InfoWater MSX V12 Releases Latest Advances in Turbidity Modeling

Latest Version Delivers Unprecedented Power in Modeling Multiple Interacting Chemical Species and Predicting and Controlling Potential Discoloration Events

In its ongoing quest to equip the global water industry with the world’s most powerful and comprehensive GIS-centric infrastructure modeling and management solutions, Innovyze announced the worldwide availability of the V12 Generation of InfoWater MSX for ArcGIS (Esri, Redlands, CA). Engineers can now directly model turbidity generation in their drinking water distribution systems, enabling them to proactively optimize the design and management of their flushing programs.

While there are a number of commercial programs for modeling the hydraulic and water quality behavior of drinking water distribution systems, their water quality components are limited to a certain number of fixed kinetic models, and can only track the transport and fate of a single chemical species such as fluoride or free chlorine. InfoWater MSX equips utilities with unprecedented power to model multi-source, multi-quality systems and accurately assess the fate and transport of contaminant threats within them to best safeguard public health.

InfoWater MSX enables engineers to accurately model very complex reaction schemes between multiple chemical and biological species in water distribution piping systems, both in the bulk flow and at the pipe wall. This gives users the flexibility to model 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.

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 parameters and cross-dependent or independent formulas for process models. These capabilities give users unprecedented flexibility in accurately modeling individual or combined kinetics in drinking water distribution systems for improved water quality maintenance and management.

In addition, InfoWater MSX can be effectively used to track the movement, fate and buildup of particulate material in the distribution system. It considers both settling of particles under gravity and 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, creating closer ties with their customers.

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. It enables users to model very complex heat transfer mechanisms between the water in the distribution pipes and the ambient environment, directly considering 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. This gives water utilities the vital ability to improve thermal design and operation by maintaining a relatively constant water temperature in their drinking water distribution systems within a desirable range. It also helps them optimize their overall treatment and distribution processes and improve customer satisfaction.

The latest version 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.

“InfoWater MSX is a revolutionary product that mainstreams a host of new, highly advanced and unique modeling capabilities for distribution systems water quality and sediment transport,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, Dist.M.ASCE, NAE, the company’s President, COO and Chief Technical Officer. “We’ve combined the best innovations from Innovyze R&D with requests by our customers to create one of the most significant new product versions in our history. By giving water utility engineers easy access to comprehensive, leading edge water quality modeling tools like this, we can enhance their ability to consistently design, operate and manage safe, reliable drinking water infrastructures and effectively protect public health.”
