Nanofiltration Elements for Municipal Water Application: Tapurim Series
Introduction
Organic, microbes, viruses and most of metal ions with two or higher valence can be filtered by filtered by Tapurim Series NF element, while sodium, potassium, calcium, magnesium ions, etc. can be retained in the permeated water.
-
TAPU-LS Element is designed primarily for removal of organics while keeping most of the monovalent ions retained in the permeated water, and is applicable to removal of organics and inorganics from raw water with low salinity.
-
TAPU-MS Model has higher rejection rate of monovalent ions while maintaining a proper rejection rate or organics, which is applicable to the removal of organic and inorganic matters in mid-salinity raw water.
-
TAPU-HS has a rejection rate at 80-85% for chlorides, applicable to the rejection of organic and inorganic matters in mid and high-salinity raw water.
Application
This membrane element is developed by utilizing the technology of controllable porosity formation is separation layers, and is designed for waters with middle and high salinity too meet the requirements of healthy drinking water. The use of brand-new LD (low pressure difference) 34-mil feed channel spacer improves the fouling resistance while reducing the energy consumption. The entire series of elements have been officially authorized by "Hygiene Permit for Products Related to Drinking Water Hygiene Safety", thus ensuring the safety of membrane element application.

Material Separation NF Membrane Elements: MASE Series
Introduction
Material Separation NF Membrane is primarily used in separation of monovalent salt and divalent salt, as well as hardness removal, denitration separation and concentration of liquid, with the molecular weight cutoff covering 200~800 Dal.
-
MASE-SP is designed to reject part of the multivalent ions while allowing the permeation of monovalent ions, and is applicable to purification of high-concentration saline water.
-
MASE-SL is designed to reject the multi-valent ions and organics while allowing the permeation of monovalent ions, and is applicable to purification, decolorization and organism rejection of high-concentrated saline water.
-
MASE-PS has a moderate rejection rate of monovalent ion, applicable to rejecting organics such as pesticide, herbicide, etc. in high-salt water.
-
MASE-CR has a high rejection rate of monovalent ion, which can be applied in the reuse of rejected water with 5000~10000ppm salinity.
Application
The use patented Uarc water distribution endcap ensures more even distribution of hydraulic load on the end surface, thus reducing the accumulation of pollutants. The use of brand-new LD (low pressure difference) 34-mil feed channel spacer improves the fouling resistance while reducing the energy consumption. The end cap adopts thermal-melt spin welding technology to enhance the structural strength of the membrane element and ensure stable operation of the membrane element under a high pressure difference environment. The use of hi-precision spiral-winding technology and low permeate resistance structure decrease the overall fouling rate of membrane element, thus maximizing the working efficiency of membrane element and effectively reducing the operational costs.
