The difference between the reverse osmosis pressure method and the heavy construction membrane method is the water purification method.
The heavy construction membrane method is a water purification method that uses a porous fiber called heavy construction membrane in a bundle.
While keeping the mineral content in the water intact, it completely removes dispersive particles, rust, mold, microorganisms, and viruses but it does not filter out
anions such as ammonia nitrogen and nitric nitrogen.
Reverse osmotic pressure is a method of passing water by applying strong pressure against osmotic pressure (membrane filter) with very fine holes.
Although it has the advantage of being able to completely remove harmful substances such as germs, and other foreign substances, it also removes all the minerals
that the human body needs, so it has disadvantage similar to those of distilled water
