Commissioning

Before starting water commissioning, be sure to do the following in preparation.
1. Fill tanks with water.
Fill tanks with clear river water or similar up to the design water level.
2. Check the water gauge indication and for water gauge alarms.
Record and adjust the actual water level indication on the water gauge when filling tanks with
water to adjust the water gauge, and check for alarms.
3. Check for water leaking from tanks.
Mark the water level after filling tanks to the prescribed water level and then confirm that there is
no decline in water level after one day. Check for dissolution of concrete constituents as well.

 As water must be drained from the tank to repair it if leaks are found, we recommend
installing membrane modules after performing this inspection.
6-1-1 Water Commissioning
Carry out stand-alone commissioning for the devices below.
Stand-alone commissioning of devices: confirm that each device functions as stated in its specifications
and record major data such as velocity and electric current.
1. Take measurements and records for each device.
 Confirm the performance curves of fluidic devices such as pumps and blowers and record their
flow rate, pressure, rotational speed, electric current, etc.
For large rotational devices, vibration, noise, etc. may also be measured.
 Observe and record the flow caused by aeration in tanks.
2. Adjust measuring instruments including flow meters, DO meters, etc.
3. Perform automatic filtration operation.
Confirm that there are no suspended solids or bubbles in filtered water.
RE F ER E NC E
 Although treated water becomes clouded immediately after the start of filtration as
hydrophilizing agent applied to the membrane mixes into filtered water, it will normally
become transparent in about 10 minutes. Hydrophilizing agent also causes foaming in the
membrane tank to some extent, but this will disappear as hydrophilization proceeds.
