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: email@example.com 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
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. Ask our team for help by emailing: firstname.lastname@example.org or clicking on our help page.
Organic or humic content on filters and membranes?
Cause: High organic content
Membrane damage leading to high salts passthrough and high flux?
Cause: Chlorine overdosing
Fix: Perform chlorine tests, check dosing equipment, redox meters, bisulfite levels and the general location of dosing equipment. Ask our team for help by emailing: email@example.com or clicking on our help page.
High Salt Passthrough?
Cause: Failure of the O-ring at the permeate tube
Bacteria and colloid fouling of micron-pre filters and membranes
Cause: Breakthrough of your media pre-filter
