The TFA’s are

located right above

the grit screw.

There are 10

TFA1.50 diffusers.

The diffusers create

a rolling action in

the tank to wash

the organics from

the grit particles;

the diffusers are

mounted ~3’ above

the collection zone

allowing the grit to

settle out.

The piping material

for this application

is Schedule 10
