Water minimisation studies are often hampered or prevented by insufficient, inaccurate or conflicting water and contaminant balance data. WaterTracker is a tool designed to address this problem by quickly describing your existing network, determining the minimum additional measurements required and then identifying and resolving data conflicts. WaterTracker was designed to help any engineer facing the task of achieving a water and contaminant balance based on limited data of variable quality. With WaterTracker you can produce accurate, reconciled balances in a fraction of the time taken by other approaches.

WaterTracker provides a highly intuitive user interface for setting up the water network, providing drag-and-drop drawing features and easy point-and-click data access. WaterTracker provides many standard water-related unit operation models, such as Reverse Osmosis, D.A.F, various filter and stripper models, etc. and a model design wizard for producing customised models of your own unit operations.

After you have created a valid network structure the unique metering analysis facilities will minimise the time and cost of improving the quality and reliability of the balance. This is done by identifying which flow rate or concentration will eliminate most uncertainty if measured next. As more data is entered into metering analysis continues to direct your efforts towards the remaining key measurements. The software will also allow you to test the effectiveness of different meter sequences to allow the development of the most effective metering plan in advance of taking any additional measurements.

Data entry and conflict resolution

Flow rate and concentration data are entered with a trust category that indicates how reliable each value is. WaterTracker will rigorously check your data and, should a conflict arise, use the confidence values to relax the least trustworthy data item(s) to find a solution. Where conflicts can not be resolved, the software indicates the data items that are causing the conflict.

Optimising the network

In many cases a better understanding of the water network will lead to identification of easy-win water minimisation opportunities. For an in depth analysis and a fully optimised water network the results from WaterTracker can be quickly be transferred to WaterPinch to identify the best opportunities for water recycle, regeneration and treatment.
