1 T/H Fully Enclosed Water Purification Commercial RO Systems
This fully enclosed, cabinet-type water treatment system is engineered for a rated permeate flow of 1 m³/h (1,000 L/h), built for scheduled and non-continuous operation. Housed in a 304 stainless steel cabinet with lockable doors and mobile casters, the unit integrates pre-treatment and reverse osmosis (RO) into a single, compact footprint.
The standard 4-stage configuration combines quartz sand filtration, activated carbon adsorption, PP cartridge filtration, and RO. A simplified 2-stage configuration (PP cartridge + RO) is available for good-quality municipal feed water, while pre-treatment can be further customized for challenging source water.
An integrated pressure tank stabilizes system pressure and delivers purified water on demand, while the intelligent RO controller with digital display, pressure gauges, and rotameters provides real-time monitoring and fully automated operation. The enclosed design protects all internal components from dust, moisture, and unauthorized access, making it suitable for installation in public areas, kitchens, and production floors.
Perfect for facilities with fixed daily operating hours—such as cafes, restaurants, schools, small workshops, laboratories, and boiler feed systems—the system ensures reliable, high-quality water whenever it is needed.

Filtration Configurations
Standard 4-Stage: Quartz Sand → Activated Carbon → PP Cartridge → RO
| Stage | Process | Function |
| 1 | Quartz Sand Filtration | Removes suspended solids, sediment, rust, and large particulates to protect downstream components and prevent clogging. |
| 2 | Activated Carbon Filtration | Eliminates chlorine, organic compounds, unpleasant tastes, odors, and residual color, improving water aesthetics and protecting the RO membrane from oxidation. |
| 3 | PP Cartridge Filtration (5 μm) | Polypropylene precision filter removes fine particulates as the final polishing stage before RO, protecting the membrane from fouling. |
| 4 | Reverse Osmosis (RO) | The core purification stage, removing up to 98% of dissolved salts, heavy metals, bacteria, and viruses, producing high-purity water suitable for drinking, laboratory use, and industrial processes. |
⚙️ Optional 2-Stage: PP Cartridge (5 μm) → RO
For applications with good-quality municipal tap water, the system can be configured without sand and carbon tanks, reducing footprint and maintenance while maintaining full RO purification performance.
⚙️Customizable Pre-Treatment
For feed water with high hardness, iron/manganese, or other specific contaminants, additional stages such as ion-exchange softening, iron removal filters, or antiscalant dosing can be integrated into the cabinet.
Technical Specifications
| Parameter | Specification |
| Rated Permeate Flow Rate | 1 m³/h (1,000 L/h) |
| Operation Mode | Scheduled / On-Demand (Non-24/7) |
| Filtration Stages | 4-stage standard (Sand → Carbon → PP → RO); 2-stage (PP → RO) optional |
| PP Cartridge Rating | 5 μm |
| RO Rejection Rate | ≥98% (TDS) |
| Filter Tank Material | FRP (pre-treatment) / 304 Stainless Steel (cabinet & frame) |
| Pressure Tank | Integrated, built-in |
| Control System | Intelligent RO Controller + Digital Display |
| Operating Pressure | 0.7–1.0 MPa (RO section) |
| Power Supply | 220V / 380V, 50/60Hz (Customizable) |
| Mobility | Lockable caster wheels |
| Certification | CE Compliant |
Note on feed water hardness: Standard configuration relies on RO membrane rejection for hardness removal. For inlet hardness above typical municipal levels, an optional ion-exchange softener or antiscalant dosing system is recommended to prevent membrane scaling.
Key Features
Fully Enclosed Cabinet Design
Lockable 304 stainless steel doors protect all internal components, ensuring a clean, professional appearance and safe operation in public or shared spaces.
All-in-One Integration
Pre-treatment and RO combined into a single cabinet skid—no separate tanks or complex field piping required.
Two Configurations Available
Standard 4-stage (Sand + Carbon + PP + RO) for varied source water; simplified 2-stage (PP + RO) for good-quality municipal water.
Customizable Pre-Treatment
Stages can be added or removed based on feed water analysis—softening, iron removal, or antiscalant dosing available for challenging water.
Built-In Pressure Tank
Integrated pressure storage stabilizes system pressure and provides immediate purified water on demand, reducing pump cycling and extending equipment service life.
Optimized for Non-Continuous Use
Scheduled/on-demand operation with automated backwashing and membrane flushing cycles that run during off-peak hours.
Industrial-Grade Build
304 stainless steel cabinet and frame with FRP filter tanks and corrosion-resistant RO wetted components for long service life.
Smart Automation
Intelligent RO controller with digital display, flow metering, pressure monitoring, and fault alarms for set-it-and-forget-it operation.
RO Performance
High-efficiency RO membranes deliver consistent permeate quality, with options for brackish water or tap water feed.
Low Maintenance
Simple, robust design minimizes routine maintenance, ideal for users without dedicated water treatment staff.
