1. Introduction
Automata drinking water
as – DWM-203) is manufactured by Aquaphor LLC, (Russian
Federation, Saint Petersburg).
DWM-203 is designed for after purification of drinking water
from solids and colloid particles, natural impurities. DWM-203
eliminates foreign flavor, the smell and color of water,
delivered by municipal and local water supply networks (water
from artesian well, pits etc.), meeting the requirements, set by
the present guidance.
The action of DWM-203 is based on the transfer of water
molecules through a semi-permeable membrane by pressure
application that is greater than the osmotic one.
pressure builds up with water salt content increase, so the
more water is mineralized, the greater the tap water pressure
is required for the performance DWM-203.
Materials DWM-203 are safe, non-toxic and do not release
into the water hazardous substances for human health and
the environment.
