20T/H Dual-Stage Reverse Osmosis Water Purification Equipment - Professional Water Treatment Solutions

Ⅰ. Core Technology and Advantages of Equipment

 20T/H dual-stage reverse osmosis water purification system adopts advanced reverse osmosis (RO) technology, which is a highly efficient solution for the water treatment industry. The system can remove more than 98% of inorganic salts, almost all organic matter and microorganisms in the water, ensuring that the effluent water quality reaches the standard of purified water.

Core advantages include:

 • Two-stage reverse osmosis design ensures ultra-high purity

 • Fully automatic operation, 24 hours unattended

 • U.S. DOW / Korea CSM imported RO membrane elements

 • 304 stainless steel structure, durable 10-20 years

Ⅱ. Complete process flow analysis

1. Pre-treatment stage:

 • Raw water booster pump to raise the water pressure

 • Quartz sand filter to remove suspended solids

 • Activated carbon filter to adsorb organic matter

 • Water softening device to reduce hardness

 • 10μm +5μm precision filtration double protection

2. Core treatment stage:

 • A high-pressure pump + RO membrane first stage purification

 • Intermediate water tank buffer storage

 • Two high-pressure pump + RO membrane depth purification

3. Post-treatment stage:

 • Pure water tank storage standard water

 • Online water quality monitoring to ensure quality

Ⅲ. Excellent technical parameters performance

1. Water quality: conductivity 2-5μs/cm (raw water <400μs/cm)

2. Desalination efficiency: system desalination rate of ≥ 98%

3. Automation function:

 • High and low voltage automatic protection

 • No water / water full automatic shutdown

 • Water quality exceeds the standard alarm discharge

 • Timing chemical cleaning prompt
