Reverse Osmosis Add a membrane flush kit

Add a membrane flush kit and extend the life of your RO membrane. The purpose of the flush kit is to help prevent scaling or fouling of the reverse osmosis membrane. By removing the contaminants(thru flushing) from the membrane it extends it’s life.

Membrane fouling is a process whereby a solution or a particle is deposited on a membrane surface or in membrane pores in a processes such as in a membrane bioreactor, reverse osmosis, ultrafiltration, microfiltration, or nanofiltration so that the membrane’s performance is degraded.

Membrane fouling From Wikipedia, the free encyclopedia

How a membrane works

A reverse osmosis membrane operation is one of unequal pressure across the membrane. There is a flow restrictor in the water leaving the membrane housing. This flow restrictor causes the water to slow down and create an unequal pressure across the membrane. This unequal pressure causes the water to push against the membrane allowing only the water particles to permeate the membrane as they move into the lower pressure area of the membrane.

What a membrane flush kit does

A membrane flush kit bypasses the flow restrictor providing a rapid rinse situation which washes away impurities from the membrane and allows the membrane to clean itself. Under sink units not fitted with flush valves, can easily add them. After adding the flush kit you will need to flush the membrane on a timed basis.

How often do you flush the membrane?

Once per month or every other month(depends on water demand usage) drain the water from your holding tank(open the RO water spigot) and wait for it to drain then close the spigot. Now, as the tank is trying to refill open your RO membrane flush kit valve and let the membrane flush itself for five to ten minutes. Then close the flush valve and wait for the holding tank to refill. That’s it you’ve accomplished an RO membrane flush.

 

How do you know if it’s working?

The use of a TDS meter will help you determine your membrane’s cleanliness. Measure the water before flushing the membrane and again after flushing. The difference in TDS is how well the procedure has cleaned your membrane.

Verified Purchase

This little baby lowered my TDS from 9 PPM to 0 PPM. I run it for 1 minute before and 1 minute after I fill my tank. It has taken about 6 weeks (I fill my 5 gallon tank once a week) to neutralize my membrane but slowly, I have seen my water quality and taste improve tremendously. I have the Hydro Logic 100GPD Stealth RO System with a booster pump and UV filter. I haven’t bought bottled water in about 6 months because I filter my city tap water for drinking. It tastes as good as any water I’ve tried, except for the Icelandic Spring water which has a very sweet taste.

Working with the reverse osmosis fittings

I like working with the fittings on my reverse osmosis system. They are super easy to connect and almost as easy to disconnect. The fittings are the push type connectors. It is these super easy connectors that make this modification a snap to complete. This two-minute video shows you how to connect and disconnect the tubing. It also gives you a cutaway view that shows the internals of the fittings and how they give you a watertight connection.
