As per concept presented in Part 1, now comes my personal evaluation and interpretation.
The “longer the stages the cleaner the water concept” is a marketing style wherein it tries to present to the public that water can reached it’s highest purification level as it passes through the series or stages of filtration.
This was the concept that was imprinted in the minds of the consumers and even water station owners.
In broadcasting business, there is what we call, “responsible journalism”, I hope someday, we can have a sort of responsible marketing in the water business.
We should be informing the public the right information so that our technology will improve and grow. We should not be living in false concept and beliefs.
When we talk of “QUALITY water” for drinking application, we should consider its physico-chemical properties, bacteriological aspects (pathogenic) and now DOH are considering the heterotrophic platelet count (HPC).
The moment water quality satisfies the parameters mentioned above, and then water is of drinking standard regardless of the number of stages.
The logic is that, number of stages does not guarantee the quality of drinking water, what matters most, is the accuracy of treatment used in a given quality of raw water.
Whether it is 2, 3 or 4, etc., as long as the system will be capable of producing drinking quality water, then there is no issue on the no. of stages.
In fact, if you are to refer on the Implementing Rules and Regulations of BFAD (IRR) Section 3 paragraph 3,Drinking water is defined as, WATER OBTAINED FROM AN APPROVED SOURCE THAT HAS UNDERGONE MINIMUM TREATMENT CONSISTING OF FILTRATION(ACTIVATED CARBON OR PARTICULATE) AND OZONATION OR EQUIVALENT DISINFECTION PROCESS.
Even BFAD and DOH never mentioned of the no. of stages, so why are we stressing a certain concept that is non-existent?
It is for you readers to decide if the concepts that I have discussed can be considered or not.
