The Industrial 500L 2 stages stainless steel RO water purification machine is an industrial reverse osmosis system designed to supply stable purified water for continuous production environments. With a rated capacity of 500 liters per hour, it supports manufacturing processes where water quality consistency plays an important role in product stability and operational continuity.
This equipment adopts a two-stage RO configuration, allowing progressive filtration for improved control of conductivity. The stainless steel structure supports durability in industrial workshops and allows the system to integrate naturally with existing production lines.
Structure of the Industrial 500L 2 Stages Stainless Steel RO Water Purification Machine
The machine is composed of multiple functional units that work together as a complete industrial water purification system.
Pretreatment System
The pretreatment system is designed to stabilize feed water conditions before entering the RO membranes. It helps reduce suspended solids and improve inlet water consistency, which supports smoother system operation during long-term use.
In industrial applications, pretreatment plays an important role in protecting downstream components and maintaining overall system stability.
Security Filter
After pretreatment, water passes through a security filter to remove finer particles. This additional filtration step reduces the risk of particulate load on RO membranes and supports more consistent system performance during continuous operation.
High Pressure Pump
The high pressure pump provides the necessary operating pressure for the reverse osmosis membranes. Stable pressure delivery supports reliable filtration performance and predictable water output during daily operation.
RO System (Two Stages)
The RO system is configured with two filtration stages:
The first RO stage removes the majority of dissolved salts and impurities.
The second RO stage further refines water quality, providing more stable permeate parameters.
This dual-stage configuration is suitable for industrial processes that require stronger control of water consistency rather than basic purification only.
Electrical Control System
The electrical control system supports coordinated operation of pumps and filtration units. It allows operators to monitor system status and manage daily operation with clear logic, supporting practical use in factory environments.
Working Process of the Industrial 500L 2 Stages Stainless Steel RO Water Purification Machine
The system operates according to a structured purification process:
Raw water enters the system
Pretreatment filtration stabilizes inlet water quality
Security filtration removes fine particles
High pressure pump delivers operating pressure
First stage RO filtration performs main purification
Second stage RO filtration further improves water quality
Purified water is delivered to storage or production line
This process structure supports predictable operation and consistent output during industrial use.
