Skid-Mounted BWRO Systems | 100–2,000 m³/day

100–2000 m³/day Brackish Water Desalination Systems

GlobalUF provides skid-mounted brackish water reverse osmosis (BWRO) systems for projects requiring 100–2,000 m³/day of RO permeate. Single-skid and modular multi-skid arrangements are developed around your feedwater analysis, required water quality, operating schedule and site layout.

From industrial process water to agricultural and community water projects, the treatment package is configured for the application—not selected on capacity alone.

What Is a Skid-Mounted BWRO System?

A skid-mounted BWRO system combines reverse osmosis equipment on a supporting frame to treat suitable brackish water. RO membranes separate the feedwater into a lower-salinity product stream, called permeate, and a concentrated reject stream, called concentrate.

A project may use one RO skid or several coordinated units. Pretreatment, chemical dosing, cleaning equipment and storage tanks may be installed separately, depending on the layout and agreed supply scope.

Capacity Range and Production Basis

The 100–2,000 m³/day range refers to RO permeate production, not raw-water intake. Daily production must be matched to the actual number of operating hours.

These are flow conversions for initial planning, not fixed model ratings or guaranteed net daily deliveries.

Required hourly permeate flow = required daily permeate volume ÷ actual production hours.

For example, a project requiring 1,000 m³/day over 20 production hours needs 50 m³/h of permeate. Final sizing must also account for the specified feedwater temperature and chemistry, maintenance downtime and any product water used internally.

The number of skids is determined by equipment dimensions, transport access, maintenance space and operating requirements. Capacity alone does not determine whether a system should use one skid or several.

Applications for Skid-Mounted BWRO

BWRO can be evaluated where dissolved salts in borehole water, groundwater or another suitable brackish source need to be reduced for a defined use. Industrial process-water treatment, food and beverage processing, and brackish-water desalination are established RO applications.

Drinking-water projects require assessment of the complete treatment, storage and distribution system. RO permeate is not automatically finished drinking water.

Treatment Process and Pretreatment Options

Pretreatment is selected from the water analysis rather than applied as the same package to every well. Different sources may require different measures for suspended solids, iron, manganese, hardness, organics or oxidants.

A reference treatment sequence is:

Feedwater → Project-Specific Pretreatment → Cartridge Filtration → High-Pressure Pump → BWRO → Application-Specific Post-Treatment → Product Water Storage or Distribution

This is an indicative process sequence, not a fixed equipment package.

These options are evaluated against the source water and selected process; they are not all required for every installation.

Ultrafiltration may be considered for particulate control before BWRO. UF does not replace RO for dissolved-salt removal.

Sulfate, silica and other scale-forming constituents must also be considered. A TDS result alone is not enough to define the pretreatment or system recovery.

Equipment Configuration and Technical Scope

The RO assembly can include cartridge filtration, a high-pressure pump, membrane pressure vessels and elements, piping, valves, flow and pressure instruments, and a local control panel. Dosing and clean-in-place (CIP) equipment are defined in the project scope and may be separate packages.

There is no universal membrane model, pressure, recovery rate or energy-consumption figure for the entire capacity range. The technical proposal and contract define the equipment and performance commitments for each project.

Single-Skid and Modular Multi-Skid Arrangements

Choose the arrangement around operation and maintenance, not only the daily capacity.

A single-skid arrangement groups the specified RO components on a common frame. It can be evaluated where the required equipment, access clearances and transport dimensions fit the project.

A multi-skid arrangement divides treatment capacity into separate units. Independently controlled units can support staged operation and planned servicing when the hydraulic and control design allows it.

Required backup capacity must be specified separately. Multiple skids do not automatically provide full plant output when one unit is offline.

Future expansion should also be considered during initial design. Feedwater availability, pretreatment, power supply, headers and drainage must be checked before adding further treatment units.

Skid-Mounted or Containerized BWRO?

Skid-mounted equipment is a practical option when the project has a suitable plant room or equipment shelter. It allows the RO equipment to be integrated with site-specific tanks, pretreatment and utilities.

A containerized BWRO system can be evaluated where an equipment enclosure forms part of the supply requirement. Container dimensions, equipment access, ventilation and environmental conditions still need to be addressed.

Both formats require site preparation, feedwater and product-water connections, power, drainage and commissioning. Neither format removes the need to define local responsibilities.

Equipment Supply, Engineering Support and Factory Testing

GlobalUF works with EPC contractors, local system integrators and end users on equipment supply, OEM cooperation and project-specific engineering support.

The agreed package can cover the RO skids and selected pretreatment, dosing, CIP and control equipment. Documentation requirements—such as layout drawings, equipment schedules, operating instructions and interface information—should be established with the supply scope.

Factory Acceptance Testing

Factory acceptance testing (FAT) is defined for the project. The agreed procedure may cover assembly checks, leak testing, control and alarm functions, and operating tests under documented conditions.

Test-water composition, temperature, operating conditions and acceptance criteria should be stated. A factory test using different water from the project source does not establish identical performance on site.

Site Preparation and Commissioning

Before shipment, the project team should confirm foundations or equipment supports, delivery and lifting access, maintenance clearances, feedwater supply, electrical connections, product-water storage, concentrate handling and chemical arrangements.

Civil works, external piping and cabling, installation supervision, commissioning and operator training must be identified in the quotation. Overseas equipment supply does not automatically include a complete turnkey installation.

BWRO Project Reference: Hill Group, Tanzania

GlobalUF’s published Hill Group project describes a borehole-water BWRO configuration with 12 m³/h of combined capacity, arranged as two 4 m³/h units and two 2 m³/h units.

This reference illustrates a project-specific modular arrangement using different unit capacities. Its configuration is not a standard design or a performance guarantee for other feedwater conditions.

Frequently Asked Questions

Can BWRO treat salty borehole water?

Yes, BWRO can be evaluated for suitable saline borehole water. A complete analysis is needed to assess salinity, hardness, iron, manganese, silica and other relevant constituents. The water source and target use determine the treatment package.(Learn more from Dupont)

Can a 2,000 m³/day system fit on one skid?

Not necessarily. The operating schedule determines the hourly flow, while component dimensions, transport restrictions and maintenance access determine the layout. A 2,000 m³/day project may require several skids or treatment units rather than one frame.

What recovery rate can the system achieve?

Recovery is determined for each project. Water chemistry, scaling potential, fouling risk, pretreatment and membrane operating limits must be assessed together. GlobalUF does not assign one recovery rate to every BWRO system based only on feedwater TDS.

Can the permeate be used directly as drinking water?

Not automatically. Drinking-water use requires assessment of the applicable water-quality requirements and the complete treatment chain. Depending on the project, pH adjustment, remineralization, disinfection and suitable storage and distribution may be needed.

Can BWRO be used before a high-purity water system?

Yes. RO can form part of a high-purity treatment train. A second RO pass, electrodeionization or other polishing may be required according to the final specification. A BWRO skid alone should not be treated as a complete high-purity water system.(Learn more from Dupont)

How much does a skid-mounted BWRO system cost?

The quotation depends on capacity, feedwater quality, pretreatment, materials, controls, documentation and the installation or support scope. Freight and destination requirements also affect the delivered project cost. A comparable quotation needs a defined design basis and supply boundary.
