Reasons Of Having Slow Flow In Your Ro Water Purifiers

Reverse osmosis (RO) is a water filtration system that physically separates the dissolved solids and minerals present in the water. The RO water plant technology makes use of the principle of osmosis, which basically works on the method of application of high pressure, reducing the mineral concentration of raw water through a semi-permeable membrane.

Let us explore why the slow flow might be an issue in your RO water plants in detail and know how to resolve it.

Clog in the RO filters

Whether we talk about home RO water purifiers or industrial level RO water plants used by large commercial units; the process is the same. No matter on what level reverse osmosis is working, it is mandatory to replace the filters periodically. The system fails to produce as much water as it used to if one forgets to change the water filters. More often than not, a clogged filter is the only cause of slow filling RO tank. Clogged filters and fouled membranes can make water filters take 4-6 hours to fill which would usually take 2-4 hours.

Replacing the filters on time can make all the difference; make sure to find ways to remember when is the time to replace the filters from your RO water purifiers.

Low air pressure

The air pressure inside the RO tank could also be affecting the speed of water flow. Ideally, even the empty tank should have a pressure of 7 to 8 psi. When you notice the slowed-down flow of water, check the air pressure in the tank; for that, remove any stored water from the tank, look for the blue plastic cap on the side of the tank that you will find covering the Schrader valve. Make use of a pressure gauge to understand the air pressure. While you check, if you notice the flow to be low, make sure to add in enough air with the pump until you have 7-8 psi. Add a small amount of air at a time because too much air pressure can puncture the air bladder.

Punctured tank bladder

If the normal pressure allows you to get a single cup of water and you notice the water instantly dripping down to a tiny stream, it could be an indication of a punctured air bladder in the storage tank. The thing about the tank bladder is that it can only be replaced and repaired.

Knots in the water line

If there are any knots or kinks in the waterline, it could slow the water production and flow. Inspect your system well to check if there are any knots in the waterline. Make sure you go about and double-check that the supply line valves are in a totally open position at the time of RO plant installation.

Water pressure changes

Typically, RO water filters need a pressure of at least 40 psi; however, 60 psi water pressure allows it to perform at optimal efficiency. The water could also get affected temporarily if your area’s municipal water supplier carries out any Maintainance work. It affects how your RO water purifier performs temporarily. If you notice it goes on for a long time, get in touch with the local authorities or water utility company in order to find out what is exactly wrong with the water pressure.

In Summary

The above mentioned are some of the common causes of having slow flow rates from your RO water plants. If none of the above-mentioned issues seems to be a problem for you, then you must consult the water treatment specialists in your area.
