Abstract: Static and dynamic experiments were used to evaluate scale inhibition performance of polyaspartic acid derivative (PASP-SEA-ASP). The static experiments showed that the PASP-SEA-ASP had good scale inhibition performance and the scale inhibition rate exceeded 80% when the PASP-SEA-ASP was 2 mg•L^-1 and the solution temperature was 40 ^OC. In the dynamic experiments, almost no scale formed on the heat transfer surface and the fouling thermal resistance decreases extraordinarily with PASP-SEA-ASP treatment experiment compared with the experiment without treatment. The PASP-SEA-ASP could be used in industrial cooling water systems.
