Direct Flow Reverse Osmosis System Vs Natural Process

Reverse osmosis systems can be compared to the natural process of water purification. Let us see what each of them has to offer – Cost, side effects, energy efficiency, and the Natural process. Which one is better for you? Keep reading to learn more! There are several reasons why you should choose a direct flow reverse osmosis system. Here are a few of them.

Natural process

A natural process of osmosis is where the solute and the solvent are mixed together and moved from one side of the membrane to the other. The pressure generated by this movement is known as osmotic pressure, and in reverse osmosis, this pressure is reversible. However, unlike other membrane filtration processes, reverse osmosis does not happen naturally. In order to achieve this, reverse osmosis requires hydrostatic pressure and a force to force the high-solute solution through a specially-designed membrane. This force forces the high-solute solution through the membrane, leaving a low-solute solution on the other side.


A reverse osmosis system requires a storage tank to collect and purify the water. A conventional reverse osmosis system produces fifty to one hundred gallons of clean water per day. A direct flow system does not require a storage tank and filters water as it runs through the faucet. The most important feature of a direct flow RO system is its high flow rate. It can process up to eighty gallons of water per minute and produces clean water that is better than bottled water.

Side effects

A reverse osmosis system reverses the direction of water molecules, moving them from a high concentration to a low concentration. In this process, a synthetic membrane lets only water molecules pass and permits very few other molecules to pass. This results in a water concentration that is about 80 percent less than that of the source water. The remaining source water contains Water Filter System Made in Germany a higher concentration of contaminants.

Energy efficiency

The energy efficiency of a reverse osmosis system is dependent on its GPD (gallons per day) rating. This is based on how often you use your filter and how much water you produce during the filtering process. A standard RO system collects contaminants within the filter media, but this technology uses cross filtration to remove pollutants by allowing the water to sweep them off the membrane.


When choosing a reverse osmosis system, you should know the type of water that it processes. You should look for a system that can handle the water pressure that your home typically has. There are two types of systems, the direct flow type and the reverse osmosis type. If you live in an area that has low water pressure, you should opt for the direct flow type.


Installing a reverse osmosis system requires a minimum water pressure of 2.7 bar/40 psi. It consists of a large 10 inch filter and a flushing system for membrane fouling. Additional post filters can be added if your water contains specific contaminants. Installation is easy and requires minimal plumbing knowledge. Ensure that your water supply meets the NSF standard for drinking water.
