4,000 Sea Water RO Plant

A 4,000 Sea Water RO Plant can produce 4,000 gallons of purified water per day (GPD). It has a flow rate of 72 cubic meters at 25 degrees Celsius and can reject up to 95-98% of impurities and salt from seawater, with a recovery rate of 50-60%.

The plant features a CSM RO membrane brand (8040 (400 sq. ft) x1 pcs) and an FRP RO pressure vessel (8040×1 pcs). The system also includes a 4 kW x 380V x 50 Hz Grundfos high-pressure pump (model CRI 5-29) with a 5T/hr flow rate and a lift head of 165M.

Other components of the 4,000 Sea Water RO Plant include a Pre-filter TK 7-20, pure water flow meter and drain flow meter, low-pressure and high-pressure valves, an RO frame made of stainless steel welding, and all pressure displayed on the main panel. The high-pressure components are made of SUS304, while the low-pressure pipe is # 80 UPVC. The system also features a flush, feed, and adjust the valve.

Regarding the price range in Dirhams for Dubai UAE, the cost of a 4,000 Sea Water RO Plant can vary based on several factors, such as the plant capacity, the quality of the components used, and the complexity of the installation. The price can range from AED 500,000 to AED 1,500,000, including installation and maintenance costs. The final cost may also depend on the supplier and the availability of financing options.

Overall, the 4,000 Sea Water RO Plant is an efficient water treatment system capable of producing a large quantity of purified water. Its high-quality components, including the CSM RO membrane, FRP RO pressure vessel, and Grundfos high-pressure pump, make it a reliable and effective solution for producing clean and safe drinking water.

What This System Does?

The 4,000 GPD Sea Water RO Plant is designed to desalinate seawater by reducing dissolved salts and other impurities through the reverse osmosis process. It is suitable for marine, commercial, industrial, and remote water supply applications where seawater is the available feedwater source.

Each seawater RO plant is engineered for site conditions and configured based on feedwater analysis, required permeate quality, daily water demand, and operating requirements. Pretreatment, operating pressure, and recovery are selected during system design and verified during commissioning.

How It Works

Seawater first passes through the pretreatment stage to reduce suspended solids and help protect the reverse osmosis membranes from fouling and scaling. A high-pressure pumping system then delivers the seawater through the RO membranes, separating it into permeate and concentrate streams.

The treated permeate is collected for storage or post-treatment, while the concentrate is discharged according to the system design. Pressure indicators, flow meters, and control valves assist operators in monitoring system performance during operation.

Frequently Asked Questions

What type of water can the 30,000 GPD RO plant treat?

This system is designed for brackish water applications. The final configuration depends on feedwater analysis, which determines the appropriate pretreatment process and membrane selection.

Is pretreatment required before the RO plant?

Yes. Pretreatment is selected according to feedwater quality and may include multimedia filtration, activated carbon filtration, water softening, cartridge filtration, or chemical dosing to help reduce membrane fouling and scaling.

Can the RO plant operate continuously?

The system is designed for continuous operation when operated within its design parameters and maintained according to the recommended service schedule.

Can this RO plant be customised for specific industrial applications?

Yes. The system can be configured based on production capacity, feedwater quality, installation conditions, and process water requirements to suit individual project needs.

What maintenance does the RO plant require?

Routine maintenance includes monitoring operating pressures, flow rates, conductivity, and replacing consumable components as required. Membrane cleaning and periodic system inspections help maintain reliable performance.
