Answer:

Minimizing the use of water for processing by reusing and recycling it, is done in two or more successive stages.

Treatment of industrial effluents can be done in three phases:
(a) Primary treatment by mechanical means.
This involves screening, grinding, flocculation and sedimentation.
(b) Secondary treatment by biological process.
