RO Membrane FAQs

Does Crystwater only supply Keensen RO membranes?

Crystwater mainly promotes selected Keensen commercial and industrial RO membrane products online. We can also assist with specified 4040 and 8040 membrane enquiries across major brands such as Dow / FilmTec, Hydranautics, Toray, Vontron and other equivalent membrane manufacturers.
Can Crystwater quote RO membrane models not listed online?

Yes. Some commercial and industrial RO membrane enquiries are handled as supply-to-order requests. If the required model is not listed, please send the membrane model, quantity, application, required timeframe and delivery postcode for review.
Do you support BWRO, ULP and SWRO membrane enquiries?

Yes. Crystwater can assist with brackish water RO, ultra-low pressure RO and seawater RO membrane enquiries for commercial and industrial 4040 and 8040 systems.
Can an RO membrane be replaced with a different brand?

In some cases, yes, but brand substitution should not be based on size alone. The replacement option should be reviewed against system design, feedwater quality, operating pressure, recovery rate, permeate quality requirements and site operating conditions.
What information should I provide for a quotation?

Please provide the existing membrane model, quantity, membrane size, application, feedwater type, feed TDS or conductivity, operating pressure, recovery rate, required permeate quality, preferred lead time and delivery postcode where available.
Can Crystwater support bulk or project-based RO membrane supply?

Yes. Crystwater can assist with bulk and project-based supply of commercial and industrial RO membranes, including 4040 and 8040 membrane elements. Pricing, lead time, freight basis and payment terms will be confirmed by quotation.
Can Crystwater provide a technical comparison between membrane options?

For project or bulk replacement enquiries, Crystwater can assist with a basic technical comparison between the specified membrane and alternative options to support engineering review.
Do you provide membrane performance guarantees?

Unless specifically agreed in writing, Crystwater supplies membrane elements and supporting technical documentation only. Actual RO system performance depends on feedwater quality, system design, pretreatment, operating conditions, cleaning practice and installation quality.
