Once-Through System Treatment

A once-through cooling water system passes water through the heat exchangers only one time before discharging it.  Recirculation does not occur, therefore, mineral content of the cooling water remains virtually unchanged as it passes through the system.  Typically, large volumes of water are used and discharged in once-through systems. Nalco offers a full line of products for once-through cooling applications. 

With 3D TRASAR® technology control, your system can be monitored for optimal, cost-effective performance.
