Factory-made Onsite Wastewater Treatment System

Factory-made Onsite Wastewater Treatment System

FujiClean Co., Ltd.

Developing a Wastewater Treatment Infrastructure Quickly and Cost-effectively by FujiClean's System

FujiClean system consists of FRP tanks and air blowers. The wastewater treatment technology is based on the biofilm process to remove organics and nitrogen effectively in the wastewater from toilet, kitchen, laundry and shower. The treatment capacity per one unit ranges from 1.0 m3/day to 40 m3/day.

Major Features and Advantages

  • Certified products in Japan, the US, Australia and Germany.
  • Easy to maintain compared with centralized wastewater treatment plant.
  • Reliable products produced by originally developed semi-automatic molding method.
  • Comparable performance to centralized wastewater treatment plant. Organic loading discharging from the FujiClean system to a water body is 1/5 of a conventional septic tank system.
  • FujiClean system uses energy-saving diaphragm in air blower to reduce power consumption which contributes to low-carbon emission.

Possible applications

FujiClean wastewater treatment system enables to develop wastewater infrastructure quickly and cost-effectively in prioritized area by taking advantage of the on-site treatment while developing centralized sewer requires a lot of time in case of unfavourable geographical and geological conditions.

There is a chance to use the effluent from FujiClean system for irrigation since the treated water is as clean as from centralized wastewater treatment plant.

Competitive advantage

  • FujiClean’s small footprint system, which has been realized through 60 years of R&D history, enables easy engineering work.
  • A public work evaluation report issued by Ministry of Land, Infrastructure, Transport and Tourism indicates that the initial cost of FujiClean system is 50% of conventional centralized wastewater treatment plant in small communities with a flowrate of 300 m3 per day or less.
  • FujiClean system can reduce electric cost by 20 – 35% by the high efficiency treatment process and energy saving diaphragm air blowers compared with the other aerobic treatment technologies using diaphragm air blowers.
