An AI sales agent's desalination train quote, checked before it goes out

An AI sales agent specifies the energy recovery equipment for a reverse osmosis train: the pressure exchanger series and how many devices, the flow through each device, the pressure, the circulation pump and the figures the quote states for the series. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in the public Energy Recovery 2024 Water Products Catalog and returns a verdict, every reason and the figures it computed.

Scope: Energy Recovery PX Pressure Exchanger series (PX U, PX Q, PX Q400, PX L, PX PowerTrain) with the AquaBold, VPXP, HP and UHP circulation pumps: flow, pressure, pairing and stated figures. See everything this validator covers

This validator models the pressure exchanger and circulation pump figures in the public Energy Recovery 2024 Water Products Catalog, not just the scenarios shown below.

  • Pressure exchanger series — the flow range per device (PX U 10 to 250 gpm, PX Q 20 to 400, PX Q400 290 to 400, PX L 30 to 260, PX PowerTrain 800 to 3,000), the pressure rating (1,740, 1,200, 1,200, 400 and 1,200 psi) and the peak efficiency (95, 98, 98, 97 and 98 percent).
  • Flow and pressure — the flow through each device must fall within the series range, and the pressure within the series rating.
  • Circulation pumps — the pump flow range and pressure rating of the AquaBold (by frame size and number of stages), VPXP, HP and UHP pumps, the permeate range that suits the HP and VPXP pumps, and the catalog's pairing of the UHP pump with the PX U series (a different pairing goes to a person to confirm).
  • Stated figures — the peak efficiency and rated pressure the quote states for the series must equal the catalog figures.

Any train specification built from these series and pumps is in scope — not only the scenarios pictured here. Not covered: prices (Energy Recovery publishes none in the catalog, so this page shows no price build-up), the turbochargers, the newer PX Q650, the individual models inside a series (the catalog gives their flow ranges only as a chart), membrane and feed pump design, and the Power Model Pro configurator. The catalog describes the PX U series as the ultra-high-pressure RO solution and pairs the UHP pump with the PX U40; where a quote departs from those descriptions the validator asks a person to confirm rather than blocking. The catalog edition read is March 2024.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Flow range that depends on the seriesOnly with workarounds
Each series has its own flow range per device, so a rules-based CPQ needs a rule or lookup table per series.		The series selects its range inside one model and the flow is compared in the same pass.
Pump limits that differ by pump and frameOnly with workarounds
The AquaBold flow and stage limits depend on the frame, the HP and VPXP limits on the permeate rate; each is a separate rule set.		Each pump selects its limits inside one model, in any order of choices.
Pairing between pumps and pressure exchangersOnly with care
A rule can flag the UHP pump with a series other than PX U, but it has to be written and kept in step with the catalog.		The pairing is a named finding that comes back with the verdict.
Efficiency and pressure stated in the quoteOnly with care
The stated figures are derived from the series, so a rule has to recompute them and compare.		The stated figures are fields in the request, compared with the catalog figures on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1The flow of 401 gpm through each device is outside the 20 to 400 gpm that this pressure exchanger series handles.
2The flow of 19 gpm through each device is outside the 20 to 400 gpm that this pressure exchanger series handles.
3The flow of 289 gpm through each device is outside the 290 to 400 gpm that this pressure exchanger series handles.
4The train operates at 401 psi; this pressure exchanger is rated up to 400 psi.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent specifies the energy recovery equipment for a reverse osmosis train: the pressure exchanger series and how many devices, the flow through each device, the pressure, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in the public Energy Recovery 2024 Water Products Catalog and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote the energy recovery equipment for a seawater reverse osmosis train: 3 PX Q400 pressure exchanger devices. The train makes 4,000 cubic meters of permeate a day. The rest of the request is on screen. The quote states a peak efficiency of 99 percent and a rated pressure of 1,200 psi for the series.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The pump flow of 600 gpm is outside the 264 to 528 gpm of this pump. 22 stages is outside the 6 to 20 stages of this AquaBold frame. The quote states a peak efficiency of 99 percent; this series lists 98 percent.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for flow range that depends on the series, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the pump flow to 400 gpm and the AquaBold stages to 18.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The quote states a peak efficiency of 99 percent; this series lists 98 percent.
    12. 
      
  12. Two findings cleared. Still blocking: stated peak efficiency does not match.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the peak efficiency as stated in the quote to 98 percent.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
