Reverse Osmosis
High-rejection membrane separation for dissolved salts and many other contaminants.
Safety boundary: this guide is conceptual. It does not provide chemical dosing recipes, pressure-system procedures, wastewater-entry instructions, UV/ozone exposure procedures, electrical work or machine operating settings.
What this topic covers
High-rejection membrane separation for dissolved salts and many other contaminants.
Core water-treatment ideas
RO uses a semi-permeable membrane to separate permeate from a concentrated reject stream.
Pretreatment protects membranes from suspended solids, scaling, fouling and chemical damage.
Recovery, rejection and concentrate management must be considered together.
Important limits
MF/UF and NF/RO address different size ranges and dissolved-contaminant problems.
What to monitor
Pretreatment, fouling, integrity and concentrate management are core lifecycle issues.
Lifecycle perspective
High-pressure membrane operation and cleaning require manufacturer and professional procedures.
