Industrial Reverse Osmosis System | Beta Pramesti Asia
Betaqua industrial RO units treat brackish water or seawater at 0.2–100 m³/h. Compare feed analysis, permeate targets, recovery, pretreatment and CIP.
The Betaqua industrial reverse osmosis system from PT Beta Pramesti Asia treats brackish water or seawater to produce permeate for utilities and process use. Units on this page cover 0.2–100 m³/h; final sizing must follow feedwater analysis, permeate targets, recovery, pretreatment, and the concentrate-disposal route.
PT Beta Pramesti Asia supplies RO packages with cartridge filtration, pressure pumps, flow and pressure instruments, PLC control, autoflush, and model-dependent antiscalant dosing and CIP. Complete design data prevents a project from selecting equipment on nominal capacity alone.
The FilmTec RO/NF technical manual, revised February 2026 likewise treats feedwater analysis and pretreatment as design inputs. Catalogue capacity therefore needs to be read with the flow balance, recovery, permeate specification, scaling and fouling risk, and the limits of the membrane ultimately selected.
Data needed to select an industrial reverse osmosis system
| Project data | Why it matters |
|---|---|
| Permeate flow and operating hours | Sets unit capacity and standby requirements |
| Feedwater analysis | Establishes pretreatment, recovery, and scaling or fouling risk |
| Required permeate quality | Determines single-pass, double-pass, or polishing configuration |
| Concentrate-disposal route | Confirms that the water balance and reject stream are workable |
| Space, power, and controls | Defines layout, electrical load, instrumentation, and plant integration |
What should an industrial RO quotation make explicit?
An industrial RO quotation should let the project team compare capacity, supply scope, utilities, and performance acceptance on the same basis. Ask for the design assumptions and exclusions in writing so a feedwater change or a tighter permeate target is not hidden behind one nominal-flow number.
| Quotation section | Items to state |
|---|---|
| Design basis | Water analysis, temperature, feed flow, permeate flow, operating hours, recovery, product quality, and expected variability |
| Process scope | Pretreatment stages, pass and train count, membranes, pumps, vessels, cartridge filters, dosing, CIP, and concentrate route |
| Utilities and integration | Power, inlet pressure, service space, drains, chemical storage, piping materials, control signals, and battery limits |
| Performance acceptance | Test-feed condition, permeate parameters, flow, recovery, pressure, test duration, baseline data, and deviation handling |
| Post-handover operation | Manuals, training, initial spares, instrument calibration, monitoring schedule, CIP triggers, and support data |
Evaluate RO antiscalant, membrane cleaning chemicals, and dosing pumps with the unit design. For membrane replacement and components, see industrial reverse osmosis membranes and systems at Watermart. Send the water analysis, capacity, and product-water target through the Beta contact page.
Which industrial RO system fits the project?
Feedwater type and the permeate specification determine whether the project evaluates BWRO, SWRO, single-pass, or double-pass treatment. Nominal capacity must still be checked against recovery, concentrate flow, train count, pretreatment, power, materials, and service space.
| Project need | Configuration to evaluate | Checks before selection |
|---|---|---|
| Brackish water or a saline raw-water source | Brackish Water Reverse Osmosis (BWRO) | Ion analysis, scaling risk, turbidity/SDI, permeate target, recovery, pressure, and concentrate route |
| Seawater | Seawater Reverse Osmosis (SWRO) | Salinity, temperature, pretreatment, high pressure, materials, energy demand, and concentrate disposal |
| Tighter permeate specification | Single pass with polishing or a double-pass configuration | Conductivity and product parameters at each stage, recovery balance, and any degassing or EDI/mixed-bed requirement |
| Critical or variable-flow operation | Multiple trains, turndown, or standby capacity | Flow profile, capacity with one train offline, controls, spares, and the cleaning plan |

Use the industrial reverse osmosis application guide to prepare feedwater analysis, permeate targets, the recovery balance, pretreatment, and a concentrate route before requesting a system proposal.
When RO is being evaluated for reuse, start with the water-conservation guide for communities and industry so the opportunity follows the water balance and the quality required for the next use.
FAQ
What is the difference between BWRO and SWRO systems?
BWRO is intended for brackish water or raw water with lower salinity, while SWRO treats seawater and requires different pressure, energy, pretreatment, materials, and concentrate evaluation. Final selection must follow the feedwater analysis and permeate target.
Is nominal capacity enough to select an industrial RO system?
No. Read permeate capacity with operating hours, recovery, feed and concentrate flow, water quality, fouling or scaling risk, temperature, train count, and the capacity available during cleaning or maintenance.
What data is needed for an industrial RO proposal?
Provide a complete water analysis, source and temperature, permeate flow, operating hours, quality target, concentrate route, power conditions, available space, existing pretreatment, redundancy needs, and the installation and commissioning boundary.
