What should the trial compare?
Keep feed water, concentration factor, pH, temperature, oxidant exposure, mixing and residence time representative. Compare dissolved and deposited mineral, suspended material, filtration and operating trends. Verify metal corrosion and long-term membrane compatibility as separate endpoints when they are relevant to the application.
Prepare a quotation
Send the product or model, required specification, quantity, packaging and destination. Include the application and current product, if known. Confirm the available TDS, SDS, batch documents, storage conditions and commercial delivery terms for the actual offer.
