InfoWater 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. InfoWater 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. 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.
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. InfoWater MSX can effectively model any system of multiple, interacting chemical species. 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. It also accepts any number of user-specified (adding water quality) parameters and formulas for process models.
InfoWater MSX lets users specify the mathematical expressions that govern the reaction dynamics of the system being studied. This allows users the flexibility to model a wide range of chemical reactions of interest. Examples include:
|• the auto-decomposition of chloramines to ammonia,|
|• the formation of disinfection by-products,|
|• biological re-growth including nitrification dynamics,|
|• combined reaction rate constants in multi-source systems, and|
|• mass transfer limited oxidation-pipe wall adsorption reactions.|
Particle Transport and Deposition
InfoWater MSX can also be effectively used to track the movement, fate and build up of particulate material in the 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. This feature can greatly assist water utilities in improving distribution design to minimize dirty water and forge closer ties with their customers.
Water Temperature Modeling
Another powerful and unique feature of InfoWater MSX is its critical ability to accurately simulate spatial and temporal variations in water temperature and temperature gradients throughout any water distribution system. 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.
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. Temperatures outside the normal range can cause a significant discomfort to customers during both extremely hot and cold months. In addition, temperature directly and indirectly affects all the factors that govern microbial growth. It therefore influences treatment plant efficiency, microbial growth rate, disinfection efficiency, dissipation of disinfectant residuals, corrosion and metal release rates, maintenance and chemical additive costs, and distribution system hydraulics and water velocity created by customer demand. InfoWater MSX enables users to model very complex heat transfer mechanisms between the water in the distribution pipes and the ambient environment. It directly considers the influence of ambient temperature, wall material and thickness, flow conditions, buried depth, and other pertinent variables that determine how much heat will intrude into the water in the distribution pipes. Ambient temperature can be the air temperature of the upper cover (soil, grass and pavement), and can be described as either a constant or a time-varying pattern.
InfoWater MSX gives water utilities the vital ability to maintain a relatively constant water temperature in their drinking water distribution systems within a desirable range and help them optimize their overall treatment and distribution processes and improve customer satisfaction.
Advanced Turbidity Modeling
InfoWater MSX allows engineers to directly model turbidity generation in their drinking water distribution systems, enabling them to proactively optimize the design and management of their flushing programs. It includes the critical capability to perform comprehensive turbidity analysis as part of a water quality simulation, a powerful tool for predicting discoloration events in water networks. Discoloration events normally occur as a result of hydraulic disturbances (e.g., transients, pipe breaks, high demands) and generally represent the main cause of customer complaints. InfoWater MSX calculates the change of turbidity volume ratio at pipe wall and the change of turbidity in bulk water, as a function of flow shear stress. Turbidity peaks are then tracked through pipes as discoloration material is released. The results of the analysis can be used to design effective flushing strategies aimed at improving water quality in the network and reducing these complaints.
