General Information

Manufacture	Environmental Technologies, Inc.

Product/Model Name	ETI BWTS

Contact Information

(Name, Phone, e-mail)	Thomas L. Maddox, 800-940-8161,   HYPERLINK
"mailto:tlm@tlmcos.com"  tlm@tlmcos.com 

Are you the manufacturer or distributor?	Manufacturer

Product Availability	2012 to 2015 est

Certification status, include date certified or anticipated.

(IMO: G-8, G-9 [Basic and Final], Other)	None

Vessels using the system 

(Please provide Ship Name and/or location of land base test)	None

Technology Description

Technology used, please identify for all stages, if applicable.

	Filtration from existing Ships system(s)	Ozone

Ultrasound

Treatment location 

	Discharge piping during de-ballasting

Technology Description 

(Brief explanation of how the system operates)	The BWTS combines O3 and
sonic energy to treat upon discharge.

Effluent quality achieved 

(If possible, please provide any testing data showing effectiveness
during shore or shipboard testing.)	Please see the “Phase V 2008 Field
Testing” Attachment

Does the system use consumables?  

(If yes, please identify the consumables)	No. The BWTS use compressed
air to make O3, which is injected into the sonic reactor-piping module.

Installation/Operational Information

Is there any specific piping or tank configurations required for
installation/operation?

(Please explain)	There would need to be a loop at the location in the
ship where the ballast water discharge piping exits the ship.

Does the system require the ballast water to be mixed within the tanks? 
	No. The BWTS is operated upon discharge only.

Is there a minimum or maximum amount of contact/residence time required?

(Please explain)	We can treat a nominal 1500 m3/hr/6600 GPM, per ballast
pump, in a manifold system consisting 20 feet of 12 inch dia pipe upon
discharge.

Does the system incorporate any automatic or manual monitoring of the
effluent to ensure correct operation? 

(Brief explanation of requirements)	Yes.  “BallastWatch” Please see
the BallastWatch Attachment

Does the system increase the corrosion rate of the ballast tanks,
piping, or valves?  

(Steel, copper nickel, bronze materials)	No. The ballast water exits the
ship through the SS manifold as mentioned above.

Cost and Operating Information

	Small Unit

(~400 gpm/100m3/hr)	Medium Unit

(~3,000 gpm/700 m3/hr)	Large Unit

(~10,000 gpm/2,000 m3/hr)

Cost per Unit	$250,000.00	$350,000.00	$1,000,000.00 

Consumables Cost for 6 months of operation	$0.00	$0.00	$0.00

Estimated operating cost per m3 treated water	The only cost of operation
is the cost of  the electric power 	Same	Same

Annual Operating Labor Hours 	 Zero! Because the ETI BWTS is a very
automated and controlled system which can also, via, BallastWatch, be
remotely monitored via the web. 	Same	Same

Annual Maintenance Labor Hours	Because there are no moving parts or
filters, the maintenance time require should be less than 40 hours/
year.	Same	Same
