Reverse Osmosis Systems

1. What are reverse osmosis systems?

Industrial Reverse Osmosis Systems are integrated, modular water purification units centered on polymer reverse osmosis membrane separation technology. Specifically engineered for source waters such as municipal tap water, groundwater from wells, surface water from rivers and lakes, and mildly brackish water, these systems employ a purely physical purification process throughout—requiring no chemical additives. They efficiently filter out dissolved salts, heavy metal ions, microorganisms, colloids, residual chlorine, and other harmful substances from the water, serving as core specialized equipment for the production of pure or purified water in industrial manufacturing, centralized water supply, and water recycling applications.

Applicable Scenarios

This reverse osmosis systems are suitable for use whenever production water purity falls below standard, tap water contains excessive impurities or hardness, or groundwater exhibits elevated TDS levels—specifically in cases where the raw water TDS ranges from 200 to 10,000 ppm (covering the typical range for standard water sources) and conventional filtration equipment is unable to meet the required water quality standards. It is particularly well-suited for industrial facilities, residential communities, and construction sites that lack a dedicated high-purity water supply or experience significant fluctuations in water quality. Designed to address critical requirements—such as water for production processes, drinking water supply, and environmental water recycling. The RO system is capable of generating water continuously and stably for 20 hours at a time, thereby meeting a wide range of purity standards for various applications.

2. What does a reverse osmosis system consist of?

The Reverse Osmosis system features an integrated, modular design. Its core components are sourced exclusively from leading industry brands—strictly vetted to ensure quality—and contain absolutely no generic or inferior parts. This ensures full quality traceability and provides a reliable foundation for after-sales support. The core components are detailed as follows:

• Raw Water Boosting Unit: Comprising a Lingxiao self-priming centrifugal pump, a stainless steel filtration valve, a pre-filter screen, and a vibration-dampening base. This unit ensures stable raw water delivery and is specifically adapted for water sources characterized by low pressure or high impurity levels, offering exceptional clog resistance and durability.
• Pre-treatment Purification Unit: Consisting of a quartz sand mechanical filter, a coconut shell activated carbon filter, a precision security filter, and an intelligent dosing system for scale inhibitors or reducing agents. This unit performs deep removal of sediment, odors, residual chlorine, and hardness ions (calcium and magnesium), thereby protecting the core membrane elements.
• High-Pressure Power Unit: Featuring a CNP Pump Industry stainless steel multi-stage high-pressure pump, a variable frequency control cabinet, pressure sensors, and a high/low-pressure interlock protection system. This unit precisely generates the pressure required for reverse osmosis, while ensuring energy efficiency, low noise levels, and smooth operation.
• Core Filtration Unit: Equipped with Time-Waterton anti-fouling RO membranes, FRP (fiberglass-reinforced plastic) membrane housings, membrane support racks, and check valves. This unit achieves highly efficient separation of water molecules from impurities, guaranteeing consistent and stable output water quality.
• Post-treatment Unit: Includes a purified water storage tank, an ozone sterilizer (optional), an EDI ultrapure water module (optional), a concentrate water recovery pipeline, a corrosion-resistant powder-coated frame, and food-grade stainless steel piping. This unit is designed to meet diverse requirements for water quality upgrades and enhancements.

Customization Service Details: All components within the Reverse Osmosis system series can be customized to utilize specific brands designated by the client. The use of standard-configuration brands is not mandatory. Additionally, the system supports exclusive customization for various voltage levels and frequencies (Hz), ensuring full compatibility with diverse power supply environments—including standard utility grids, marine power systems, and temporary construction site power setups.

3. Standardized Workflow for Reverse Osmosis Systems

3.1 Core Operating Principles

Reverse osmosis systems utilize a high-pressure pump to apply an operating pressure of 12–28 bar, forcing water molecules to pass in reverse through a high-precision RO membrane to achieve water purification.

Driven by this pressure, only water molecules are able to permeate the microscopic pores of the RO membrane. Various impurities, ions, and microorganisms present in the water are effectively retained and subsequently discharged from the system along with the concentrate, thereby achieving a complete separation between the purified water and the concentrate. The desalination rate of the reverse osmosis equipment remains consistently above 97%, purifying raw water to a product water TDS level of ≤5–40 ppm—fully meeting a wide range of water purification standards.

3.2 Fully Automated Workflow

1. Raw Water Extraction and Pre-treatment: Raw water pumps draw water from the source, subjecting it to multi-stage filtration and chemical conditioning to remove impurities and reduce hardness. The influent turbidity is maintained within 0.5 NTU, thereby meeting the specific intake standards for the RO membranes.

2. High-Pressure, Stabilized Delivery: The pre-treated water—now meeting quality standards—is pressurized to a preset level by a variable-frequency high-pressure pump and delivered smoothly into the membrane modules. This process prevents pressure fluctuations that could otherwise compromise water production efficiency and shorten membrane lifespan.

3. Reverse Osmosis Filtration and Production: Under pressure, the raw water permeates through the RO membranes to generate purified water, while the concentrated reject water is either discharged via piping or recovered for reuse.

4. Purified Water Storage: The purified water, once verified as meeting quality standards, is automatically stored in a dedicated storage tank. Should the produced water fail to meet standards, the reverse osmosis systems will issue a warning and halt production. The RO system produces water only when operating under normal, optimal conditions, thereby ensuring that no substandard water is ever released.

5. Automatic Protection and Flushing: The unit automatically performs a low-pressure flush of the membrane surfaces during startup, shutdown, and standby intervals. Furthermore, the system immediately shuts down in the event of abnormal water pressure, electrical overload, water supply shortages, or water quality excursions, thereby safeguarding the core components.

6. Periodic Maintenance and Servicing: Based on accumulated operating hours and the degree of water quality fouling, a chemical cleaning protocol is initiated to remove contaminants from the membrane surfaces. This process restores water production performance and extends the operational lifespan of the membranes.
