HIGH RECOVERY REVERSE OSMOSIS

High-Recovery RO · More Water, Less Waste

More Water.
Less Concentrate.

Lower Costs · More Reuse · Less Concentrate

Upgrade existing RO, recover more from RO concentrate, or reduce feed to ZLD / MLD treatment. Designed for your site.

YOUR CURRENT RO

What Could Your RO Do Better?

Start with your site’s key challenges.

Lower Operating Costs

Reduce energy and membrane costs

Reduce Concentrate

Less concentrate to handle or dispose of

Recover More Water

More product water from the same feed

Support ZLD / MLD

Reduce downstream treatment demand

Recover RO Concentrate

Extract more water from existing RO concentrate

Why Choose HRRO?

Conventional RO recovers water. HRRO can go further.For sites seeking higher recovery with less concentrate and lower operating costs.

HOW TO APPLY

Where HRRO Fits Your Site

Choose the right configuration for your site—without assuming a full replacement.

Upgrade or Build New

Designs matched to feedwater, capacity and recovery goals.

Recover Existing RO Concentrate

Recover more water without replacing the entire RO system.

Before ZLD / MLD Treatment

Reduce the volume sent to concentrators and evaporators.

WATER BALANCE EXAMPLE

More Water. Less Concentrate.

Example: 75% vs. 90% recovery.

Conventional RO75% Recovery

Product Water 75Concentrate 25

HRRO90% Recovery

Product Water 90Concentrate 10

Up to ~95% recovery may be possible, depending on feedwater and operating conditions.

ZLD / MLD

Less Concentrate. Less ZLD / MLD Load.

For ZLD / MLD, HRRO can recover more water before concentration or evaporation, reducing the volume requiring thermal treatment.

MLDMinimal Liquid Discharge

Minimizes liquid wastewater discharge.

ZLDZero Liquid Discharge

Aims to eliminate liquid wastewater discharge.

ECONOMICS

Compare Total System Costs

A like-for-like scenario: equal product-water output, four cost indicators.

Wastewater Volume10,168 → 2,722 m³/day~73% less

CAPEXKRW 50B → 40B~20% less

Annual Electricity Use7,650 → 5,572 MWh~27% less

Membrane ReplacementKRW 500M → 250M/yr~50% less

Scenario BasisEqual product-water output

UF 95% (Both)·Conventional RO 75%·HRRO 95%

Illustrative estimates at equal product-water output. Wastewater includes UF and RO concentrate. Actual results depend on feedwater, capacity, recovery and design.
* The ~30%+ energy figure is a separate design estimate, not the ~27% annual-electricity result above. It depends on water quality, recovery, membrane selection and pump efficiency.
