And Control

Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. In this paper, information relevant to cases of nosocomial infections involving water circuits as a source of contaminants is compiled, with emphasis on the importance of microbiological control strategies to prevent the installation, spreading and growth of microorganisms in hospitals. An overview of the worldwide situation is provided, with emphasis on Brazilian hospitals. Different approaches normally used to control the occurrence of nosocomial infections due to waterborne contaminants are analyzed, and the use of the polysaccharide chitosan for this specific application is briefly discussed.

This paper describes a project to integrate EPANET, Giris and SCADA to assist water engineers in assessing the water distribution system in city S. The integrated system simulates the flow and concentration of chemical contaminants in municipality's water distribution system. The integrated model is a powerful tool for routine planning and emergency response. The capabilities of the model can greatly assist in the decision making processes for network asset inventory, rehabilitation requirements, and financial planning. The system was tested using the S City database composed of approximately 13219 junctions and 14832 pipes whose diameter not less than 300 mm.

Hydraulic Valves

This work presents the modeling and simulation of a hydraulic network with four nodes and two branches that form a two-level water distribution system. It also proposes a distribution of hydraulic valves that allows emulating a leak using a valve and different network configurations, e.g., simple ducts, closed networks and branched networks. The network is modeled in the steady state considering turbulent flow. Numerical experiments are performed, and the results show that the proposed network is useful for the design of leakage diagnosis and control algorithms in different configurations and leakage scenarios.
