General The equipment has been designed and constructed according to D.P.R. n° 459 of 24th July 1996 (regulation for accomplishment of Norms 89/392/CEE, 91/368/CEE, 93/44/CEE and 93/68/CEE regarding the unification of States members laws in so far as machines are concerned). -
Page 5: Principles Of Working
REVERSE OSMOSIS SYSTEMS RO 809-812-815/E - INSTRUCTIONS MANUAL Principles of working Osmosis is a natural phenomenon : it is the spontaneous passage of a liquid from a dilute to a more concentrated solution across a semi-permeable membrane. The driving force of the solution through the membrane is its osmotic pressure. -
