Water purification systems are important because water is essential to our survival. We drink it, bathe in it, cook with it, wash dishes with it, and even clean ourselves with it.
However, most of us don’t realize just how dirty our tap water is until we see the results of a water test kit. That’s why it’s important to invest in a high quality water filtration system.
But which type of water filter should you buy? Should you go with forward osmosis or reverse osmosis? In this article, I’ll explain the differences between these two types of filters and tell you which one I recommend.
What does forward osmosis do?
Filtration is a method for filtering out impurities from water. It works by passing the liquid through a membrane which allows some molecules to pass through but not others.
What does reverse osmosis do?
Reverse Osmosis (RO) is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water.
Forward Osmosis vs Reverse Osmosis
Reverse osmosis is used to remove impurities from water. It uses a semipermeable membrane to separate pure water from contaminated water. The membrane lets pure water pass through while keeping contaminants inside.
In contrast, forward osmosis uses a semipermeate membrane to let pure water pass through while retaining impurities. The difference is that reverse osmosis requires a lot of energy to push water through the membrane, whereas forward osmosis does not.
For example, if you wanted to drink water that was 99% pure, you would need to spend $1,000 per year on bottled water. But if you had a reverse osmosis system, you’d only need to spend $100 per year on bottled water since the system would be able to filter out 99% of the impurities.
A reverse osmosis system will cost anywhere from $2,500-$10,000 depending on how large the system is. On the other hand, a forward osmosis system costs just $200-$300.
So if you’re interested in saving money, consider installing a forward osmosis water purifier instead of a reverse osmosis water purifying system.
Scaling & Fouling
In short, scaling and fouling are caused by organic and chemical residues, oxidants, and scaling ion buildup on the membrane surface. These substances reduce the efficiency of the membrane and require frequent maintenance and backwashing of the membrane.
But if you want to avoid scaling and fouling, then you might want to consider using a forward osmosis system instead. Forward osmosis systems are less sensitive to scaling and fouling issues, so they tend to last longer than reverse osmosis systems.
Membrane quality
Aquaporin Inside FO Membranes is made using natural aquaporin proteins. These proteins are found inside every cell in nature, and they’re extremely efficient at filtering out impurities. Because of this, Aquaporin Inside membranes is able to reject 99.9% of solids and 98% of bacteria.
This means that Aquaporin Inside filters will remove almost anything that isn’t water. And since they’re made with natural materials, there’s no risk of contamination or damage to the environment.
In addition to being highly efficient, Aquaporin Inside FO membranes is also highly durable. They’ve been tested against extreme conditions including high temperatures, low pressures, and salt concentrations. Their durability means that they won’t break down after repeated use.
So if you’re looking for a reliable, eco-friendly solution for removing impurities from drinking water, then Aquaporin Inside® is the ideal choice.
FAQs
Is forward osmosis better than reverse osmosis?
Ideally, a reverse osmotic (RO) filter should only be used for drinking water, but with the complex chemical makeup of industrial waste water, this is rarely the situation. Forward osmotic (FO) filtration uses relatively low pressures to push water through an RO filter, making the FO filter less susceptible to fouled membranes and scale buildup.
Conclusion:
Reverse osmosis (RO) is an effective water purification method that uses pressure to force water molecules through a membrane filter. This allows the water to pass through while retaining impurities such as salt, minerals, and bacteria.
Forward osmosis (FO), on the other hand, does not require high pressures to push water through membranes. FO works by using a semi permeable membrane to allow water molecules to flow freely across its surface.
This means that FO has no need for high pressures and therefore requires far less energy to operate. In addition, FO systems are typically smaller and cheaper than RO systems.
However, FO systems tend to produce lower quality drinking water because they cannot remove dissolved solids. Therefore, FO systems are usually used for industrial applications where purity levels are low.
