Portable water purifier; Wellspring; FAQ 2. Can Wellspring filter any types of water?

We have been asked this question many times.

But unfortunately, Wellspring cannot filter every types of water into drinking water.

Seawater is the representative case. Seawater cannot be filtered by the membrane which is applied to Wellspring.

 

As you know, seawater cannot be used for drinking water due to salt. Salt exists in ion form in water. The size of ion is way smaller than the size of pore on membrane.

The membrane which is applied to Wellspring has pore size of 0.1㎛ thus it can filter viruses and particles but cannot filter ion which is smaller than 0.1㎛.

 

If you would like to produce drinking water from seawater, you need to use reverse osmosis membrane which requires more energy and extra-cost. (Next posting will be principles of filtration by membrane)

 

For such reason mentioned above Wellspring cannot filter sugar in juice. This is unexpected but many of our customers have tried to filter coffee or juice by Wellspring and have been confused.

 

So what types of water can be produced into drinking water?

You can produce drinking water with surface water such as rain water, underground water (if it contains heavy metal or arsenic Wellspring needs additional filter), pond water, river water and etc.

Both clay water which looks dirty and water which looks clean but contaminated with microorganism or viruses can be filtered.

 

Wellspring can remove particular matter like clay, microorganism, viruses, rust and parasite in surface water. Also we applied activated carbon to Wellspring thus filtered water does not have odor and tastes good.
