Industrial 500L 2-stage Stainless Steel RO Water Filtration Machine

The Industrial 500L 2-stage stainless steel RO water filtration machine is an industrial-grade water treatment system developed to provide stable purified water for manufacturing processes. With a production capacity of 500 liters per hour, the system is suitable for production lines that require a consistent and predictable water supply.

The machine is commonly installed as a central water treatment unit and connected to downstream equipment such as mixing systems and filling lines, supporting daily production operations with continuous water output.

The Structure of Industrial 500L 2-stage Stainless Steel RO Water Filtration Machine

The Pretreatment Section Forms the First Structural Stage of the RO Water Filtration Machine

The pretreatment section is installed at the front of the system and consists of quartz sand filters, activated carbon filters, and softening resin units.

• Quartz sand filter removes suspended solids and sediment from the incoming water.

• Activated carbon filter absorbs chlorine, organic compounds, and odors to protect the RO membranes.

• Softening resin unit reduces hardness by removing calcium and magnesium ions, preventing scale formation on RO membranes.

This section ensures stable inlet water quality for the downstream RO stages, protects the membranes from fouling or damage, and maintains consistent system performance during continuous industrial operation.

The Precision Security Filter Protects the RO Membranes

A precision security filter is installed after the pretreatment section and before the RO membranes to remove fine particles remaining in the water.

• Protects the RO membranes from clogging or damage

• Ensures stable and reliable operation of the RO system

• Helps maintain consistent high-purity water quality for industrial applications

The 2 Stages RO Unit Forms the Core Filtration Structure of the System

The two-stage reverse osmosis unit is the central component of the machine. It is equipped with high-performance RO membranes arranged in two filtration stages:

• First stage RO membranes remove the majority of dissolved salts, hardness, and impurities.

• Second stage RO membranes further purify the water to meet industrial-grade quality standards, ensuring reliable output.

The staged configuration allows progressive filtration, producing high-purity water for production lines while supporting continuous and stable operation.

The Stainless Steel Piping Structure Connects All Functional Modules

The stainless steel piping system connects the pretreatment section, the two-stage RO unit, and the water outlet.

• Designed to maintain controlled water flow and system pressure

• Reduces risk of leakage

• Ensures efficient water transfer throughout the system

This piping layout provides smooth integration between modules and allows the machine to be easily connected to other production line equipment.

The Stainless Steel Frame Provides Structural Support for Industrial Installation

The stainless steel frame forms the mechanical foundation of the machine and supports all major components, including the pretreatment section, RO unit, and piping.

• This setup ensures stable operation of the industrial RO water purification system.

• Allows the machine to operate as a standalone unit or be integrated into a overall production line

The frame design provides flexibility for different industrial setups while ensuring long-term reliability.

The Control and Instrument Layout Supports System Operation and Monitoring

All control components and monitoring instruments are optimally arranged to provide easy operation

• Operators can monitor water quality, pressure, and flow in real time

• Simplifies system management

• Ensures reliable, continuous operation

This setup guarantees that the entire system functions efficiently and supports industrial production needs.
