Entrainment of organisms through power station cooling water systems

Abstract

All the organisms in the cooling water (CW) flow taken in at a power station which are small enough to pass through the initial filter-screens proceed right through the CW system. This process is termed entrainment. As these organisms pass through the screen wells, the pump, the culverts, the condensers and thence to the outfall, they are subjected to a number of potentially lethal stressors
