Jewel Innova — Technical Due-Diligence Questionnaire

Client & Project Information

Basic information required to associate the technical data with the correct facility.

1 of 11

Company / Organization Name *

Plant / Facility Name *

Contact Person *

Designation *

Email *

Phone

Plant Location

Total Wastewater Generated per Day *

KLD = Kilolitres per day; MLD = Million litres per day. 1 MLD = 1,000 KLD.

Section A — Feed Water Quality & Variability

Critical for pretreatment, membrane selection, recovery and guarantees.

Step 2 of 11

1. Please confirm whether the supplied influent values represent: *

Average Maximum Minimum Single grab sample

2. Please provide minimum / average / maximum values over the last 30–90 days: *

Parameter	Minimum	Average	Maximum	Unit
Flow				m³/h
Temperature				°C
pH				—
Conductivity				µS/cm or mS/cm
TSS / Turbidity				mg/L / NTU
COD				mg/L

3. Are there any shock loads or batch discharges (e.g. CIP dumps, cleaning events, shutdown/startup events, rainfall inflow)? *

Yes No

4. Please confirm units and basis: *

Conductivity

Silica

Iron

5. Please provide full laboratory reports (APHA / ISO methods preferred), including detection limits.

Section D — Inorganics, Scaling & Corrosion

Essential for RO design, antiscalant strategy and recovery.

Step 5 of 11

15. Please provide full ionic analysis including:

Parameter	Value	Unit / Basis
Calcium		mg/L
Magnesium		mg/L
Total hardness (as CaCO₃)		mg/L
Alkalinity (as CaCO₃)		mg/L
Sulphate		mg/L
Nitrate		mg/L
Sodium / Potassium		mg/L
Phosphate		mg/L
Ammonia		mg/L

16. Confirm whether chloride (4 mg/L) is typical or minimum. Are higher values possible during cleaning events?

17. Please provide silica speciation if available:

Reactive Colloidal Unknown

18. Are any other metals present:

Section G — Reject / Brine Management

Major cost and feasibility driver.

Step 8 of 11

26. Can RO / EDI rejects be discharged to? *

Our system will recover 80% to 90% of treated effluent or operate a closed-loop system subject to final design.

Sewer / drain Existing ETP Cooling tower

27. Please provide discharge limits for reject streams (pH, TDS, COD, temperature).

28. Any disposal costs or restrictions (tanker, fees, evaporation)?

Section I — Commercial & Delivery Constraints

Information required for project planning and commercial evaluation.

Step 10 of 11

33. Available footprint (m²) and height restrictions?

34. Power availability and quality (DG backup, voltage stability)?

35. Target project timeline and budget expectations?

Documents Requested & Review

Attach supporting information so the final design and commercial offer can be based on verified data.

Step 11 of 11

Please attach available supporting documents

Latest laboratory reports (full chemistry)
Flow & temperature trends
Discharge consent / limits
Process description of effluent sources

Additional comments / information

Design & Commercial Note

Final design, recovery, guarantees and pricing will be based on the information confirmed through this questionnaire and supporting data.
