This is what a buyer checks before they shortlist energy, mining, water and environment suppliers.
What does a plant operator check before selecting water treatment?
They check the treatment against their actual raw water analysis, the treated water specification achievable, and the ongoing consumable and energy cost. A system selected without a water analysis is a system that will underperform and be blamed on the supplier.
A plant engineer needs treated water to a specification and is comparing systems that all claim to achieve it.

First, what the product is
The fields a buyer scans before deciding whether you are worth contacting. Missing one of them usually ends the visit without an email.
- 1
Treatment technology
Filtration, softening, reverse osmosis, ion exchange and disinfection differ.
- 2
Feed water range handled
Treatment depends entirely on the raw water.
- 3
Treated water specification achievable
The output the process requires.
- 4
Capacity and recovery rate
Recovery determines waste and running cost.
- 5
Consumable and energy consumption
Usually exceeds the capital cost over time.
- 6
Footprint and utility requirements
Installation constraint.
- 7
Automation and monitoring
Determines operator attention required.
Then the paperwork
Naming the documents you can issue is what separates a supplier who can be audited from one who cannot.

The shortlist moment
A buyer lines up a few suppliers and keeps the ones whose proof is easy to check. The rest get a closed tab, not an email.
The buyer asks: What does a plant operator check before selecting water treatment?
A few suppliers get compared side by side:
A supplier with Technical specification and performance data on the page
Capacity, recovery, treated water quality and consumption
A supplier with Water analysis requirement on the page
The raw water data needed to design correctly
A supplier with Performance guarantee terms on the page
Guaranteed treated water quality and the remedy if not met

Questions suppliers ask
Why insist on a water analysis before quoting?
Because a system designed without one will underperform, and the customer will experience it as a product failure. Making the analysis a stated precondition protects your reputation and immediately distinguishes you from suppliers quoting from a catalogue.
How should running cost be presented?
As consumables, energy and waste per unit of treated water, with the assumptions shown. Operators compare systems on cost per cubic metre over years, and a supplier who lays it out honestly competes where a cheap capital price looks less attractive.
What convinces an operator to change supplier?
Evidence about the specific failure they are experiencing, whether that is treated water quality, consumable cost or downtime. Structuring your material around those three problems reaches the operator at the point where they are actually deciding.
