PureSafe will deliver the water system per contract in January 2012.
The company was awarded the contract as a result of a competitive bidding process in which the system met the technical and economic criteria.
PureSafe COO Gerard Stoehr said the sale in a targeted primary market represents a breakthrough and validation of the features and benefits of the FRWS.
"In combination with our recent oil and gas application, this sale shows the range of pollution problems that we can address with our fully integrated treatment train," Stoehr said.
