TOPICS DISCUSSED AND ACTION TAKEN 

I called Andy Adams from Layne Water Technologies at 3:20 PM on 9/26/11. Andy answered and was willing 

to share as much information as he is able to at a different time. We made a tentative appointment to speak on 

the phone tomorrow morning. He asked that I send him an email to waadams@laynewater.com with my contact 

information and he would be in touch tomorrow. 

Andy Adams called me back on 9/27/11 at 12:30. He provided me with the following information. 

 It is generally deployed for reducing wastewater volumes that would otherwise be injected for disposal. 

Installations of the EVRAS system are nationwide. Marcellus was mentioned specifically but no others. 

 The general operation involves using waste heat to raise the energy of the oil. The heated oil is 

circulated into a heat exchanger, where it transfers heat to the influent wastewater. The warm 

wastewater is routed to the top of the evaporation column it evaporators or falls back down to pit where 

it either crystallizes or exits as a concentrate stream. 

 Waste heat sources include compressors or exhaust. However, the unit can incorporate a gas burner if 

no waste heat is available. Vendor also indicated that operators have trucked or piped the water to the 

unit in the case that the waste heat source is not located directly on site. However, operators try not to 

do centrally located treatment but the EVRAS can be designed for such permanent structures with 

increased capacity. 

 Unit operates at about 200 bpd in winter and 450 bpd in summer due to ambient temperature 

 Only limitation of feed quality is Iron because it is an oxidizer. Did not have specific upper limits. 

 The unit is skid mounted and requires two separate trailers to be mobilized. 

 If the unit is utilizing waste heat, the only energy usage is for pumps and fans which totals to 30 kW per 

day at average operation of 300-350 bpd. Vendor did not report energy consumption if waste heat is not 

available. 

Vendor said he would respond with some more detailed documents that can provide costs, energy usage, and 

data from the field. He did not specify if he could find case studies or not. 

At 2:50 Andy Adams called back. Said he will be sending a drop box with a bunch of information on EVRAS 

as well as other technologies that the company offers. He also started talking about the oil and gas industry in 

general. He described how he has worked with two different well operators in the same general region. When 

asking them what the reuse criteria is for the treated wastewater he indicated that the two operators give 

significantly different ranges. He generalized TDS criteria for reuse as 20,000 to 30,000 mg/L but different 

operators may have a different range.
