Continuous Ion Exchange Treatment Process for High Salinity Wastewater

Addressing the Challenge of High-Salinity Wastewater In the realm of wastewater management, high-salinity wastewater represents a formidable challenge. Characterized by a total salt content exceeding 1%, and laden with a mix of inorganic ions and organic substances, its complexity and inhibitive effect on microbial activity demand an advanced approach to treatment. Accounting for 5% of China's total wastewater volume and increasing annually by 2%, high-salinity wastewater treatment is not only critical but also a central focus of contemporary research. Traditional and modern methods alike—from ion exchange to biological treatments—struggle to effectively address these concerns.

Innovative Case Study: Dramatic COD Reduction A landmark project showcases the capacity of Sunresin's technology to tackle excessive COD levels, a common hurdle in high-salinity wastewater management.

 

High Salt Wastewater
Parameter Inlet Water Units
TOC 3000-4000 mg/L
COD 9000-11000 mg/L
pH 3.5-4.5  
Sodium Chloride 12 %
Fine Powder PPS ≤ 0.1 %
Suspended Solids ≤ 1 mg/L
Iron none mg/L

 

Initial COD measurements soared between 9000-11000 mg/L, far surpassing discharge standards. Utilizing the XDA series resin in a meticulously designed continuous adsorption-desorption system, integrated with an automatic control framework, resulted in reducing COD to below 500 ppm. 

This achievement not only meets but exceeds Class III surface water discharge standards, setting a new benchmark for industry performance.

System Features and Advantages Sunresin's continuous ion exchange system stands out for its:
