Overview
Introduction
Reverse osmosis (RO) is a pressure-driven separation process that employs a semipermeable membrane and the principles of crossflow filtration. RO membranes are typically capable of removing 90%–99% of contaminants such as total dissolved solids (TDSs) in the water supply. The membranes are usually manufactured as a flat sheet of thin composite membranes consisting of an active polyamide layer (high permeability but impermeable to dissolved salts and particulate matter) supported by a porous polysulphone layer wound round a central collection tube. RO membranes are sized on their water volume production rate and the desired hourly or daily rate of water to be used.
Features
1. Total dissolved solids reduction: Reverse osmosis is one of the rare water treatment processes that can boast a total dissolved solids reduction.
2. Cost-effectiveness: Reverse osmosis is popular in industrial settings because it is highly economical compared with alternative filtration methods.
3. Eco-friendliness: Compared with other treatment methods, reverse osmosis is also relatively environmentally friendly. It uses less energy than other methods like thermal distillation because it does not rely on energy generation.
4. Alkalinity and hardness removal: Reverse osmosis removes the calcium and magnesium ions that contribute to hard water, as well as the carbonate ions that contribute to unwanted alkalinity.
