Kavya:

Shipping weight information is included in the draw ing I sent.

To estimate freight cost for unit only; you can use the following basis: 1. (1) truck per unit 2. Cost of mileage: $3.5/truck mile

Thus $3.5/truck mile x 1 truck/unit x 500 miles = $1750/unit

For the sand: assume a weight limit of 22 tons per truck; figure out how many trucks you need; and apply the sand per truck mileage cost as above.

Hi Miguel,

I have one (hopefully) final question for you on th e sand filters. Can you provide the approximate weight of the filters o r the cost to ship

the filters 500 miles?

Thanks again for all of your help.

The only major power requirements is the motive air requirements of the

process. This range from 1 to 8 scfm at a minimal pressure o f 30 psi.This air can be supplied by air compressors systems that are in the 5 HP

range.

Hi Miguel,

Could you also provide us the power consumption (if any) associated with

the sand filters?

Thanks, Kavya

Hi Miguel,

My name is Rekha Hareendran of Eastern Research Gro up, Inc., a contractor to the USEPA supporting the development of effluent guidelines for the steam electric power industry.

As I mentioned during our conversation, we are wor king on conceptual level costing of a chemical precipitation wastewate r treatment system to treat FGD (flue gas desulfurization) wastewater fro m steam electric power plants. As a part of this project, we are tr ying to collect cost information on different components or units of a c hemical precipitation
system.

I would really appreciate it if you could provide us the purchase cost, cost for ancillary equipments and the power consump tion (if applicable) for continuous backwash gravity sand filters.

-Flow range : 30,000 gpd- 1,000,000 gpd or 20 g pm-700 gpm (Please provide cost estimates for various flow rates in th is range).

If any of this information is considered confidenti al business information (CBI), do not send a written response v ia e-mail. Instead, please call Kavya directly to discuss the details.

Please let Kavya know if you have any further quest ions. We look forward to hearing from you.

-Thanks,
