“…UWSs are the sum of several elements that are managed separately to finally discharge into surface water. The current tendency, promoted by the EUWFD, is to treat the UWS as a single area of operations, where hydraulic infrastructures, WWTPs and point source discharges have to be managed from an integrated point of view (Murillo et al 2011). There are two basic types of sewerage systems, combined and separate.…”

“…ASP is arguably the most common biological process adopted in WWTPs worldwide (Pomiès et al 2013;Choubert et al 2011b;Murillo et al 2011;Gray 2005;Á lvarez et al 2002), although the characteristics of the reactors may vary in which concerns the hydraulic regime and the operating conditions, the latter mainly determined by the rate of recirculation of activated sludge (RAS). Operating conditions establish the loading rate, i.e.…”

The concerns on metals in urban wastewater treatment plants (WWTPs) are mainly related to its contents in discharges to environment, namely in the final effluent and in the sludge produced. In the near future, more restrictive limits will be imposed to final effluents, due to the recent guidelines of the European Water Framework Directive (EUWFD). Concerning the sludge, at least seven metals (Cd, Cr, Cu, Hg, Ni, Pb and Zn) have been regulated in different countries, four of which were classified by EUWFD as priority substances and two of which were also classified as hazardous substances. Although WWTPs are not designed to remove metals, the study of metals behaviour in these systems is a crucial issue to develop predictive models that can help more effectively the regulation of pre-treatment requirements and contribute to optimize the systems to get more acceptable metal concentrations in its discharges. Relevant data have been published in the literature in recent decades concerning the occurrence/fate/behaviour of metals in WWTPs. However, the information is dispersed and not standardized in terms of parameters for comparing results. This work provides a critical review on this issue through a careful systematization, in tables and graphs, of the results reported in the literature, which allows its comparison and so its analysis, in order to conclude about the state of the art in this field. A summary of the main consensus, divergences and constraints found, as well as some recommendations, is presented as conclusions, aiming to contribute to a more concerted action of future research.

“…For example, a dictatorial solution might satisfy the demand of the dictator first, then allocate what is left equally to each remaining member. A competitive solution could be found based on auctions [8]. A more collaborative solution could be based on giving an exactly equal share to each of the n agents.…”

Two principles of enduring institutions for selforganising resource allocation are congruence of the allocation method to the resources available, and participation of those affected by the allocation (the appropriators) in selecting that method. However, the principles do not say anything explicitly about the fairness of the allocation method, or the outcomes. In this paper, we complement these principles with canons of distributive justice represented as legitimate claims, which are implemented as voting functions that determine the order in which resource requests are satisfied. The appropriators vote on the weight attached to the scoring functions, and so selforganise the allocation method. Experiments with a variation of the Linear Public Good game show that this pluralistic selforganising approach produces a better balance of utility and fairness (for agents that comply with the rules of the game) than monistic or fixed approaches.

“…Understanding information resources, such as digital libraries or wikipedias, as a knowledge commons has been proposed [Ostrom and Hess 2006]. The use of auctions [Murillo et al 2011], traditionally considered as a centralized solution, to provide a mutable resource allocation method for an open decentralized system requiring provision and appropriation of reusable, multiple and/or indivisible resources, is being investigated.…”

Axiomatization of Socio-Economic Principles for Self-Organizing Institutions

We address the problem of engineering self-organizing electronic institutions for resource allocation in open, embedded, and resource-constrained systems. In such systems, there is decentralized control, competition for resources and an expectation of both intentional and unintentional errors. The "optimal" distribution of resources is then less important than the endurance of the distribution mechanism. Under these circumstances, we propose to model resource allocation as a common-pool resource management problem, and develop a formal characterization of Elinor Ostrom's socio-economic principles for self-governing institutions. This article applies a method for sociologically inspired computing to give a complete axiomatization of six of Ostrom's eight principles in the Event Calculus. A testbed is implemented for experimenting with the axiomatization. The experimental results show that these principles support enduring institutions, in terms of longevity and membership, and also provide insight into calibrating the transaction and running costs associated with implementing the principles against the behavioral profile of the institutional membership. We conclude that it is possible to express Ostrom's principles in logical form and that they are necessary and sufficient conditions for enduring self-organizing electronic institutions to manage sustainable common-pool resources.
