Industrial RO Water Treatment Built Around Your Water Quality

There is no single reverse osmosis configuration suitable for every factory.

The HRO series is engineered according to your feed water quality, required product-water conductivity, production capacity and downstream process.

For standard process-water applications, a single-pass RO water treatment system may be sufficient. Projects requiring lower conductivity can use double-pass RO, while higher-purity applications can add EDI after the RO stages.

This modular approach allows the water treatment system to match the actual production requirement instead of adding unnecessary treatment stages.

Typical Reverse Osmosis Water Treatment Process

A complete industrial reverse osmosis water treatment system can be configured with:

Raw Water Tank → Raw Water Pump → Multimedia / Quartz Sand Filter → Activated Carbon Filter → Water Softener if Required → Security Filter → Reverse Osmosis → RO Water Tank → Second-Pass RO if Required → EDI if Required → Pure Water Tank → UV Sterilization / Ozone → Point of Use

Pretreatment

Pretreatment protects the RO membranes and improves system stability.

Depending on the feed water, the system may include:

• Multimedia or quartz sand filtration

• Activated carbon filtration

• Water softening

• Precision / security filtration

• Chemical dosing when required

Activated carbon treatment is especially important when chlorine must be removed before the RO membrane.

Reverse Osmosis

The RO membrane is the main separation stage of the system.

Under pressure, water passes through the reverse osmosis membrane while most dissolved salts and other impurities are retained and discharged with the concentrate stream.

The supplied HRO system can be configured with one or two RO stages depending on the target water quality.

Optional EDI Purification

For projects requiring higher-purity process water, electrodeionization (EDI) can be installed after the RO system.

EDI combines ion-exchange media with an electrical field to continuously remove remaining ionic contaminants. Unlike conventional ion-exchange regeneration, EDI can operate without routine acid and alkali regeneration.

This makes RO + EDI water treatment systems suitable for production lines where stable low-conductivity water is required.

Key Features of the HRO Industrial Reverse Osmosis System

1. Custom Capacity

The HRO series is not limited to one fixed production capacity.

Common project requirements can include:

250 L/H · 500 L/H · 1,000 L/H · 2,000 L/H · 3,000 L/H · 5,000 L/H · 10,000 L/H · 20,000 L/H and larger customized systems

Other capacities can be engineered according to required hourly or daily water consumption.

2. Flexible Water Quality

Choose from:

• Single-pass RO

• Double-pass RO

• RO + EDI

• RO + UV

• RO + ozone

• Customized combined treatment

The required system should be selected according to the final process rather than capacity alone.

3. Automatic Operation

Automatic configurations can use tank level signals to control pumps and system operation.

PLC and touch-screen control can also be configured according to project requirements.

4. Modular Equipment Configuration

Pretreatment, RO membranes, storage tanks, EDI, UV and other treatment modules can be configured according to the installation space and water quality requirement.

5. Material Options

Tank and piping configurations can be selected according to the application, including stainless steel and suitable industrial piping options.

6. Easy Production-Line Integration

Purified water can be transferred directly to:

• Vacuum emulsifying mixers

• Cream and lotion production tanks

• Shampoo and liquid soap mixing tanks

• Perfume preparation systems

• Storage tanks

• Other process equipment

HRO Industrial RO System Specifications

Important: Final water quality, recovery rate and operating parameters depend on feed-water quality, membrane selection and system configuration.

Water Treatment for Cosmetic and Personal Care Manufacturing

Water is one of the major raw materials used in many cosmetic and personal care formulations.

An appropriately configured RO water treatment system can provide purified process water for products such as:

• Creams

• Lotions

• Serums

• Shampoos

• Conditioners

• Shower gels

• Liquid soaps

• Facial cleansers

• Personal care liquids

• Perfume and fragrance processing

• Other water-based cosmetic formulations

The HRO system can be installed as an independent industrial water purification system or integrated with a complete cosmetic manufacturing line.

Which RO System Does Your Factory Need?

Single-Pass or Double-Pass Reverse Osmosis?

A single-pass reverse osmosis system is normally considered when the required product-water quality can be achieved after one RO membrane stage.

A double-pass reverse osmosis system processes the first-pass RO water through a second RO stage to further reduce dissolved ionic content.

The correct choice depends on:

• Feed-water conductivity

• Feed-water hardness and contaminants

• Required product-water conductivity

• Downstream manufacturing process

Do You Need RO + EDI?

EDI is usually considered when the required water purity is higher than the target achievable with the selected RO configuration alone.

The typical sequence is:

Pretreatment → RO → Second-Pass RO → EDI → Pure Water Storage

For cosmetic and industrial applications that do not require this level of purification, EDI may not be necessary.

HONEMIX can configure the system according to the actual water-quality target rather than automatically adding EDI to every project.

What Information Is Needed to Select an Industrial RO System?

To recommend the correct reverse osmosis water treatment equipment, please provide:

1. Feed water source
   Municipal water, groundwater or another source.

2. Feed water analysis
   TDS, conductivity, hardness, chlorine and other available water-quality data.

3. Required capacity
   For example, L/H, m³/H or total daily consumption.

4. Required purified-water quality
   Conductivity, TDS, resistivity or other process requirement.

5. Application
   Cream, lotion, shampoo, perfume or other industrial process.

6. Destination electrical standard
   Voltage, frequency and phase.

With this information, the pretreatment, RO stages and optional EDI configuration can be selected more accurately.

Why Use a Customized RO Water Treatment System?

Buying a larger RO system does not necessarily produce better water.

The correct system should balance:

Feed Water Quality + Required Water Purity + Required Capacity + Recovery + Downstream Process

For example, a factory with relatively clean municipal feed water and moderate conductivity requirements may only need pretreatment and single-pass RO.

Another project with higher feed-water conductivity or lower product-water conductivity requirements may require:

Pretreatment → Double-Pass RO → EDI

A project-specific configuration helps avoid both insufficient treatment and unnecessary equipment investment.

FAQ         

What capacity industrial reverse osmosis system can HONEMIX supply?

HRO systems can be customized according to the required hourly or daily water demand. Common capacities range from smaller industrial systems to high-flow customized installations. Tell us the required L/H or m³/H and we can configure the system accordingly.

Can the HRO system use double-pass reverse osmosis?

Yes. The system can be configured as either single-pass or double-pass RO depending on feed-water quality and the required purified-water specification.

Can EDI be added after reverse osmosis?

Yes. EDI is available as an optional polishing stage for projects requiring higher-purity water after RO treatment.

Do I need a water softener before RO?

Not every project requires the same pretreatment. A softener may be recommended when feed-water hardness creates scaling risk. The pretreatment configuration should be based on water analysis.

Can the system be customized for cosmetics manufacturing?

Yes. The HRO industrial RO water purification system can be configured for purified process water used in cream, lotion, serum, shampoo, liquid soap, perfume and other cosmetic or personal care manufacturing processes.

Can the RO system connect to existing production equipment?

Yes. Tank volume, piping connections, pumps and system layout can be configured according to the existing production area and downstream processing equipment.
