Frequently Asked Questions

What devices and browsers support Avista AdvisorCi Online?

• PC’s and Apple computers running Chrome, Edge, and Safari are compatible.  If using Chrome on a PC, please give the application a few seconds to completely load when making a new projection.
• iPads are supported but are not recommended due to the high level of input required from the user
• iPhones and Android devices and Firefox are not supported

Why is the acid or caustic dose 0 when a pH adjustment is made?

• In order to accurately calculate the amount of acid or caustic needed for a pH adjustment, a feed stream must have bicarbonate and or carbonate in the feed.  If the feed stream has 0 for both, then it cannot calculate the acid or caustic needed.  Adding 10 ppm of bicarbonate will produce a more accurate brine pH and accurate acid or caustic dose.

What files can be imported?

• ADV files from both the legacy desktop application and AdvisorCi Online
• PDF files from the legacy desktop application of AdvisorCi
• Avista branded water analysis PDF’s
• Dupont Wave PDF’s for single stage RO systems
• Hydranautics IMS design PDF’s for single stage RO systems
• More file types will be added in the future

How do I change units?

• Under the account settings menu on the top right of the screen, users can switch between metric units and imperial units (lbs/gals).  This will change the units throughout the program.

What do I do if I see this icon in AdvisorCi Online?

• This icon means you have been logged out.  In order to maintain a high level of security, login tokens are only valid for several hours.  Using the program after this time has expired, will require you to log back in.  Pressing refresh will relog the user in, if required.

What happens if the graph does not print on the PDF?

• Use “Save As PDF” in Chrome, Edge, and Safari to generate the PDF projection.

What is Dynamic Mode?

• Dynamic Mode is a specialized mode that provides antiscalant curves suitable for semi-batch and other modulating RO’s that don’t use a traditional steady state RO.
  Dynamic Mode uses new dosing models for products specifically chosen for these applications. The products have different upper saturation limits when used in Dynamic mode, allowing for higher recovery levels when compared to a traditional steady-state RO.

Why don’t I see all the normal antiscalant products when I select Dynamic Mode?

• A subset of products typically used in these specialty applications have been added, further products will be added when testing is complete.

How do I access Dynamic mode?

• Dynamic Mode access is provided to customers designing or operating Dynamic RO systems. To obtain access please request this from your local representative.
  Dynamic Mode is accessible from the Projection Information screen. Normal mode is selected by default and can be changed to Dynamic Mode.

Does the program behave differently in Dynamic Mode?

• The program’s normal workflow and usage stay the same. Some programme visuals change to let the user know that the antiscalant calculations are being made in Dynamic Mode.

Will antiscalant doses be different between Normal and Dynamic modes?

• It is possible to get different doses between Normal and Dynamic modes as different dosing curves and saturation limits are applied in the different modes.
