3D TRASAR Bio-Control/3D TRASAR Bio-Shock Start-Up
Procedure (con’t)
Bio-reporter Pellet Feeder (recommended for system volumes between 12,000 and
2,000,000 gallons)
• TURN ‘
OFF
’ Pellet Feeder and 3D TRASAR Controller (pellet feeder power switch is
located on the bottom of the feeder near cable connectors).
• Connect pellet feeder to controller using pellet feeder cable (see Section 2 for wiring
details).
• Fill pellet feeder hopper with pellets, insert desiccant (from pellet container) in hopper lid.
• Ensure water flow through pellet feeder is between 4 and 5 gpm.
• Do not feed bio-reporter directly upstream of skid/fluorometer sample stream inlet.
• Do not feed bio-reporter into a low flow/mix or dead leg portion of system.
• Do not feed bio-reporter into a makeup water stream if flow is intermittent.
• Return pellet feeder discharge directly back to tower basin or tower return header.
• Turn ‘
ON
’ pellet feeder (power indicated by green LED) and 3D TRASAR Controller.
• Manually feed one pellet into the system to verify operation. At controller keypad press

Bio-reporter Liquid Feed Pump (use 3DTBR06 for systems <12,000 gallons, 3DTBR10 for
systems >500,000 gallons)
3DTBR06 recommended pumps:
.
• Grundfos DME (volume < 3,000 gallons):
P/N 6008505
• Iwaki EZB10 (3,000 to 12,000 gallons):
P/N 141-PJ4035.88
3DTBR10 REQUIRES an acid feed pump
• LMI pump
P/N 121-PJ2039.88
Important!
3DTBR10 is formulated with concentrated sulfuric acid. Use chemical feed
equipment compatible for feeding concentrated sulfuric acid into water streams.
•
Connect feed pump to control relay 3 (see Section 2 for wiring details).
•
Plumb pump suction tube to bio-reporter liquid container and ensure pump is primed.
•
Do not feed bio-reporter directly upstream of skid/fluorometer sample stream inlet.
•
Do not feed bio-reporter into a low flow/mix or dead-leg portion of system.
•
Do not feed bio-reporter into a makeup water stream if flow is intermittent.
•
Return liquid pump discharge directly back to tower basin or tower return header.
•
Manually turn on pump from the keypad to verify operation (see Section 4.10.8 for manual
relay control).
• Set pump feed rate between 0.1 and 0.2 gpd. Make sure pump does not lose prime at this
low rate.
