WTT INTERNATIONAL company logo for RO90 high-recovery reverse osmosis system

Compact Reverse Osmosis System

Industrial-Grade Purification Engineered Into A Plug-And-Play Skid That Fits Almost Anywhere. Achieve 90% recovery with advanced concentrate recirculation technology.

RO90 Advanced Control Panel with HMI
1 / 5

The Challenge With Conventional RO

Scaling, Excessive Reject And Multi-Skid Footprints Drive Cost And Downtime, Especially On Variable Brackish Or Wastewater Feeds. Traditional RO systems struggle with high recovery rates due to concentration polarization and scaling issues.

Tackles All Three Pain Points In One Compact Platform And Delivers 90% Recovery.

What Makes Different

Dual-Chemical Conditioning
Separate Acid And Antiscalant Streams Suppress Carbonate And Non-Carbonate Scales Before They Form.
Low-Fouling (LD) Spiral Membranes
Dual-Stage Array Maximises Salt Rejection While Limiting Concentration Polarisation.
Integrated Concentrate Recirculation
Metered Slipstream Returns To Feed; No Booster Pump, Enabling Stable 90% Recovery.
Live Diagnostics
In-Line pH, Pressure Transmitters And Three Rotameters Feed A PLC/HMI For Real-Time Visibility.
Micro Footprint
Straight-Through Hydraulics And One High-Pressure Pump Keep The Entire Skid Below 2 m² At 100 KLD Rating.
