Screening for Risk of Sexual Victimization and for

The screening mandated in the Standards aims to identify individuals during the intake process who are at risk of sexual victimization or abusiveness as part of an overall classification system Such screening, however, is a complement to, not a replacement for, good professional practices, and the information obtained through it should be used to

Separation and purification Filtration and screening

Separation and purification Separation and purification Filtration and screening: In filtration, a porous material is used to separate particles of different sizes If the pore sizes are highly uniform, separation can be fairly sensitive to the size of the particles, but the method is most commonly used to effect gross separations, as of liquids from suspended crystals or other solids
