Super powdered activated carbon(SPAC) treatment system

Significant reduction in the amount of powdered activated carbon used

  • The amount of powdered activated carbon used is reduced to 1/3 or less by improving the adsorption efficiency
  • Space saving of contact ponds

Flash Mixer with Radial Blades

Effectively mixes flocculants with low power

  • High efficiency agitation reduces electricity costs to one third of that of conventional suspension-type agitators
  • Installation can be carried out without changing the existing building frame, thus reducing construction costs
  • Maintenance can be done on site, which saves repair costs for reduction gears

Enhanced Filtration Control System

To provide safe filtration pond management

  • Improvement of filtered water quality
  • Reduction of initial leakage
  • Backup sedimentation tanks treatment failure

Ozone generation system

Supplying tasty water

  • Deodorization and decolorization
  • Decomposition of offensive odor and bad taste substances
  • Decomposition of trihalomethane precursors

Flocculation agitation control system

Reduction of coagulation injection

  • Reduction of chemical costs
  • Reduction in the number of jar tests

Floc monitoring system

For monitoring of floc forming abnormality

  • Automatically and constantly monitoring flock particle size
  • Rapid detection of poor coagulation and chemical injection

Flocculation agitation control system

Reduction of coagulation injection

  • Reduction of chemical costs
  • Reduction in the number of jar tests

Upward-flowing manganese contact tower

Space saving

  • Installation space is less than 1/10 of that of conventional manganese contact filtration system
  • Achieved reliable and stable manganese treatment
  • No need for backwashing and easy maintenance

Ceramic membrane filtration system

Supplying safe and secure water for 100 years to come

  • No membrane breakage, ensuring the safety of filtrated water
  • Automatic operation in case of sudden changes in the turbidity
  • Space-saving, best suited for renewal projects

STEP type Tube Settler

To Prevent flock accumulation and easy maintenance

  • Reduction of maintenance costs by not requiring frequent cleaning and shading equipment
  • Prevention of clogging of tube settler and improvement of water quality

Flash Mixer with Radial Blades

Effectively mixes flocculants with low power

  • High efficiency agitation reduces electricity costs to one third of that of conventional suspension-type agitators
  • Installation can be carried out without changing the existing building frame, thus reducing construction costs
  • Maintenance can be done on site, which saves repair costs for reduction gears

CHEMILES

Non-chemical treatment of iron and manganese

  • To remove iron, manganese, and ammoniacal nitrogen from groundwater
  • No chemicals
  • Compared to rapid filtration, less than 1/3 installation space

UV-LED disinfection system

High-performance LEDs provide safe and secure water

  • New LED light, contributing to improved reliability and reduced environmental loads
  • Immediate light emission for operation without warm-up time
  • Low maintenance costs and protection against Cryptosporidium
  • Durable against repeated ON-OFF operation, and easy batch operation
  • Over 70,000 hours life cycle - more than five times longer than a mercury lamp
