Product Introduction

AR (Acid Resistance) series acid-resistant nanofiltration membrane elements have the characteristics of strong acid resistance stability, high desalination rate, high pressure resistance and anti-fouling, which can ensure stable operation under strong acid conditions. They are suitable for industrial wastewater treatment scenarios such as titanium dioxide production wastewater treatment, metal processing wastewater treatment and mining wastewater treatment, as well as acid concentration scenarios in the chemical industry and pharmaceutical industry. The element can remain stable in 20% sulfuric acid, phosphoric acid, nitric acid and 15% hydrochloric acid, with a molecular weight cut-off of 200Da.

Product Features

Super Strong Acid Resistance

Can operate stably in extreme acidic environments; the membrane element can withstand strong acid environments with pH value exceeding 0;

High Separation Precision

Molecular weight cut-off around 200Da, with rejection rate of over 99.5% for heavy metal ions such as Fe and Ni, enabling selective separation of materials and acid solution concentration;

Strong Anti-Fouling Performance

Adopts short membrane leaf design, combined with low pressure drop feed channel technology, reducing pollutant deposition on the membrane surface, lowering cleaning frequency and extending service life.
