In addition, temperature directly and indirectly affects all the factors that govern microbial growth. Temperatures outside the normal range can cause a significant discomfort to customers during both extremely hot and cold months. Maintaining a safe and comfortable temperature range (e.g., between 4 to 11 degrees C) in drinking water distribution systems throughout the year is a growing concern for water utilities worldwide. This gives water utilities unprecedented power to model temperature dynamics within their distribution systems for improved thermal design and operation and optimal safeguarding of public health. This feature can greatly assist water utilities in improving distribution design to minimize dirty water and forge closer ties with their customers.Īnother powerful and unique feature of H2ONet MSX is its critical ability to accurately simulate spatial and temporal variations in water temperature and temperature gradients throughout any water distribution system. It considers both settling of particles under gravity as well as deposition of particles on the pipe walls due to particle/pipe surface attractive forces. H2ONet MSX can also be effectively used to track the movement, fate and build up of particulate material in the water distribution system. It also accepts any number of user-specified (adding water quality) parameters and formulas for process models. In addition, the program allows users to input any mathematical models of physical, chemical, and biological reactions in the bulk water and on pipe surfaces. H2ONet MSX can effectively model any system of multiple, interacting chemical species.

While there are a number of commercially available programs for modeling the hydraulic and water quality behavior of drinking water distribution systems, their water quality component is limited to a certain number of fixed kinetic models, and to tracking the transport and fate of a single chemical species, such as fluoride or free chlorine. This structure gives users the flexibility to accurately model multi-source, multi-quality systems and a wide range of important chemical reactions including free chlorine loss, formation of disinfection byproducts, nitrification dynamics, disinfectant residuals, pathogen inactivation, chloramine decomposition, and adsorption on pipe walls. H2ONet MSX allows users to model very complex reaction schemes between multiple chemical and biological species in the water distribution piping system, both in the bulk flow and at the pipe wall. H2ONet MSX (Multi-Species eXtension) adds very powerful modeling capabilities including the unprecedented ability to accurately model multiple interacting contaminants (using water quality components rather than contaminants) as well as sediment deposition and re-suspension in drinking water distribution systems.
