Introduction to TorayTrakTM
System performance normalization software
Custom program for Windows/Vista PCs written in Visual Basic using Microsoft Access for database management
Based on ASTM 4516 Standard for RO Data Normalization TorayTrak can be downloaded for free at our website:
www.toraywater.com
Advantages Over Excel Spreadsheet
Streamline file management and data transfer
Graphing engine for generation of custom graphs for quick data analysis
Multiple data entry methods
Pre-programmed method for acquisition of operating data directly from SCADA systems
Multiple Parameter Graphing
Depending on the number of stages, up to 51 different graphs of operating and normalized data can be made
Multiple Parameters On One Graph
Up to 4 parameters can be shown on one graph
Powerful Graphing Engine
Basic normalized data graphs can be quickly accessed
Cleaning required values can be customized and graphed
Multiple Data Entry Methods
Direct entry from SCADA system
Manual data entry
Custom entry using a combination of SCADA acquisition and manual entry
Other Graphing Features
Graphs can be saved as JPEG files for easy insertion into transmittals and reports
Up to 10 graphs can be quickly compared using the Graph Manager
Graphs can be easily configured (scales, symbols, line thickness, etc)
