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
Cleaning required
values can be
customized and
graphed
Basic normalized
data graphs can be
quickly accessed
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)
