Mixers

Purchased Equipment Costs are the sum of the following cost elements:

(1) Pump Costs

(2) Tank Costs

(3) Chemical Feed System Costs

(4) Mixer Costs

(5) Clarifier Costs

(6) Filter Press Costs

(7) Sand Filter Costs

Each cost component includes the cost of freight and associated ancillary equipment such as

Hi Kavya,

How are you going to use this information? The brochures are not confidential, as we distribute 

these to customers. The freight estimate is simply that, a price estimate. That is not confidential 

either.

Hi Chris,
Thanks again for your help last year. At the bottom of your emails, there is a note stating all 

items in the email are confidential. Could you please confirm whether or not the mixer freight 

estimate and the mixer brochures you provided are confidential?

Thanks,

Kavya

Kavya,

To ship the lot of mixers below would require one flatbed, and a freight estimate is $3,000 for 

one truck (lot of mixers).

Hi Chris,

Thanks again for your help. I have one more question for you. Can you give me either the 

weights of the mixers or the cost of shipping a mixer 500 miles? Or would that cost already be 

included in the prices of the mixer you gave me over the phone? Any rough numbers you could 

give me would be great.

Thanks again!

Kavya,

I attached some mixer brochures. The portable mixer would be used for the lime slurry tank prep

tank.
Say hello to Paul and Roy for me!
