Reverse Osmosis Water Treatment
Reverse Osmosis (RO) water treatment is one of the most comprehensive water filtration methods available. The multistage process pushes household water pressure through a series of filters. The first stage, a sediment filter, prevents sand silt and rust from clogging the RO membranes.
Minerals aren’t bad for you, but they can make your drinking water taste unpleasant. The reverse osmosis system reduces the dissolved minerals and other impurities that regular filtration can’t.
1. Removes Chlorine
Chlorine is commonly used in public water to disinfect it, but ingested chlorine can cause a variety of health problems. Reverse Osmosis systems use a carbon filter to remove chlorine from water and ensure that your drinking water is safe and healthy.
Reverse Osmosis uses a semipermeable membrane to separate drinking water from contaminants. When pressure is applied to the RO system, water molecules move from the less pure side to the more pure side of the membrane, leaving impurities behind. The RO system then filters the water down to a molecular level, getting it as clean as possible.
Every reverse osmosis system includes prefiltration, which usually consists of a carbon and sediment filter. This removes any particulates that could clog the membrane or damage the system.
Once the water has been cleaned to a molecular level, it is ready for drinking and cooking. Some systems also include a post-tank filter to reduce bacteria, cysts, and viruses. This is optional, and a Culligan expert can help you determine which system is best for your needs.
2. Removes Minerals
Reverse Osmosis is an osmosis process that uses higher pressure to push water molecules through a semi-permeable membrane, separating them from contaminants and minerals. Reverse Osmosis Water Treatment The heaviest minerals like calcium and magnesium are removed by this process. Other minerals like cadmium, fluoride and other chemicals are also removed through this process.
While many people are concerned that removing minerals from their water will make it unhealthy, this is not the case. The human body is able to receive healthy levels of magnesium and calcium through food sources and most minerals are not needed from drinking water. In fact, excessive consumption of magnesium can lead to muscle cramps and other side effects.
Some systems offer a remineralization cartridge that allows you to add some of these healthy minerals back into the water after it has been filtered by reverse osmosis. However, this should only be used as a supplement to a balanced diet. Attempting to raise the pH of the water and making it alkaline is a scientific misconception that has become a billion dollar industry.
3. Removes Hardness
Reverse Osmosis Water Treatment removes a lot of the Total Dissolved Solids (TDS) from water, including minerals like magnesium and calcium. These minerals are responsible for the formation of limescale on sinks and bathtubs. RO systems also remove many other contaminants from the water that cause a wide variety of other issues, such as clogged pipes and low lather in washing machines and showers.
Unlike distilled water, which is treated using evaporation and condensation, reverse osmosis uses a semipermeable membrane to filter the water. It has tiny pores that allow only water to pass through and traps other particles on the other side, where they are disposed of in the wastewater drain.
Reverse osmosis systems are often used in conjunction with a water softener to ensure optimum water quality for home use. High levels of hardness can lead to mineral build-up on the membrane and decrease the RO system’s effectiveness. A water softener can prevent this from occurring by removing the magnesium and calcium before it has a chance to foul the RO membrane.
4. Removes Chemicals
Reverse Osmosis is one of the only water filtration processes that can remove chemicals down to a molecular level. A RO system’s semi-permeable membrane has pores as small as 0.001 microns, allowing only water molecules to pass through while rejecting any contaminants. This includes dissolved salts, particles, colloids, organic material and bacteria (although it is not 100% effective in removing viruses).
These contaminants are Filling Machine Supplier filtered out because they do not have the same molecular weight as water. Additionally, they have a higher ionic charge and are larger than water molecules.
This enables the RO process to filter out unwanted substances without negatively impacting the quality of the water itself. In fact, a properly functioning RO system can remove 61 different contaminants and still deliver healthy drinking water.
For those who enjoy a well-stocked aquarium, a reverse osmosis water treatment system can also help remove toxins from the water that is used to feed fish. However, the resulting water is not good for humans, as it is too acidic. We recommend using an additional water filtration step to reduce the pH of the resulting wastewater, so it can be safely sent to a riverbed for natural filtering.
5. Reduces Waste
Reverse Osmosis uses a semi-permeable membrane to remove contaminants like chlorine, salt, and other sediments from water. It gets the water clean to the point that only pure H2O remains. The process also reduces waste.
Using reverse osmosis for industrial wastewater treatment allows companies to reduce water usage while still keeping the water clean. This helps to improve local water quality and it can help your business meet EPA regulations.
The process of reverse osmosis does produce some wastewater that has a high concentration of dissolved solids, which makes it unusable for drinking. This is called reject water or waste water and it can be used for other purposes in your home and office.
This water is good for cleaning, rinsing dishes, and mopping floors. You can even use it to irrigate plants and potted flowers. You can also add a remineralization cartridge to your RO system to return some of the beneficial minerals to your drinking water. This is a great way to enjoy bottled water quality in the comfort of your own home without all the extra packaging and environmental waste associated with purchasing bottled water.
