In unit process there is no any physical changes but chemical changes occur. but in unit operation no any chemical changes, only physical chages occur.

Unit process includes all the treatment methods in which the removal of contaminants is brought about by chemical or biological reactions.  It is considered as a secondary treatment.
While Unit Operation involves only the methods in which physical forces predominates. It is considered as primary treatment.

Unit operation is a basic step in the unit process. were Unit operations involve like evaporation, crystallization, separation etc., Example: In Milk processing for example
Homogenization, separation,Chilling and packing. each step is one unit operation and entire process is nothing but Unit process

The core of chemical engineering is all about unit operations and unit process. All chemical industries will do both process and operations. where operation is a physical change and process is a chemical change. The basic rule of a chemical reaction is : reactant-->physical change-->product(formed by chemical change)--> physical change--> packing

Unit Operation: Basic step in a process, involves physical change or chemical transformation
Eg- Separation, filtration, crystallization

Unit Process: One or more grouped operations in a manufacturing system
Eg- Milk processing (homogenization, pasteurization, chilling - unit operations in milk processing)
