The study focuses on America over which the Inter-American System of Human Rights exercises its jurisdiction, given that Human Rights normativism (promoted by the UN and the Human Rights regional systems) prevails at the legislative and public policy agenda of the States. Specifically, it is considered that the doctrine, concepts and principles established by the jurisprudence of the Inter-American Court of Human Rights (IACHR), are nowadays the valid patterns to explain the conceptions and reasoning schemes that lead the legislative and public policy activity in America. Additionally, the “control de Convencionalidad” developed in the region, encourages the constitutional judgments issued within the States to reproduce these concepts and principles, which have the effect of the non-application or expulsion of legal rules and, through normative or structural judgements, the courts projects specific public policy, all of which could be considered a morphogenetic system. Thus, the main jurisprudential lines of the IACHR and the México’s Supreme Court will be analyzed in order to extract the elements and their attributes that make up the systemic toolkit for policy modelling and lawmaking and identify which behavioral patterns have been displaced to the environment that affects the system.

Nitrification of high total ammonia nitrogen-strength wastewaters is challenging due to free ammonia (FA) inhibition of nitrification. FA inhibition can potentially be alleviated by temporarily adsorbing ammonium (NH 4 + ) to natural zeolite, such as chabazite, followed by direct zeolite bioregeneration via nitrification. In this research, the effectiveness of chabazite addition for reducing nitrification inhibition during treatment of centrate from anaerobic digestion of swine waste was quantified. A mathematical model was developed that accounts for ion exchange of NH 4 + and sodium at the chabazite surface, surface diffusion of adsorbed NH 4 + within the chabazite grains, sequential nitrification of aqueous NH 4 + to nitrite and nitrate, and inhibition of nitritation and nitratation rates by NH 4 + . The model was calibrated using results of abiotic ion exchange and nitrification studies. Subsequently, nitrification tests were carried out with synthetic wastewater with a NH 4 + -N concentration of 1000 mg L -1 , with and without chabazite. A chabazite dose of 150 g L -1 decreased the FA concentration to below the inhibitory level and increased the nitrification rate from 0.16 to 0.36 mg-N (g-VSS) -1 h -1 . Following calibration, the model could predict the experimental data with no additional fitting parameters or parameter adjustment, in both the presence and absence of chabazite. The results suggest that the mathematical model provides a theoretically sound conceptual understanding of ion exchange assisted nitrification.
