Reverse osmosis membrane Nanofiltration membrane ・An organic-inorganic hybrid membrane was

developed.

・Improvement of polymerization reaction and

development of uniform membrane formation

technology to realize technological advances.

・Achieved a chlorine-related membrane which largely

exceeds conventional membrane resistance.

・Energy consumption was reduced by more than

50% through simplification of membrane

preprocessing and high permeability.

・Interface polymerization method for NF

membrane skin layer was improved.

・Filtration quantity of water more than doubled

in comparison with current NF membranes

while maintaining high performance with flat

membrane performance.

・A new trial element enables energy saving of

more than 50% for current NF membranes.
