ULP ultra-low pressure membrane tube (high water volume and low desalination type, 4040, 8040)

ULP series products are ultra-low pressure aromatic polyamide composite reverse osmosis membrane tube components developed for surface water and groundwater desalination. Its operating pressure is about 2/3 of that of conventional low-pressure brackish water membranes, and its desalination rate can reach 99.5%. It has a high desalination rate and meets the water production demand under the low pressure condition of the system. It is mainly used in the desalination treatment of surface water, groundwater and municipal water with a salt content of less than 2000mg/L. Its application fields include packaged drinking water, quality water supply in communities or parks, food and beverage, etc. It has the characteristics of high water production, low operating pressure and good desalination performance.

P Series Membrane Tube

OLTRECAP - P Series

NF nanofiltration membrane tube (high desalination type, 4040, 8040) (applicable to: mineral water, water filling station)

NF series products are polypiperazine composite nanofiltration membrane tube elements with selective separation characteristics. It has a high removal rate for almost all bacteria, viruses, microorganisms, macromolecular organic substances, antibiotics, pesticides, pesticide residues and other small molecular organic substances, heavy metals and most divalent and above ions in water or solution, while retaining part of the sodium , Potassium, calcium, magnesium, metasilicate and other beneficial nutritional minerals and small molecular substances. It can be used for the preparation of direct drinking water, mineral water, softened water, partial desalination and decolorization of waste water with high salt concentration and organic matter concentration, and separation and purification of some inorganic salts, organic matter and other materials. The operating pressure of nanofiltration series products is extremely low, which can greatly save the operating cost of equipment or systems, and is widely used in drinking water, food and beverage, medicine, reclaimed water reuse, wastewater treatment and other industries.
