# Impurity Extraction Process
[](https://stanslegacy.com/uploads/images/gallery/2023-12/SfsY9Ms8MRP5eM0o-image-1703197304479.png)Suspended and dissolved **water contaminates** (144a xxx 144n) (*typically 20 ppm to 40 ppm in natural water*) of Figure (3-24) being uniformly released from and superimposed onto remaining **water bath** (68) during **Resonant Action** (170) are directed to and passes through **water inlet line** (145)
... causing liberated, moving, and free-floating **micro-sized contaminates** (144a xxx 144n) to be deposited inside **Electrostatic Filter Assembly** (440) and subsequently exposed to **opposite electrical voltage fields** (148/152), as so illustrated in Figure (3-45).
**Negative electrically charged contaminates** (157a xxx 157n) migrates to and entrapped by **positive electrical voltage post** (147); while, simultaneously, **positive electrical charged contaminates** (158a xxx 158n) are attracted to and entrapped by **negative electrical voltage post** (151)
... thereby, extracting **contaminates** (144a xxx 144n) from **water bath** (68)

... producing **purified water bath** (156) which is recycled back into **Fuel Cell** (120) of Figure (3-24) since **Resonant Action** (170) also function as and performs as a **water-pump** (Gas rising).
Exposing **water contaminates** (144a xxx 144n) to **applied voltage fields** (E1/E2) not only produces **electrical charged contaminates** (157/158); but, also, kills bacteria that might be present in **water bath** (68).
Periodically **back-flushing** (rinsing out) is all that is required to ensure and sustain **Electrostatic Filter Process** (440).
