Membrane Troubleshooting
Just want to share my experiences about membrane
troubleshooting. Every time clients are complaining to me about the issue of
low production upon installation of the new membrane, I always tell them that
we have to test the membrane to confirm the issue. If clients are saying that
it is a factory defect, upon testing the membrane, I will rule out that it is
not factory defect but Customer’s Defect or Technician’s Defect.
What do I mean by this? First of all you have to understand that Reverse Osmosis is a technical concept and for you to fully understand the system, you have to know the Principle of Reverse Osmosis.
If someone will be saying that they know how to install the membrane but does not understand the concept, then that is where the problem always lies.
First every membrane has its own test protocol according to its applied pressure, production, NACL and recovery rate. When we talk of NACL, we are talking of the osmotic pressure, if someone will say they don’t know this but have installed so many membranes, do you think that guy is credible and competent enough to discuss issues about membrane trouble shooting.
Second, membrane production depends on feed pressure and flowrate. If you ask them what is the feed flowrate and they do not know the capacity of the pump head or the performance curve of the vertical motor that they are using? Patay na!
How about the capacity of the feed pump? Is it capable enough to sustain the requirement of the RO module? What is the assumptive delivery volume of the said pump once it reaches the pump head?
These are just some of the things to consider when designing a system or doing the membrane troubleshooting.
The membrane is the most sensitive part of the basic systems that we are selling (WRS Set-up) any deviation from the technical design would affect its performance.
The main issue is what part of the system is contributory to the failure of the membrane. That is where troubleshooting comes in. Sabi ko nga uli,”You Hit the Nail by the Head”. Others are doing the “Guessing Game” or others will be doing it their own way, sabi nga may sariling concept, habang gumagawa nga sila kumakanta pa ng “MY WAY ni Paul Anka”
I am telling you all of these not to offend others doing their livelihood but to inform them the need to enrich their knowledge so that they can became useful and not damaging to the Water Industry.
For me, I never stop reading water treatment articles and I even ask my friends if I have doubts on certain issues. I am not saying na sobrang galing ko, in fact marami pa ko di alam and how I wish na mas marami akong ma meet na tao na magagaling sa Water Treatment para lalo pa ko matuto.
I just try to see that what I am doing is within the bounds of water filtration and purification concept.
