Water purification process

摘要

Drinking water is prepared from crude water containing dissolved lypophilic contaminants by adding polymers of ethylene or substituted ethylenes or copolymers of ethylene with less than 50 % by weight of other ethylenically unsaturated monomers which may contain additionally less than 2 mole % of ethylenes carrying a carboxyl function, and separating the polymer substance containing the lipophilic contaminants.
