Scan the headlines below for common symptoms, causes, and solutions to water filter failures. If you have questions about your water quality or your water treatment system, please don’t hesitate to reach out to our professional water testing team.

Scale forming on the membrane?

Cause: Failure of the antiscalant, acid dosing device, or pH monitor

Fix: Check your dosing equipment is working properly and monitor all changes in water quality before and after the RO system. Ask our team for help by emailing: hello@simplewater.us or clicking on our help page.

Iron accumulation on the filters and membranes?

(Leading to a high pressure difference and low permeate flow)

Cause: High iron content in raw water, corroding pipes, failure of media filters

Fix: Check pipes and media filters. Ask our team for help by emailing: hello@simplewater.us or clicking on our help page.

Bacterial film on filters and membranes?

(Leading to high pressure difference and low permeate flow)

Cause: Ineffective sanitization or biocide

Fix:  Sanitize all filters, perform microbiological analysis, check chemical dosing tanks; heck for biocide adsorption on carbon filters, check contact times and dose rates, select broad-spectrum biocide for organic content.

High Salt Passthrough?

Cause: Failure of the O-ring at the permeate tube

Fix: Check conductivity in each vessel and membrane. Ask our team for help by emailing: hello@simplewater.us or clicking on our help page.

Bacteria and colloid fouling of micron-pre filters and membranes
