Predictika · Water treatment system quotes

An AI sales agent's reverse osmosis quote, checked against the feed water before it goes out

An AI sales agent prepares a quote for a large reverse osmosis system for a customer's site. Before it goes out, the agent sends it to Predictika, which checks the system against the customer's feed water analysis, flow and power supply, and the figures the quote states, using a declarative model of the published datasheet limits. The validator returns a verdict, every reason and the figures it computed.

Scope: Large LennRO reverse osmosis systems, LBW-L (tap and low brackish water) and HBW-L (high brackish water), 5 to 50 m3/h of permeate. See everything this validator covers

This validator models orders for the large LennRO reverse osmosis systems, not just the scenarios shown below.

  • Systems — the LBW-L series (tap and low brackish water, feed up to 1,000 ppm) and the HBW-L series (high brackish water, feed up to 6,000 ppm), each in the 5, 10, 20 and 50 m3/h sizes. Feed flow, pump power, recovery and permeate quality come from the datasheet for the chosen series and size.
  • Feed water limits — total dissolved solids, temperature (15 to 25 degrees C), silt density index (below 3), dissolved iron and manganese, chlorine, pH (2 to 11 in continuous operation) and inlet pressure (2 to 4 bar), with the datasheet's own wording for each series (for example, less than 0.05 ppm iron on LBW-L, at most 0.05 ppm on HBW-L, and no chlorine on HBW-L).
  • Site and quote checks — the system must deliver the permeate the site needs, at the quality the site requires; the site must supply the feed flow and the power for the high pressure pump; and the feed flow and pump power stated on the quote must equal the datasheet figures.

Any order for these systems that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Lenntech publishes no price list for these systems, so this validator produces no price build-up or line-item quote), the small LennRO systems (250 to 2,000 L/h), the brackish version up to 3,000 ppm, ultrafiltration, softening and disinfection units, optional equipment (feed pump, antiscalant dosing, softener, CIP station), and the datasheet limits for turbidity, oil and grease and COD.

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
Feed water limits that differ between seriesOnly with care
Each limit is a rule per series, and the datasheet wording differs ("less than" on one series, "at most" on the other, no chlorine at all on HBW-L). It works, but every limit is another rule to write and keep right.		The water analysis is in one request and each series is checked against its own limits at once.
A series that cannot take the customer's feed waterOnly with workarounds
A standard quote has no fields for a water analysis, so the salinity, iron or chlorine is typed into notes or a custom form; the check then depends on someone entering and reading it.		The feed water analysis is part of the request, so a series that cannot take the water is blocked with the reason.
A system that is too small, or a site that cannot feed or power itOnly with care
Capacity, feed flow and pump power depend on the series and size; each comparison with the site needs its own calculation.		Capacity, feed flow and pump power are computed on every call and compared with what the site needs and supplies.
Figures on the quote that differ from the datasheetOnly with care
A stated figure is a free-entry field; a rule can compare it with a computed one, but someone must write and maintain it.		The stated figures travel with the quote and are compared with the datasheet 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 rep fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for a large reverse osmosis system for a customer's site. Before it goes out, the agent sends it to Predictika, which checks the system against the customer's feed water analysis, flow and power supply, and the figures the quote states, using a declarative model of the published datasheet limits. The validator 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 a LBW-L 50 m3/h reverse osmosis system for a site that needs 45 m3/h of permeate with total dissolved solids below 250 ppm. The feed water has 650 ppm total dissolved solids, a temperature of 19 degrees C, an SDI of 4.2, 0.02 ppm dissolved iron. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The feed water silt density index (SDI15) is 4.2; it must be below 3. The feed water has 0.4 ppm free chlorine; the LBW-L datasheet requires less than 0.1 ppm. The feed pressure is 1.8 bar; these systems need 2 to 4 bar at the inlet.
    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 a system that is too small, or a site that cannot feed or power it, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the silt density index to 2.4 and the chlorine to 0 ppm.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The feed pressure is 1.8 bar; these systems need 2 to 4 bar at the inlet.
    12. 
      
  12. Two findings cleared. Still blocking: feed pressure out of range.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the feed pressure to 3 bar.
    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.
