# Development of Chemical Precipitation Purchased Equipment

Costs:

Tanks

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 piping, valves, and

controllers.

The followin g telecons support EPA’ s development of cost element (2 ) by providing purchase costs and

information regarding FRP tanks used in the Steam Electric cost model.Project No.: 0172. 08 .02 9 .0 4 4 DISTRIBUTION

GENERAL SUBJECT: Vendor cost request for tanks for a chemical precipitation wastewater treatment system.

TOPICS DISCUSSED AND ACTION TAKEN

On Monday

, March 21 , 20 1 1 at 4:00 p m I contacted Augusta Fiberglass to obtain costs for tanks needed for

chemical precipitation wastewater treatment systems for FGD wastewater . I was directed to Mr. David Reuis. I

explained to M r

. Reuis that we are working on conceptual level costing of a chemical precipitation wastewater

treatment system to treat FGD (flue gas desulfurization) wastewater fr om steam electric power plants and a s a

part of this project, we are trying to collect cost information on different components or units of a chemical

precipitation system

. Mr. Reuis indicated that they had provided tanks for FGD wastewater treatment before.

I told Mr. Reu is that we would like to get purchase costs including ancillary equipment such as structural

supports and access walkways for multiple tanks. I told him that we had limited information including flow

rates and approximate residence times for most of the ta nks, as well as some additional information on the use

of the tank (e.g., lime would be added to reaction tank 1). For some of the tanks, I told him we would like his

opinion on the tank needed and the costs. He stated that as much information as we could provide would be

helpful for him to provide costs, however, they can estimate costs based on the flow rates and residence times.

I asked Mr. Reuis if there are any power requirements for tanks. He said that if any temperature regulation (i.e.,

insulation, heating) is needed there may be power requirements. I also asked if they could provide costs for

chemical storage tanks. He said they can do this and useful information would be the size of the tank, the

chemical stored, the percentage of the chemical and the temperature. He also stated that based on the

wastewater tanks chemical is added to, they can estimate the size of chemical storage tank needed. I also asked

Mr. Reuis if they could provide costs for mixers. Mr. Reuis stated that they could provide co sts for mixers but

when mixers are provided with the tanks, Augusta Fiberglass obtains them from another vendor and charges a

premium on the mixer cost. He stated it is cheaper for a client to go to a mixer vendor directly.

Mr. Reuis asked for the request via email and stated he could provide the information within a few days.Project No.: 0172.08.029.044 DISTRIBUTION

GENERAL SUBJECT: Vendor cost request for tanks for a chemical precipitation wastewater treatment system.

TOPICS DISCUSSED AND ACTION TAKEN

Mr. Michael Hawkins left me a voicemail in response to my call with Mr. Reuis. On Friday

, April 1, 2011 at

10:45 a m I contacted Mr. Hawkins to obtain costs for tanks needed for chemical precipitation wastewater

treatment systems for FGD wastewater

.

Mr. Hawkins stated that typically shop

- built, field

- erected tanks range from 10,000 gallons to 50,000 gallons in

size and would cost a pproximately $1.25/gallon to purchase. Field

- erected tanks range from 50,000 gallons to

250,000 gallons in size and would cost approximately $2.00/gallon to purchase. He said to account for ancillary

equipment, such as nozzles and baffles, the cost could b e escalated 15%. Mr. Hawkins also stated that the

largest tank (250,000 gallons) would have a diameter of 42 feet and height of 25 feet. The tank size is limited by

shipping constraints, such as low overpasses, particularly on the East Coast. Tanks larger than this size would

need to be field

- erected and built which would require a build shop on site, increasing the expense.

Mr. Hawkins stated that typically, ancillary equipment provided with the tank includes a mixer bridge, hold

down lugs, manways, bolts and gasket for manways, spare nozzles, and level connectors. Ancillary equipment

that may be required but is not included in the purchase cost includes shut off valves, outlet pumps, and external

piping.
