The Process of Reverse Osmosis Water Filtration
The reverse osmosis process consists of several key stages that work together to produce purified water.
- Pre-Filtration:
Before water enters the reverse osmosis system, it undergoes pre-filtration to remove larger particles and sediments. This step ensures that the semi-permeable membrane remains free from clogging, prolonging its lifespan and maintaining the efficiency of the entire process. - Pressurization:
The pre-filtered water is then pressurized using a pump. This pressure is crucial for overcoming the natural osmotic pressure and forcing the water through the semi-permeable membrane. The pressure required varies depending on the feedwater quality and the desired quality of the purified water. - Semi-Permeable Membrane:
The heart of the reverse osmosis system is the semi-permeable membrane. It is a thin, porous barrier with incredibly tiny pores that allow only water molecules to pass through while blocking larger particles, dissolved salts, minerals, and most contaminants. As the pressurized water moves through the membrane, it leaves behind impurities, which are then flushed away as reject water. - Separation of Pure and Reject Water:
As the pressurized water passes through the semi-permeable membrane, two streams are produced: purified water (permeate) and water containing the concentrated impurities (reject or brine). The reject water, carrying the removed contaminants, is channeled away for appropriate disposal or recycling. - Post-Filtration:
The purified water, now devoid of most impurities, undergoes post-filtration to further enhance its quality and taste. This stage may include additional carbon filtration or other polishing treatments to ensure that the final product is of the highest standard for consumption. - Storage and Distribution:
Finally, the purified water is stored in an 18.9L bottle, ready for use. The purified water can then be used in junction with our water coolers to provide homes and businesses with clean and safe drinking water.
