1. Features
High Desalination Rate: Utilizing reverse osmosis (RO) and nanofiltration (NF) membrane technologies, it achieves extremely high removal rates of pollutants such as salts and organic matter in concentrated wastewater, meeting stringent requirements for industrial recycling.
Strong Adaptability: Capable of treating complex concentrated wastewater from various industries (e.g., chemical, electronics, power), with process parameters adjustable based on water quality.
Water Conservation and Emission Reduction: Converts wastewater that would otherwise be discharged into usable water resources, significantly improving industrial water reuse rates and reducing wastewater discharge.
Compact Footprint + Automation: The equipment is largely modular and integrated, requiring minimal space; it is equipped with an automatic control system for stable operation and ease of use.
2. Working Principle
The core process achieves concentrated wastewater purification and reuse through a combination of “pretreatment + deep desalination + post-treatment”:
Pretreatment: The concentrated wastewater first undergoes precision filtration, softening, and activated carbon adsorption processes to remove suspended solids, colloids, hardness, and some organic matter, preventing subsequent membrane module clogging or damage.
Deep desalination (core): The pretreated concentrate enters a reverse osmosis or nanofiltration system. Under high pressure, water molecules permeate the semi-permeable membrane to become permeate, while salts and large molecular pollutants are retained by the membrane in the concentrate.
Post-treatment: The permeate then undergoes pH adjustment, disinfection, and other treatments to ensure its quality is perfectly suited for reuse scenarios (such as cooling water makeup or process water) before being delivered to the point of use.
