🔬
\n
Reverse Osmosis (RO)
\n
Removes 95–99% of dissolved contaminants
\n
\n
\n
Forces water through a semi-permeable membrane (0.0001 micron) under pressure, rejecting dissolved salts, heavy metals, bacteria, viruses, and most organic compounds.
High-pressure reverse osmosis specifically engineered for seawater (30,000–45,000 ppm TDS). Includes energy recovery devices, anti-scalant dosing, and multi-stage pre-treatment.
Uses ion exchange resins and electric current to continuously remove ionic contaminants from RO permeate. Produces 18 MΩ ultrapure water without chemical regeneration.

Chemical-free disinfection at 254nm
\n
\n
\n
Destroys bacteria, viruses, and microorganisms by disrupting DNA with ultraviolet light at 254nm. No chemical residuals, no taste/odor impact. Used as final polishing step or for system sanitization.
Hollow-fiber membranes that remove bacteria, viruses, colloids, and suspended particles without removing beneficial minerals. Used as RO pre-treatment to extend membrane life or as standalone purification.
Activated carbon adsorbs chlorine, chloramines, VOCs, and organic compounds that would otherwise degrade RO membranes. Multimedia filtration removes suspended solids, turbidity, and iron to protect downstream equipment.

Technology Questions
\n \n What water purification technologies does AMPAC USA use? +\n
Reverse osmosis, nanofiltration, ultrafiltration, UV sterilization, electrodeionization (EDI), activated carbon, and multimedia filtration. Most systems combine multiple technologies for complete treatment.
\n \n \n What is the difference between RO and ultrafiltration? +\n
RO (0.0001 micron) removes dissolved salts, heavy metals, and ionic contaminants. Ultrafiltration (0.01–0.1 micron) removes bacteria, viruses, and colloids but not dissolved salts. RO is used when low TDS output is required; UF is used for pre-treatment or when mineral retention is desired.
\n \n \n What TDS levels can AMPAC RO systems achieve? +\n
Commercial RO systems achieve 95–99% TDS rejection. Seawater systems typically output under 500 ppm from 35,000 ppm feed. RO combined with EDI achieves pharmaceutical-grade water below 1 ppm TDS.
\n \n \n Can AMPAC systems treat brackish water? +\n
Yes. Dedicated BWRO systems handle 1,000–10,000 ppm TDS at 150–300 PSI operating pressure — significantly lower energy than seawater systems. Ideal for well water, agricultural, and inland industrial applications.
