Electrical Engineering/Water Purifier Machine.


QUESTION: Dear Prof Cleggsan



1. Can a Water Purifier be designed and constructed which is battery operated instead of the mains power ac supply ?.

2. Can a Remote control be designed for a Water Purifier Machine ?.

3. Which is a Better product among electrical and non electrical water purifier machines ?.

Thanks & Regards,
Prashant S Akerkar

ANSWER: 1. Yes.  But who needs it?

2. Yes.  But who needs it?

3. Electric water purifiers use electric power; non-electric purifiers use gravity feed and porous filtration schemes.  I suppose it depends a great deal on the type of impurities that one wishes to filter out.

Therefore, the selection of a water purifier will depend largely upon the type and level on various contaminants in the water and the rate of purification needed by the applicant.

QUESTION: Dear Prof cleggsan


Regarding point 3,if impurities are high
Which is a better product

Thanks & regards

That is not an electrical engineering question so I cannot respond as an expert.

The impurities can have a wide range of variables from chemical to salines to metals and to organic matter.

Not only the items in your impurity list but their level of contamination must be considered.  The rate or gallons/minute must likewise be considered; it must fit the needs of the user.


The above is a very practicle guide to selecting a filter system for American home usage.

And below is a tabulation of the kinds of impurities likely to be encountered and some filtering techniques to consider:


Doing the research is a very applications oriented procedure.
