Use only Schedule 40 or Schedule 80 polyvinyl chloride (PVC) pipe and fittings. Use only PVC
cement formulated for wet condition and fast installation to ensure connection between PVC
pipe to PVC fittings. Follow PVC cement
manufacturer’s recommendations on cure time before
wet testing the system. Do not use black, ABS piping or mix ABS pipe with PVC pipe or fittings.
All PVC pipe connections must be airtight and leakproof.
Failure to provide airtight suction
pipe connections may negatively impact nanobubble generator performance
. Large
bubbles visible at the pump strainer basket are an indication of suction pipe leaks. Difficulty with
pump priming may also be the result of suction pipe leaks.
Gas Connection
For BLOOM models without onboard gas generation, connect a high pressure rated oxygen gas
line to the standard CGA-022 fitting connection. Adjust the oxygen gas regulator on the gas
supply to 100
– 120 PSIG.
DO NOT EXCEED 140 PSIG SUPPLY GAS PRESSURE. Excessive pressure may
void warranty and compromise gas seals resulting in a sudden drop in backpressure.
Flooded Suction Installation
Refer to Figures 2 and 3 to determine whether the installation has a flooded suction pipe. A
flooded suction exists when the pipe between the tank and the BLOOM pump completely fills
with water when the pump is off and isolation valves are open (i.e., when the tank water
surface level is above the suction intake and the BLOOM pump). Refer to Figure 7
for BLOOM
enclosure dimensions and suction and discharge fitting locations.
