Use Tenselo WTR-022 to screen a water analysis before choosing treatment equipment. This example shows water-treatment professionals how the software handles laboratory units, reporting limits and the evidence still needed for design.
How water test interpretation works
Follow the same bore-water sample from its entered values to the report's unresolved checks. The page references below open the existing PDF.
Enter the laboratory results and site duty
The sample uses a 60 L/min bore-water supply, 350 kPa available pressure and eight operating hours per day. Enter each result with its own unit and reporting qualifier: iron is 800 µg/L, conductivity is 0.75 mS/cm and arsenic is <2 µg/L.
See the entered values on page 4Read the parameter-by-parameter screening
The report retains the entered values alongside converted units, including iron at 0.80 mg/L and conductivity at 750 µS/cm. It flags iron and hardness for further assessment and keeps the less-than qualifier on arsenic.
See the results table on page 2Resolve missing evidence before final sizing
E. coli and total coliforms were not tested. The report therefore cannot confirm fitness for drinking. Missing manganese and hydrogen-sulphide results also prevent quantitative sizing of the iron-removal stage; the pressure budget remains withheld.
See the warning and withheld checks on page 1Review the preliminary treatment pathway
The sample proposes iron removal, softening and a final disinfection barrier. A water-treatment specialist must resolve the missing evidence and check the proposed equipment, backwash needs and pressure losses before completing the design.
Continue to treatment-process selection
What this example demonstrates: unit handling, traceable input values and explicit gaps in the evidence. It uses hypothetical inputs, and the report's date and design status remain visible. Calculator execution requires authorised application access.
What to enter from the water test
Start with the water source, intended use, design flow, inlet pressure and operating hours. Add every reported laboratory value with its own unit. WTR-022 accepts mixed-unit reports, including mg/L, µg/L and mS/cm, and retains less-than qualifiers for non-detect results.
Leave an untested parameter blank. A blank manganese or E. coli result means the evidence is missing. It does not mean the concentration is zero. The calculator also checks the stated hardness basis and can compare a measured total hardness against the value implied by calcium and magnesium.
| Input group | Examples | Why it matters |
|---|---|---|
| Use and source | Drinking, irrigation or process water; bore, rainwater, surface water or mains | Source risk and the required treated-water quality change the assessment. |
| Hydraulic duty | Peak flow, daily volume, available pressure and operating hours | A treatment process must meet the required duty and backwash or cleaning demand. |
| Laboratory chemistry | pH, EC, TDS, hardness, alkalinity, iron, manganese and major ions | These values identify scaling, staining, salinity and treatment risks. |
| Microbiology | E. coli and total coliforms | A private supply cannot receive a complete drinking-water screening without microbiological evidence. |
Worked bore-water interpretation
This static example was originally run in WTR-022 on 15 September 2026 and regenerated in the current report format on 22 September 2026. The bore-water duty is 60 L/min, or 3.60 m³/h, with 350 kPa available pressure and eight operating hours per day. The sample includes pH 7.2, TDS 450 mg/L, turbidity 1.2 NTU, temperature 18 °C and alkalinity 180 mg/L as CaCO3.
| Parameter | Laboratory entry | Displayed interpretation |
|---|---|---|
| Electrical conductivity | 0.75 mS/cm | 750 µS/cm with the original unit retained |
| Iron | 800 µg/L | 0.80 mg/L and flagged for further assessment |
| Arsenic | <2 µg/L | <0.0020 mg/L with the less-than qualifier retained |
| Total hardness | 250 mg/L as CaCO3 | Hardness basis retained and flagged for further assessment |
| Manganese | Not tested | No zero concentration assumed |
| Microbiology | E. coli and total coliforms not tested | Fitness for drinking cannot be confirmed from this report |
Result: the example identifies hardness and iron for further assessment, preserves the arsenic reporting limit and lists the missing manganese and microbiological evidence. It does not clear the water for drinking.
From interpretation to treatment sizing
WTR-022 can propose a preliminary sequence such as sediment filtration, iron removal, softening, activated carbon, membranes or disinfection. Each proposed stage links to its separate sizing calculation. The treatment order still needs review because one stage can affect the next stage's chemistry, pressure and fouling risk.
Continue with water-treatment process selection, water softener sizing, iron and manganese removal, reverse-osmosis design or ultrafiltration sizing.
What a single laboratory report cannot decide
Final equipment selection also depends on seasonal water quality, particle-size distribution, peak and continuous flow, the available backwash supply, waste disposal, material compatibility and the quality required after treatment. The Australian Drinking Water Guidelines provide a management framework rather than a substitute for local regulator requirements, competent review and conditions beyond the source sample.
Questions
Can software interpret a water analysis report?
Tenselo can organise and screen entered results, preserve units and non-detect qualifiers, identify missing evidence and propose preliminary treatment stages. A water professional must review the result and the complete laboratory report.
Can Tenselo tell me which water filter I need?
It can connect the identified water-quality problem to a preliminary treatment stage and a detailed sizing calculator. Final filter and media selection still depends on the full analysis, flow, pressure, variability, waste arrangements and current supplier data.
Does a blank laboratory result mean zero?
No. WTR-022 treats an untested parameter as missing evidence. It does not convert a blank result into a measured zero.
Can Tenselo certify that water is safe to drink?
No. Tenselo is a design aid. It does not replace a complete laboratory program, a drinking-water management plan, regulator requirements or review by a competent specialist.
