contaminant
level

• NaOcl : 0.4 ~ 1 ppm (with treatment of Ozone, it is reduced to 0.2 ~0.4ppm)
• pH: 5.8~8.6
• Turbidity: 5 NTU
• Bacteria: 15% or less test results which exceed 200/1ml bacteria
• Coliform: should detect 3 or less in five 100 ml sampling water

Turbidity

• - Turbidity is the cloudiness or haziness of a fluid caused by suspended solids that are generally invisible to the eye. The measurement of turbidity is a key test of water quality.
• - NTU(Nephelometric Turbidity Units)
  

  Drinking water standard for NTU is 0.5, and Usual Tap water has 0.1 NTU. Water over 20 NTB is yellowish.

• - B. Semi-Public: 4 times / day (6hr)
• - C. Private: 3 times / day (8hr)

AMF filtration
Process

By implanting metal membrane inside of filtration equipment, suspended solids are removed by pressurized raw water and backwash water. Within low concentrated micron water, this process is capable of reducing holding hour and effective due to the benefit of the surficial filtration. Within AMF filtration process, swimming water remains clear and clean, free from harmful substances, bacteria, viruses, algae and other pathogens and suitable for use by swimmers.
