Actual water production depends on feedwater quality, temperature, operating pressure and membrane condition.

Suitable Raw Water

The 2.5m³/h RO system can be designed to treat:

• • Municipal tap water

• • Borehole and well water

• • Low-salinity groundwater

• • Rainwater after suitable pretreatment

• • Pretreated river, lake or reservoir water

• • Industrial process water requiring further purification

The standard configuration is generally suitable for feedwater with TDS up to approximately 2,000 mg/L.

Water with higher salinity requires a customized BWRO design with suitable membranes, high-pressure pumps and pressure vessels. Learn more about our brackish water desalination systems.

A raw-water analysis is required when the water contains high hardness, iron, manganese, silica, suspended solids or organic matter.

 

Product-Water Quality

Under suitable design and operating conditions, the system can typically achieve:

• • Salt rejection of approximately 97%–99%

• • Significant reduction in TDS and conductivity

• • Substantial reduction in calcium and magnesium hardness

• • Reduced chloride, sulfate and other dissolved ions

• • Clear and stable product water

• • Consistent water quality for general industrial use

The actual product-water TDS depends on feedwater quality, membrane selection, recovery rate and operating conditions.

For drinking water, food production, laboratory use or boiler feedwater, the complete system must be designed according to the required water-quality standard. Additional disinfection, remineralization or polishing treatment may be necessary.

 

Typical Treatment Process

Standard Process

Raw Water → Raw-Water Tank → Feed Pump → Multimedia Filter → Activated-Carbon Filter → Softener or Antiscalant Dosing → 5μm Cartridge Filter → High-Pressure Pump → RO Membrane System → Product-Water Tank

Pretreatment is selected according to the raw-water analysis. Correct pretreatment helps control membrane fouling and scaling while maintaining stable RO performance.

Applications

The 2.5m³/h industrial RO system is suitable for:

• Small and medium-sized food and beverage factories

• Bottled-water plants and drinking-water stations

• Hotels, restaurants and commercial kitchens

• Cosmetic and personal-care production

• Laboratories and testing facilities

• Boiler makeup-water pretreatment

• Equipment and container washing

• Schools, offices and commercial buildings

• Rural communities and construction camps

• Small and medium-sized industrial production lines

Applications with specific chemical, sanitary or microbial requirements may require additional treatment and final water-quality testing.

 

Frequently Asked Questions

Does 2500L/H refer to feedwater or product water?

It refers to the rated RO product-water output. The required feedwater flow is higher and depends on the system recovery rate.

At 60% recovery, producing 2,500 L/h of purified water requires approximately 4,170 L/h of feedwater.

 

Can this system treat borehole water?

Yes. Pretreatment for sediment, hardness, iron and manganese will be selected according to the borehole water analysis.

 

What feedwater TDS can the system handle?

The standard configuration is generally suitable for feedwater with TDS up to approximately 2,000 mg/L. Higher TDS requires a customized brackish-water RO design.

 

Can the system operate continuously?

Yes. The system can support continuous automatic operation when properly sized with suitable raw-water and product-water storage. Routine inspection, filter replacement and membrane maintenance are still required.

 

Can the system use 220V single-phase power?

The power supply can be customized, but the final voltage and phase depend on the selected pumps and total electrical load. For a 2.5m³/h industrial system, three-phase power is generally preferred where available.

 

Can the product water be used for drinking?

The system can be configured for drinking-water production. Suitable disinfection and, where required, remineralization should be included. Final product water must be tested against applicable local standards.

 

How long do RO membranes last?

RO membranes typically operate for approximately two to four years, depending on feedwater quality, pretreatment performance, operating conditions and maintenance.

 

How much installation space is required?

The required space depends on the pretreatment vessels, tanks, pumps and optional equipment. A detailed general arrangement drawing will be provided after the final configuration is confirmed.
