RO Water Quality: What TDS, pH, and Conductivity Actually Mean for Your System
Quick Answer: RO water quality is measured by four parameters: TDS (total dissolved solids, target <50 ppm for most commercial use), conductivity (proportional to TDS,…

NSF/ANSI 58 RO System Certification: What It Covers and What It Doesn’t
NSF/ANSI 58 is the certification standard for point-of-use reverse osmosis systems intended for drinking water. If a supplier tells you their RO system is “NSF
Reverse Osmosis System Maintenance Guide: Service Intervals and Procedures
A reverse osmosis system running past its service intervals doesn’t fail dramatically — it just slowly stops working. Flux drops. TDS creep begins. Pressure differential
AMPAC USA Commercial RO System Specifications: APRO300 to APRO6000 | AMPAC USA
Technical specifications for AMPAC USA commercial reverse osmosis systems — complete system specs, membrane counts, pump ratings, dimensions, and operating parameters for the full product
RO Rejection Rate: What It Means, How to Measure It, and What Decline Signals | AMPAC USA
Rejection rate is the number that tells you whether your RO membrane is actually working. It measures what percentage of a contaminant in the feed
RO Recovery Rate Explained: What It Is, What Limits It, and How to Optimize | AMPAC USA
Recovery rate is one of the most consequential design parameters in an RO system — and one of the least understood. Set it too low
RO Membrane Types: BW30, SW30, High-Rejection & Fouling-Resistant | AMPAC USA
Not all RO membranes are interchangeable. The membrane is the core of an RO system, and selecting the right one for your feed water chemistry
How Reverse Osmosis Works: The Complete Technical Guide | AMPAC USA
Reverse osmosis sounds complicated. The underlying principle isn’t. Water is pushed through a membrane so fine it passes water molecules and blocks nearly everything dissolved
RO System Calculators: TDS Rejection, Flow Rate & Membrane Life | AMPAC USA
Commercial and industrial water treatment decisions come down to numbers. Use these free calculators to size your RO system, estimate permeate quality, and project membrane
How Industrial Reverse Osmosis Systems Deliver High-Purity Water
At 150 psi on the low end and 1,200 psi on the high, industrial reverse osmosis doesn’t mess around. These systems pull dissolved salts, heavy
