Seawater Reverse Osmosis Membrane: We are Chunke Water Treatment, an engineering and manufacturing team in Guangzhou focused on dependable seawater desalination system systems for worldwide reverse osmosis projects.
Our approach combines custom design, factory testing, and global delivery to meet strict production and quality targets.
At the heart of our product is the element that separates salt and delivers specification-grade water. We pair that element with robust pretreatment, ultrafiltration, and polishing trains to protect performance and uptime.
We design systems for vessels, offshore platforms, coastal industries, and municipalities so customers get reliable output under changing salinity and temperature.

Engineered SWRO Solutions for Reliable Desalination Across Industries
We tailor high-capacity element arrays and pretreatment so product water stays consistent under real feed conditions.
Where our systems excel:
Marine, industrial, and municipal applications
For marine projects we design compact frames for engine rooms and deck spaces. We use anti-corrosion materials and easy service access to limit fouling in harbors and marinas.
Industrial trains are sized to match process flow and recovery needs. We integrate skids with controls and utilities to fit existing plant layouts.
For municipalities we specify multi-train layouts with redundancy and standardized elements for simple operation and training.
From Guangzhou to the United States: rapid design, manufacturing, and shipping
Our Guangzhou factory compresses design/build cycles and coordinates export packaging, documentation, and timely shipping to US ports.
We cover design submittals, logistics, and installation guidance so commissioning runs smoothly and cost forecasts match expected lifecycle needs.
- Membrane life is typically 3–5 years with proper flushing and care.
- We advise strict controls on overboard discharge to avoid contaminant recirculation near intakes.
- We size pressure windows, cleaning intervals, and pretreatment to reduce fouling risk and downtime.
| Application | Key Design Feature | Typical Flow Range | Shipping/Delivery |
| Marine | Compact skid, corrosion resistance | 0.5–10 m3/hr | Sea freight to US ports; rapid crate handling |
| Industrial | Process-integrated trains, control integration | 5–500 m3/hr | Export packaging, on-time documentation |
| Municipal | Redundant multi-train layouts, instrumentation | 100–10,000 m3/day | Coordinated logistics and installation support |

Seawater Reverse Osmosis Membrane Performance, Salt Rejection, and Lifecycle Value
Performance drivers such as high-rejection chemistries and low-energy elements determine both output and operating expense.
High salt rejection and optimized flow: leveraging TFN and advanced chemistry
We specify TFN-based elements that deliver industry-leading salt rejection and up to 20% more flow versus conventional options. These gains translate into higher product yield or lower specific energy for the same operating window.
Lower energy demand and stable operation: dry, low-energy, and fouling-resistant element options
Our element portfolios include dry-start, low-energy, and fouling-resistant choices that slow pressure-drop increase and cut CIP frequency. That stability keeps salt passage steady even after repeated cleanings.
Membrane life, replacement cadence, and total cost of ownership
Membrane replacement can represent roughly 5% of the total cost of water and about 12% of operating cost. We model lifecycle scenarios so you choose elements and cleaning schedules that lower long-term cost.
| Feature | Benefit | Typical Impact | Example |
| TFN high-rejection | Higher salt rejection | Up to 20% more flow, better product quality | LG Chem NanoH2O portfolio |
| Dry / Low-energy elements | Lower handling and energy | Reduced standby losses, energy savings | DuPont FilmTec SW30XLE / Seamaxx-440 |
| Fouling-resistant | Stable pressure profile | Less frequent CIP, extended life | SW30XFR-400 series |
| Lifecycle planning | Optimized replacement cadence | Lower cost per m3, predictable OPEX | 40″ element price example: ~$549 |
Pressure, temperature, and feedwater quality: designing for consistent performance
We engineer arrays to match pressure and temperature ranges and specify pretreatment to limit organics and particulates. This stabilizes flow and rejection and reduces chemical use.
We design and manufacture complete systems, and we help customers select elements to hit target rejection while optimizing lifecycle cost.

System Design and Integration: RO, UF, EDI, and Pre Treatment Built Around Your Water
From intake to product water, we configure each stage so operators see clear controls and predictable output.
We start at intake by specifying screening and dosing to protect ultrafiltration and cartridge filters from large particulates. This stabilizes raw seawater quality before it reaches the membrane train.
Our pretreatment typically pairs ultrafiltration with filtration to cut turbidity and biofouling load. That improves downstream salt rejection stability and lengthens clean-in-place intervals.
- The core reverse osmosis section is modeled to your salinity, temperature, and product specs.
- Where ultra-low conductivity is needed, we add EDI as a polishing step after RO.
- Controls monitor pressure, flow, conductivity, and differential pressure for proactive maintenance.
| Stage | Key Feature | Benefit |
| Intake & Pretreatment | Screening, dosing, UF | Stable feed, reduced fouling |
| High-Pressure RO | Vessel arrays, element selection | Optimized salt rejection and pressure use |
| Polishing & Storage | EDI, remineralization, tanks | Consistent product water quality |
Documentation includes P&IDs, a reverse osmosis plant diagram, and O&M manuals to support commissioning and long-term reliability. Learn more about our ultrafiltration technology and review desalination options at our desalination plant options.
