<strong></strong>James Wei, profesor del «Department of Chemical Engineering-MIT» empleó el concepto de paradigma en 1988, introducido por T. Kuhn, para caracterizar las etapas evolutivas de la ingeniería química. Wei identificó 3 períodos: el preparadigmático, un primer paradigma que lo relaciona con la publicación del texto Principles of Chemical Engineering, y un segundo paradigma asociado al texto: Transport Phenomena, de Bird, Stewart and Lightfoot, en 1960. Los paradigmas de Wei son reduccionistas y limitados y deben ser ampliados y actualizados. En el presente trabajo se identifican 3 etapas: el preparadigmático, el paradigma de las operaciones unitarias, y el paradigma de la ciencia de la ingeniería química. Se hace referencia a las nuevas fronteras de la ingeniería química y a la necesidad de incluir nuevas disciplinas académicas y nuevas técnicas de enseñanza-aprendizaje.

In order to improve ammonia removal capability from wastewater, zeolite was modified with heat and biofilm in this paper. The results showed that the adsorption capacity of heat modified zeolite could be reach mean value of 120.18meq/100g, which was 1.55 times than virgin zeolite. The results of bench scale experiments also showed that the data in the experiments were in line with Langmuir isotherms for ammonium ion absorbed onto heat modified zeolite. Moreover the biofilm which attached on the surface of heat modified zeolite only modified the surface feature of modified zeolite, while ion-exchange and diffusion procedure were not affected.
