Water Treatment Systems for Cooling Water Using New Polymer Technology

Abstract

In the recent cooling water treatment, it has been required the both of performance improvement and environmental measure of the chemicals. We developed new cooling water treatment chemicals (Neofilm® HC series and EX series) to meet these requirements.
“Dual Polymer System (DPS) ”, consisting of combination with the film forming polymer and the dispersant polymer, has been applied in these new chemicals as core technique. By using the DPS, it is able to reduce the content of zinc and phosphorus and, in addition, to improve the performance of the chemicals.
The chemicals which are using the DPS indicated high performance compared with traditional chemicals and commercialized chemicals in the evaluation test used cooling water simulator.
