Charging, surface minimisation

The usual method adopted for minimising the accumulation of charge in the impact zone consists of making the sample surface conductive by depositing a thin layer of metal however, it is not always possible to deposit a thin and continuous layer on a coarse solid and a thicker deposit may conceal fine textural details. [Pg.136]

Unlike PA membranes, polyether urea (PEU) membranes are neutral to shghdy positive. PEU (and CA) membranes, unhke aromatic PA membranes, have a smooth surface and are, therefore, less prone to fouling [23], For RO feed water such as surface and municipal water, which are treated with cationic polymeric coagulants, PEU membranes, not negatively charged PA membranes, are used to minimise fouhng. [Pg.24]
