KSRO Series RO System – Ultra-High Flow Reverse Osmosis

Product Overview

The KSRO Series RO System is an advanced reverse osmosis solution designed for industrial and commercial water purification. Built on the KISS (Keep It Simple Stupid) principle, this system delivers high flow, dependable performance, and minimal maintenance. The fixed recovery rate is 60-65%, and it features ROTEK’s “Pulse Flush” technology to help reduce fouling and enhance membrane lifetime.

Key Features & Benefits

  • One-button operation makes the KSRO Series RO System easy to use across industrial setups.
  • Automatic high-frequency Pulse Flush design eliminates the need for manual concentrate regulation.
  • Uses a single extra-large XL-4040 membrane, delivering 4000 GPD (650 LPH) of permeate.
  • Fixed recovery rate (≈ 60-65%) ensures water efficiency.
  • Skeletal frame: stainless steel (SS304) skid frame, 300 PSI membrane housing with PE end caps.
