Regulations prohibit us to purify harmful substances. The techniques are filtration etc. Microorganism is also used to purify.
Microbes are also used to purify.
In Chemical Engineering, distillation, filtration, crystallization and reaction are studied to do efficiently on a large-scale.
Because of the large-scale, System Engineering ( Control Engineering ) and Fluid Mechanics is studied together.
Chemical Engineering is one of the factors of Environmental Problems . But it could be one of the method to solve the problem.
Environmental engineering is developed from civil engineering. Some experts of civil engineering studied methods for the environmental problems.
Environmental engineering studies the function of the city. But if we want to study them with designs of histories and cultures, we need to use the fuudo technology .
