Reverse Osmosis water treatment system

Reverse Osmosis definition The movement of molecules across through a semi-permeable membrane from a higher concentration region to a lower concentration region is called reverse osmosis. This process is used successfully in water treatment. In this case semi-permeable membrane allow the water to passes through, but not allowed hardness forming metal ions and other bulk molecules such as Read more

Ion Exchange water treatment system

Ion exchange water treatment system is one of the most common processes and it is works on the basis on ion exchange principle. It removes the scale-forming calcium and magnesium and others metal ions from hard water. To removes these ions water are passes through ion exchange column filled with synthetic resin. Ion exchange column There are two type ion exchange column; cation exchange column Read more
