Input TDS Limit: Less than or equal to 2000 ppm for brackish configurations.

Free Chlorine: Less than 0.1 ppm maintained via carbon or bisulfite treatment.

Silt Density Index: SDI 15 less than 3 to prevent membrane fouling.

Hardness & pH: Hardness less than 5 grains per gallon; pH range 3.0 to 10.0 for operation.

Output Water Performance

Permeate Conductivity: Less than 10 microSiemens per centimeter using municipal tap water feed.

Heavy Metal Reduction: Greater than or equal to 99.0% removal for lead, cadmium, and chromium.

Microbial Elimination: 99.9% reduction of bacteria, viruses, and pyrogens.

Stabilized Rejection: 98% TDS removal efficiency at 25 degrees Celsius.

Optional Upstream & Downstream Add-Ons

Frequently Asked Questions

Q: How often should RO membranes be replaced?

A: With proper pretreatment maintenance and cleaning cycles, commercial RO membranes operate effectively for 2 to 4 years.

Q: What maintenance is required for continuous operation?

A: Routine tasks include monitoring pressure differentials, replacing pre-filter cartridges monthly, calibrating sensors, and executing Clean-In-Place procedures when flow drops by 10-15%.

Q: How is wastewater managed?

A: The reject stream is routed to facility drainage or reclaimed for non-potable greywater applications like irrigation or floor washing, complying with local codes.

Q: Can the system handle high-salinity well water?

A: Yes, provided feed water parameters are fully analyzed to engineer specialized high-rejection membranes and high-pressure pumps.
