TorayDS2 is the new RO design software from Toray, which according to the company press release, is designed to achieve faster calculations for design and analysis of Toray equipped RO systems. TDS2 will include the following major features and improvements:
- Easy and fast setup which even allows the software to run from a flash drive. On most Win7 systems, no setup is required at all.
- Runs on virtual Win7 machines inside different host OS (example. OSX, Linux etc.)
- Microsoft SQL CE server based database used for project storage and element information.
- Microsoft SQL server support for use in corporate networks – common data base for all users in network if desired.
- Project, case and revision management with fine graduation to manage multiple projections.
- Text search in database for fast localisation of projects, cases and revisions.
- Extensive ‘water library’ functions for all relevant streams in RO systems.
- Detailed adjustment facility for many pre-treatment options.

- Much faster calculation engine for multi-stage and multi-pass configurations.
- Choice of different Energy Recovery systems (Turbo and isobaric) included.
- Improved and more accurate scaling indices using USGS Pitzer calculation.
- Increased design flexibility as every single element in a pressure vessel is separately configurable in terms of age, fouling factor, salt passage and module type.
- User configurable process flow diagram for the display of specific process parameters.
- New ‘autoCalc’ function for instant calculation by the change of any process parameter – all connected parameters change while user adjusts a value.
- Easy Excel export of design results for creating a series of RO calculations for process parameter diagrams. This can be combined with the autoCalc function to create comprehensive performance predictions, based on many automated projection runs, for varying recovery, temperature, membrane age, system configuration etc. in very short time.
- Quick start for new RO designs by using hundreds of provided project templates
- Compatible to previous Toray RO design software with the possibility to import the older DS1 .tid files
