Choosing the right word
  • 隔離かくりCommon
    suru verb, transitive verb, intransitive verb, no-adjectiveSegregation in the physical sense of keeping a person or group apart from others with no contact, as in isolating the sick; it also covers quarantine.

  • 分立ぶんりつCommon
    noun, suru verb, intransitive verbSegregation in the sense of distinct bodies or groups standing apart as separate, independent units; for segregation as keeping people apart, it is seldom the word you want.
  • 分離ぶんりJLPT N1approx.Common

    The oil in mayonnaise sometimes separates from the other ingredients.

For segregation as physically keeping people apart, as in isolation or quarantine, use 隔離; for separating things into distinct parts use 分離; 分立, for entities standing independent, is seldom the right choice.
