Project Description

This project will evaluate a transformational low energy (less than 200 kilojoules/kilogram water) waste heat coupled forward osmosis (FO) based water treatment system (the Aquapod©), adapted to meet the complex and unique environment of a power plant, to manage effluents, meet cooling water demands and achieve water conservation. The target is to enable recovery of at least 50 percent of the water from highly degraded water sources without extensive pretreatment in a cost effective manner.

Project Benefits

The use of the Aquapod© FO process can double to quadruple the amount of water recovery from power plant effluents per unit of input energy compared to the current state-of-the-art. It is also an intrinsically safe process unlike the current state-of-the-art which utilizes gaseous ammonia. Project outcomes will enable the early stage evaluation of a transformational water treatment system adapted to the power plant environment. A partner utility is engaged early in the technology development to assure that results would be applicable to large scale coal-fired power plants.
