Water Analysis Request
How to send a water analysis, the system type, the capacity and the current problem to our technical team so your case can be reviewed.

Overview
A water analysis request is how you give our technical team the information a treatment review depends on. Send the analysis report, the type of system, its capacity and the problem you are seeing. The more complete the picture, the more specific the technical discussion can be. Treatment rates and product choices are always set from the analysis and the operating conditions.
Why does treatment start with the water analysis?
The same chemical can work well on one water and badly on another. Hardness, alkalinity, silica, chloride, sulfate, iron, pH, conductivity and organic content decide which salts scale, how aggressive the water is to metal, and what the microorganisms find to feed on. A recommendation made without the analysis is a guess.
What should you send?
- the analysis report of the relevant water, with the sampling date and the name of the laboratory
- the system type: RO plant, cooling tower, closed chilled-water loop, or steam or hot water boiler
- the capacity or size of the system, in the units you normally use
- the source of the make-up or feed water, and any treatment ahead of the system
- the current chemicals and how they are fed
- the problem observed and how long it has been present
Which parameters matter for which system?
RO plants
Hardness, alkalinity, sulfate, silica, iron and manganese, pH, temperature, total dissolved solids, and organic content or silt density where available.
Cooling towers and chilled-water loops
Make-up and circulating water pH, conductivity, hardness, alkalinity, chloride, iron and copper, plus microbiological results.
Boilers
Feedwater hardness, oxygen and pH, boiler water alkalinity and conductivity, and condensate pH and iron.
What if you do not have a recent analysis?
Send what you have, together with the system details, and say that the analysis is old or incomplete. Some decisions can be discussed in principle, but a current analysis is needed before any product is proposed.
What happens after you send it?
Our technical team reads the submission and reviews it against the system details. This review is a technical discussion of your case. It does not promise a particular recommendation, a response time or a result.
What helps the review most?
- operating records over a period, not a single reading
- photographs or descriptions of deposits, corrosion or slime
- a note of recent changes: new source, new chemical, repair work
- the name of the person who can discuss the system in detail
How is a representative sample taken?
A result is only as good as the sample. Take it from a point that represents the system, after the line has been flushed, into a clean container supplied or recommended by the laboratory, and send it quickly. Note the temperature and the time. For a cooling or boiler system, take the make-up and the circulating or boiler water at the same visit so the two can be compared.
What does a good question look like?
A good question is specific: why did the differential pressure rise after the last cleaning, which inhibitor suits this make-up water, why does the condensate show iron. The more precise the question, the more useful the technical response. Mention what you have already tried and what you want to decide.
Is the information kept confidential?
Operating data is used to review your case. How submissions are stored and handled is described in the privacy information of the site.
Complete the form with the analysis and your system details, and our technical team will take it from there.
Applications
The request applies to any water system the company supports: RO plants, open cooling towers, closed chilled-water loops and boilers. Typical senders are plant and utilities managers, facility management teams, MEP consultants and contractors preparing a specification.
Existing plants with a problem
Scale, rising differential pressure, corrosion, slime or foam: the analysis helps separate a water problem from a mechanical or operating one.
New systems under design
Consultants and contractors send the source water analysis early so that the design and the treatment program are consistent.
Changes of source or process
A new supply, a higher recovery or a change in the cooling load changes the balance, and a fresh analysis shows the effect.
Procurement and specification
Buyers and consultants use an analysis to write a specification that suppliers can answer on the same basis, which makes proposals easier to compare.
Submitting a request does not commit either side to any supply.
Problems this addresses
Problems
What causes RO membrane scaling and how is it controlled?
RO membrane scaling is the crystallisation of sparingly soluble salts on the membrane as the concentrate becomes saturated. See the signs, causes, checks and the treatment approach.
Problems
What causes scale in cooling towers and how do you stop it?
Cooling tower scale forms when evaporation concentrates hardness and alkalinity beyond their solubility. See the signs, causes, checks and the scale inhibitor approach.
Problems
What causes scale and deposits in boilers?
Boiler scale forms when hardness, silica and iron deposit on heated surfaces. Learn the effects, causes, the checks to run and the scale and corrosion inhibitor approach.
