Reverse Osmosis (RO) is a process through which water is filtered and purified by pressuring it through a series of filters. Water is pumped into a so called “reverse osmosis water tank”, which then has its interior pressure raised. This pressure will push the water through a filter with tiny holes in it that are roughly the same size as a water molecule. This way, bigger particles are retained on the surface of the filter and in the first chamber. Then, the water goes through a second filter, which is made of carbon. The carbon is used to create a chemical reaction with minerals in the water, in order to retain and replace them. But for this process to work, pressure is essential. Some indications say that a pressure of 35 psi in the reverse osmosis water tank is enough for the process to be efficient. But the truth of the matter is, that a pressure of at least 45 psi is needed for the resulting water to not be considered compromised. A reverse osmosis system operating with a low pressure produces lower quality water, more reject water and less drinking water in general.
RO storage tanks run optimally at 60 psi, but they run even better at pressures that are around 80 psi. This can be achieved with a water booster pump. A booster pump is comprised of three essential parts: a transformer that is plugged into your wall, providing electricity to the pump, the pump itself and the pressure switch, which keeps track of the pressure in the tank, switching the pomp on and off whenever the pressure gets too low or too high.
So when would you need an Aquatec Reverse Osmosis booster pump? Well, if you live in a city, you will probably be fine with a water pressure of 60 psi or more. You will have to verify the water pressure you get. If this is the case, you can hook your reverse osmosis system straight to the mainline. A booster pump works well when the mainline water pressure is below 50 psi. A booster pump will help pressurize reverse osmosis tank, fill it quicker with water, it will improve its efficiency by helping the system produce more usable water and less reject water, and it will give you a higher quality of water. The booster pump you will want to choose depends on the amount of water that you use. Different manufacturers have different types of pumps and the way they are distinguished amongst themselves is by the amount of gallons per day the reverse osmosis unit produces. If you have a heavy-duty reverse osmosis system you will need a heavy duty pump and vice versa.
At the end of the day, even though reverse osmosis systems seem hard to understand, they really are not. The process is easy, the systems themselves are simple and troubleshooting any problem you might have can be done on the internet. The booster pump, just like an UV light purifying container are just ways to improve the quality of your system, and of your drinking water, when you have to.
