2T Seawater Purification System
The system uses a seawater-specific reverse osmosis membrane, and core components (such as pumps and piping) must be made of SUS316 or higher grade stainless steel to resist seawater corrosion.
It typically integrates multi-stage pretreatment (such as filter cotton and activated carbon) to protect the RO membrane and is equipped with a PLC control panel for automatic operation, flushing, and high/low pressure protection.
Core Technology: The core technology is high-pressure reverse osmosis, typically requiring pressures of 6.0-8.0 MPa, far exceeding that of ordinary brackish water desalination systems (approximately 1.5 MPa). All flow channels must be constructed using chloride-resistant materials such as SUS316L stainless steel.
Equipment Composition: A typical system integrates multi-stage filtration pretreatment, a high-pressure pump and energy recovery device (for energy saving), seawater RO membrane modules, a PLC control panel, and a post-treatment unit.
Key Parameters:
Desalination Rate: Typically higher than 99.3% under stable operation.
Recovery Rate: Limited by the high salinity of seawater, the recovery rate is relatively low (approximately 15-30%), resulting in a large concentrate volume.
Energy Consumption: Early systems consumed approximately 5-8 kWh of electricity per ton of water; newer systems equipped with energy recovery devices can reduce this to 2.5-3.5 kWh.
