Extremely low pressure reverse osmosis membrane OV-X
● Second stage of wastewater recycling
● Drinking water purification
● Boiler makeup water
● Municipal water supply
● Product performance and characteristics
The new generation of OVAY Technology Extra-low Pressure (X) series optimizes the membrane making process of membranes, which has higher water flux and desalination rate compared with the previous generation, and has better pollution resistance. The membrane element is suitable for desalination and advanced treatment of raw water with low salt content, such as surface water, groundwater and tap water with salt content less than 1000 ppm, and can achieve high water yield under extremely low operation pressure or small membrane area. It can be widely used in the second stage of wastewater recycling, purification of drinking water of various scales, boiler make-up water and other fields, and is also an ideal choice in the field of municipal water supply treatment with surface water and well water as water sources.
