Issues Concerning the 3000 GPD Reverse Osmosis System

Many things and concepts were discussed here about membranes. It was established that membrane production depends on so many factors. For you to establish a 3000 GPD production (single membrane) is comparable to running your car at a speed of 180 to 220 km/hour.

You have pushed the membrane’s performance to its maximum limit. In fact, if you are to compare our membrane design to other countries then you can see the major difference in terms of technical design.

A typical 3000 GPD in other countries is using 2 membranes. You know why? They are considering the safety factor. They are making a safe projection on the membranes performance.

Here in our country, we are doing the contrary, we are pushing the membranes to its maximum limit and as a result, membrane’s service life is shortened.

I’m just wondering, most of the package being sold today are single membrane with 3000 GPD production rating. You think that is right?

Mathematically speaking, if you divide 3000 by 24 and divide the answer by 60, you will have 2.083 GPM or gal/min. So if the client will see that production is below this, then he/she will say that the system is not right.

Since there are factors affecting the membrane production, it is difficult to establish 3000 GPD especially in places where TDS and Chlorides are high.

So, why mention 3000 GPD using single membrane? Why not mention 1500 or 2000 GPD?

What I am trying to point out is the level of professionalism when presenting the system. Clients have the right to be informed correctly, sabi nga transparency, hindi lang puro sales talk then later sablay pala, so apparently the credibility of the company or the person doing the system will fall down.

I don’t want to discuss more about this issue, but just a point to consider to all concerns.

Next time I will be discussing Fallacies about number of stages.
