Unit operations are the physical operations to remove the impurities present in the water and waste water where as the unit processes are the chemical and biological conversion on the status of the impurities that they will be easily removed by chemical or biological processes, both are applied especially to make the fine colloidal particles to coalesce and grow in size to be removed from the water or waste water.
