Common feed-water issues
Define the load before the equipment.
- High dissolved salts and osmotic pressure
- Hardness, silica and scale risk
- Iron, manganese, color or suspended solids
- Concentrate, backwash and sludge disposal
Source-water solution
Special Source Water
Treatment planning for difficult source water where incomplete analysis or an assumed process creates the greatest project risk.
Discuss Your Water RequirementsSpecial-source and difficult water
Treat the source, recovery target and residuals as one system.
Difficult feeds require a complete analysis before pressure, recovery, pretreatment or concentrate handling can be selected.
Treatment objective
Set a use-specific design basis.
- A verified use-specific product-water target
- Stable pretreatment protecting downstream membranes
- Recovery compatible with scaling and discharge constraints
- Residuals handling included in the design basis
Process selection logic
Compare conditional treatment routes.
These stages describe a planning sequence, not a fixed process or performance guarantee.
- 01
Obtain a representative laboratory analysis
- 02
Define product-water use and discharge constraints
- 03
Pilot or model pretreatment and membrane stages where risk warrants it
- 04
Confirm recovery, chemical use, residuals and monitoring before quotation

Turn the selected route into a project brief.
A concise project brief is more useful than selecting a catalogue model first.
- Feed-water source and a current laboratory analysis when available
- Application, target water quality and point-of-use requirements
- Required flow, daily volume, operating hours and storage needs
- Destination, utilities, installation constraints and documentation needs
FAQ
Questions about special source water.
What analysis is needed for high-TDS water treatment?
Include conductivity or TDS, major ions, hardness, alkalinity, silica, iron, manganese, turbidity, organics where relevant, temperature and any seasonal variation.
Can softening reduce TDS?
Conventional ion-exchange softening exchanges hardness ions but does not normally reduce total dissolved solids. RO or another desalination process may be needed for a lower-TDS target.
How are iron and manganese removed?
The route may include oxidation, contact time and filtration, but pH, dissolved species, organics and the required residual concentration determine the design.
