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.

Technical Specifications

Standard Components

• 20″ – 5 micron sediment pre-filter
• Micro-computer controller with permeate TDS readout
• Rotameters for the permeate stream, and pressure gauges for the pre-filter and RO feed
• Danfoss low-pressure switch

Optional Add-Ons

• FRP membrane vessel
• Wireless / IoT controller (e.g., Oasis WiFi RO Controller)
• Variant without membrane
• Custom branding options

Applications & Use Cases

• Commercial water plants need 650 LPH of pure water.
• Industrial processes where TDS is ≤ 1000 ppm.
• Projects requiring high throughput with minimal maintenance.

Maintenance & Operational Notes

• Use the Pulse Flush function regularly to avoid membrane fouling.
• Monitor TDS in the permeate stream to ensure water quality.
• Replace the sediment pre-filter every 4-6 months, depending on feed water quality.
• Check pump pressure and inlet water conditions; feed pressure too low or too high can affect performance.
