Quality Standard for Urban Miscellaneous Water Consumption (GB18920-2002).Notes:(1) The economic indicator refers to the ICWT system only; (2) Direct operation cost includes electric charge and chemical cost; the electricity price of electrical degree is calculated as RMB 0.6/(kW·h); (3) The general pretreatment includes influent tank, preliminary sedimentation tank, regulation tank and corresponding supporting equipment, etc., and the investment is about RMB 1,500~2,500/m3 according to different scales and construction standards.Type ICWT/TType ICWT-T product is mainly used for low requirements for effluent quality and the traditional A/O + secondary sedimentation is adopted. The product is a fusion of advanced technologies, such as pulse aeration, air lift cycle, efficient clarification, etc. The effluent quality meets Level I-B of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plan (GB18918-2002).Notes:(1) The economic indicator refers to the ICWT system only; (2) Direct operation cost includes electric charge and chemical cost; the electricity price of electrical degree is calculated as RMB 0.6/(kW·h); (3) The general pretreatment includes influent tank, preliminary sedimentation tank, regulation tank and corresponding supporting equipment, etc., and the investment is about RMB 2,000~5,500/m3 according to different scales and construction standards; (4) *The air pump of the aeration equipment is replaced with the blower and the energy consumption is increased because of increased effective depth of this model, resulting in o
