Special separation reverse osmosis membrane element series
Product introduction
Acid-resistant high-pressure reverse osmosis membrane element
Acid-resistant high-pressure reverse osmosis membrane element is suitable for desalination of acidic wastewater with high salt concentration.
Oxidation-resistant reverse osmosis membrane element
Oxidation-resistant reverse osmosis membrane element is suitable for desalination and TOC removal of oxidizing aqueous solution, especially purification of high-concentration hydrogen peroxide. The membrane element has the characteristics of high TOC and boron removal rate, and can be used in the preparation process of electronic grade hydrogen peroxide.
Amide solvent-resistant reverse osmosis membrane element
Amide solvent-resistant reverse osmosis membrane element has the characteristics of tolerance to amide solvents and is suitable for concentration treatment of DMF, DMAc and NMP aqueous solutions. It is widely used in the concentration and reduction of related solvent-containing wastewater and waste liquid.
Heat disinfection membrane element
The heat disinfection membrane element can withstand temperatures up to 85 ℃. The unique shell design and removable end cover can effectively avoid element fouling and bacterial growth. It is the best product choice for applications with hygienic design requirements. This element is widely used in evaporator condensate recovery, material concentration in the food and pharmaceutical industries, and water use in the pharmaceutical industry.

1. The maximum temperature for continuous operation at pH above 10 is 35°C;
2. Under certain conditions, the presence of residual chlorine and other oxidants can cause premature membrane failure.
It is recommended that users remove residual chlorine by pretreatment before it contacts the membrane.
