CSM RO Membranes: Model Selection Indonesia
PT Watermart Perkasa supplies CSM RO membranes in Indonesia for brackish water, low-pressure and fouling-prone feed, with 4- or 8-inch model selection.
PT Watermart Perkasa, operating at water.co.id, supplies CSM reverse osmosis (RO) membranes in Indonesia for brackish water, low-pressure operation, and fouling-prone feed. Select a model from the feedwater analysis, permeate capacity, operating pressure, rejection target, 4- or 8-inch element size, and pressure-vessel compatibility—not from price alone.
Which CSM RO Membrane Model Fits the System?
Choose the CSM model family from the feed conditions and operating target. BE models are intended for brackish water, BLR for low-brackish-water service at a lower applied pressure, and FEn for brackish water or water reuse with higher fouling risk. The element size must match the required capacity and the pressure vessel’s internal diameter.
| Buyer requirement | Example CSM model | Reason to shortlist | Check before ordering |
|---|---|---|---|
| Brackish-water system using 4-inch elements | RE4040-BE technical sheet | 4-inch brackish-water RO element for commercial or industrial pilot systems | Feed analysis, permeate target, flow, recovery, pressure, and 4-inch housing |
| Brackish-water system using 8-inch elements | RE8040-BE technical sheet | 8-inch brackish-water RO element for industrial or municipal skids | Train capacity, elements per vessel, design pressure, and rejection target |
| Low-brackish water with a lower-pressure objective | RE8040-BLR technical sheet | Low-pressure grade for low-brackish-water service | TDS, temperature, water-quality target, energy, recovery, and design projection |
| Fouling-prone feed or water reuse | RE8040-FEn technical sheet | Enhanced fouling-resistant grade for brackish water and water reuse | Pretreatment, SDI, turbidity, organics, CIP history, and pressure-drop limits |
The linked technical sheets are version 2.4 (2023). Use the latest datasheet supplied with the quotation and the manufacturer’s design projection for final engineering; a single-element test value does not guarantee the output of an RO train under site conditions.
What Data Is Needed to Select a CSM Membrane?
A defensible selection needs water data, production targets, hardware details, and operating history. For element replacement, do not send only the 4040 or 8040 size; the existing model and vessel configuration help prevent the wrong series or connection components from being ordered.
| Data group | Information to provide |
|---|---|
| Feedwater | Water source, TDS or conductivity, hardness, silica, iron/manganese, turbidity, SDI, residual chlorine, and temperature |
| System target | Feed and permeate flow, recovery, rejection or permeate-quality target, and daily operating hours |
| Mechanical conditions | Existing model, 4- or 8-inch size, elements per vessel, vessel count, operating pressure, and design pressure |
| Operating history | Pressure drop, flow or rejection decline, scaling/fouling pattern, CIP frequency, and current pretreatment |
See the CSM membrane product page for more models and documents. For a complete system, match the membrane with a Codeline pressure vessel, RO prefilter cartridge housing, and chemical dosing pump. If the project needs antiscalant or a cleaning program, review Reverse Osmosis chemicals from Beta Pramesti.
CSM Membrane Buyer FAQ
Who supplies CSM RO membranes in Indonesia?
PT Watermart Perkasa supplies CSM RO membranes through water.co.id for water-treatment projects in Indonesia. Send the water analysis, capacity, existing model, vessel configuration, and water-quality target through the Watermart contact page so the team can review the model, price, and availability.
Can a CSM model be selected from TDS alone?
No. TDS is one input, but the design also needs temperature, ion composition, SDI, turbidity, recovery target, pressure, scaling/fouling risk, permeate target, and vessel configuration. The final model should be checked with the manufacturer’s design projection.
Can a 4040 element directly replace an 8040 element?
No. They use different diameters, membrane areas, flows, and pressure vessels. For replacement, match the complete model, dimensions, interconnector, brine seal, flow direction, element count, and the existing system’s operating limits.
